Guppies are native to South America and the West Indies.

Maximum size and longevity

Sizes can vary from 3 to 5 cm.

Water quality
· Temperature: 24°C – 26°C.
· pH: 7.0-7.5
· General hardness: 250-300 ppm (if you start to get sick, doubling this dose can help).

Guppies need clean, oxygen-rich water, make sure tanks aren’t overcrowded, well ventilated, and filters cleaned regularly.
Make sure all biological filters are working properly, ensuring that no ammonia or nitrite is present.

Feeding

An active fish, guppies use a huge amount of energy and need to be fed at least 3 times a day with a variety of foods including dry, fresh, frozen or live food.

Guppies are surface eaters and will readily accept most prepared foods. However, they should be given a high-vegetable diet and a dry food like Spirulina should be used occasionally.

Compatibility

They are suitable for a community pond densely planted with other peaceful fish. It’s best to choose tankmates with slightly alkaline hard water needs in your aquarium.

Avoid crowding with larger or aggressive species that will nip them because of their colorful tails.

Male guppies can continually “harass” female guppies if kept together, this can be avoided in commercial situations by stocking males and females in separate tanks. This will stop continuous playback.

Color and varieties

While there are many beautiful wild forms of livebearers, guppies have been selectively bred around the world to produce a huge variety of colors, body and fin shapes.

Sexing

Viviparous fish have the common trait of giving birth by swimming young (ovoviviparous), rather than by laying eggs like most other fish. To achieve this, males have a modified anal fin called a gonopodium which is used to facilitate internal fertilization of the female. Once fertilized, the eggs mature inside the mother’s oviduct. The eggs then hatch
internally and give “birth” to the resulting offspring soon after.

Guppie fingerlings are about 7 to 10 mm long at birth and are probably the most easily bred species on finely ground dry food and do not require special food like most other species when they start feeding.

Males and females are usually easily distinguished as males have a smaller body with brightly colored tails, females also have a dark “gravid” patch in the anal region.

Its ease of reproduction means that it is the first species that many hobbyists start breeding.

General information

Guppies are probably the most popular livebearer among both aquarium owners and advanced breeders.

It has become a species of fish for hobbyists with selective breeding resulting in many varieties of spectacular coloring and fins. These fish are generally robust and tolerant of a wide range of aquarium conditions – for this reason they are often recommended for beginners.

However, due to intense selective breeding, guppies can be more difficult to keep than their wild ancestors.

For this reason, it is important to try to match the tank conditions to their requirements of slightly harsh and alkaline conditions, otherwise they can become weak and prone to bacterial infections. Will be prone to bacterial disease in soft water.

Interestingly, guppies introduced into empty home aquariums, where the water is well aged and there is plant life and algae to graze on, can transition from the previously described hard water with little or no ill effect. This is attributed to the higher levels of stress the fish are exposed to under commercial conditions, such as fish constantly entering and leaving the ponds, more handling and higher densities.

Burmese rummynose comes from Myanmar.
They have a limited distribution in Lake Inle and its surrounding waters.

Maximum Size and Longevity

Burmese rummynose can grow to a length of 4 cm, and will live for 2 to 3 years if kept in the right conditions.

Water quality

Rummynose Burmese may be temperature sensitive and prefer slightly alkaline water:

Temperature: 21-25°C

pH: 7.0 —7.5

GH: 150 – 250 ppm

food

Burmese rummynose are omnivores and generally eat a wide variety of foods. Be sure to provide food that is small enough for their tiny mouths.

Compatibility

This fish is quite peaceful in a species tank or in a community, although males can be skittish when in spawning condition. These fish live in schools in the wild and are best kept in groups of six fish, preferably more.

Color and Variety

A small silvery blue fish. Males develop red tips on the nose and fins.

sexual differences

The male has a “rummy-red” nose and red tips on the tail fin. Males have a milky or bluish coloration on the body and are usually larger than the female. Females are not red in color and are usually more silvery.

General information

As they are lake fish, they prefer little or no water movement. They color best when their natural habitat is replicated in a peaceful species or community pond. These hardy minnows prefer a heavily planted tank with places to hide. The tank must be covered, as these fish can jump if startled.

The ancient Chinese kept goldfish some 1600 years ago.
The original wild, drab coloured fish were selectively bred until the beautiful clear bright colours of today’s fish were developed.
The Japanese obtained some of these fish about 500 years ago and have developed some of the more unusual types of goldfish.
Today there are dozens of different types. Even though they are different colours and
have different body, tail and eye shapes, they are all the one species, Carassius auratus.

Maximum Size and Longevity

Goldfish are capable of reaching the grand old age of 20 years and attain a length of between 12 to 30cm, depending on variety.

Water Quality

· Temperature: 15°C – 20°C is the ideal range, however they can tolerate temperatures outside of this range.
Outside of this range however, they can become stressed and more prone to illness.

· pH: 7.0—7.5
· General Hardness: 150 ppm.

Feeding

A good staple food for goldfish is a high quality floating granule. The small size is best, as this assures all fish get their fair share. Feeding floating granules, two to three times a day, in the right quantities is one of the major factors in keeping goldfish healthy and active. For variety, occasionally substitute flake food, and, more importantly, some vegetable material.

Compatibility

Goldfish are best kept with other Goldfish, in a tank or pond. A good rule of thumb to minimise aggression is to keep straight tailed fish together with other straight tailed
fish, and fantailed fish with fantailed fish.

Colour and Varieties

Over 1600 years of selective breeding has resulted in a wide range of varieties and colours. The most frequently seen are divided into 2 categories: Straight (or Single)
tailed, such as the Comet, Shubunkin or Common Goldfish, and the Fantailed varieties such as the Fantail and Ryukin.
Ranchus and Lionheads have a double tail and no dorsal (top) fin. Orandas are well known for their short, globular body and characteristic head growth—this may take years to develop fully. Other varieties, less frequently available, include Telescopic eyed fantails such as the Butterfly Tail; Pom Poms, Bubble Eyes and Pearlscales.

Goldfish are available in a wide, seemingly limitless, range of colours. The most frequently seen is Red, which can be varying shades of orange red, orange and orange yellow. Calico and Shubunkin colouring refers to a mottled pattern of blue, red, orange, brown, yellow or black. Black goldfish are available, but they can tend to fade indoors.

Sexing

Small goldfish are difficult to tell apart. Larger fish at about one year old can be distinguished fairly easily. Males develop small white tubercles along the leading edge of the pectoral fins. When in breeding condition the tubercles can also be noticed on the gill plates.

General Information

Goldfish are hardy, colourful, easy to care for and the ideal beginner’s fish. They make a perfect first pet. As experience and interest levels grows, their fascinating history and wide range of varieties also ensures that they are highly prized by the enthusiast.

Although there are many species available, most common commercially available species are:
Aphyosemion sp – Killifish species
Aplocheilus sp, Epiplatys sp,
Pseudepiplaty sp – Panchax species

Maximum Size and Longevity

Killifish are usually small fish and, depending on the type of species, the size varies from 2 to 6 cm.

Panchax species will grow to a maximum size of 10cm.
Many of the Aphyosemion species are annual species and can only live for one year, while the Panchax group can live for several years.

Water quality

Water quality will vary depending on species, but as a general rule prefer mild acid water.

Temperature: 20oC – 24oC
pH: 5.5 – 7.5
General hardness: 50-150 ppm

Feeding

Killifish have a small mouth structure, so be sure to select foods that are suitable.

Compatibility

Many killifish can be safely combined with small catfish, small tetras and other non-territorial fish.

Do not keep them with larger predatory fish that would attack this small fish. They can also be kept alone in a small tank where they can readily display their amazing reproductive colors.

Color and varieties

The Killifish group has a very diverse color and great variety.

For example, many of the Aphiosemion species have brightly colored males. One possible reason for their bright colors is because they are commonly found in dark waters with low visibility and therefore need really bright and striking colors to attract females.

Tips to maintain successfully

These brightly colored fish are not fussy and are ideal for a community aquarium. They prefer a planted tank and softer water conditions on the acid side.

General Information and Reproduction

Some species in this group can lay their eggs in the substrate when their natural habitats dry up and the eggs hatch when water returns with rain.
Some killifish such as the Aphyosemion have also been called “annual fish” for this reason. Other species can spawn among floating plants and often reproduce in
densely planted community tanks. Males are often extremely colorful, while small females are subdued in their coloring.
Afiosemion species may be prone to velvet, but respond well to normal treatments for this disease.

Generally a robust group with no particular needs.

Discus is the common name given to all freshwater fish species classified in the genus Symphysodon.

It belongs to the cichlid family and currently comprises two species and three subspecies. It is endemic to South America, where it can be found in rivers in the Amazon basin, in Brazil, Peru and Colombia.

Its main characteristics are its colors and the discoid shape of its body. It lives in schools and feeds on small crustaceans, larvae, insects and fruits in its natural habitat.

It reaches an average of 15 to 18 centimeters in length and inhabits small lakes and streams with calm, clear waters. The discus is one of the most popular freshwater fish in the world for its varied colors and its long dorsal and tail fin. It is an ornamental and extremely peaceful species, being suitable to be raised with fish with the same temperament; however, it is very demanding with regard to water quality, so it cannot always be kept in aquariums with many different species.

taxonomy

The discus belongs to the Heroini tribe, of the Cichlidae family, in the order Perciformes, which is still little studied. It was described by the Austrian zoologist Johann Jakob Heckel in 1840 as Symphysodon. The exact phylogenetic position of this genus among the others belonging to the Heroini tribe is unknown. The type species of this genus is Symphysodon discus.

The specific name Discus refers to its discoid form, while its generic name, Symphysodon, is a Greek word. Symphys means growing in groups and odon means teeth, referring to their reduced dentition relative to other cichlids.

The genus includes only two species: Symphysodon discus (Disco-Heckel) and Symphysodon aequifasciatus (Disco-blue-brown), but recent studies carried out with their DNA have shown the possible existence of a third species, named by scientists as Symphysodon tarzoo; however the analyzes were not conclusive. The acceptance of this species is still being studied by researchers.

Subspecies

Three subspecies are currently recognized, based on genetic analysis. All were described by the American ichthyologist Leonard Peter Schultz in 1960, after the description of Pelegrin Franganillo-Balboa of the species Symphysodon aequifasciatus in 1904:

Symphysodon aequifasciatus axelrodi – Brown discus mite: It has a yellowish-brown body and a head with bluish streaks.
Symphysodon aequifasciatus haraldi – Blue discus mite: It has a light brown body, with strong blue streaks on the head, back and fins.
Symphysodon aequifasciatus aequifasciatus – Green Discus Acara: It has a blue-green body, with striking blue streaks on the head, back and fins.

Geographical distribution and habitat

The discus is native to the Amazon, but it can only be found in some countries in South America. The Heckel disc is found in the eastern part of the Amazon, mainly in the Nhamundá, Branco, Negro, Purus, Abacaxis and rivers Trumpets. The green disk has a restricted distribution to the western part of the Amazon, in the Japurá, Içá and Nanay rivers. The brown-disk and blue-disk subspecies are generally found in the Solimões, Amazon, Urubu, Juruá, Tefé, Coari, Uatumã, Trombetas, Tapajós, Jari and Tocantins rivers. The blue-brown disk can be found in the beds of Amazon rivers and in some hydrographic basins in Colombia and Peru, with a wider distribution of the genus.

They inhabit rivers with calm, shallow and clear waters, with abundant aquatic vegetation, submerged trunks and roots, being slightly warm, with acidic characteristics and low hardness. They live mainly in floodplain lakes and marginal lakes.

behavior and reproduction

The discus has a territorial behavior and does not carry out reproductive migrations. During the rainy season, they live alone or in small groups in deep water, but during the dry season they form large schools near fallen trees along the banks of the lakes.

It reaches sexual maturity at twelve months of age and spawns more than once a year, with about 1,500 eggs per spawn. At the time of reproduction, they form couples through sexual courtship, characteristic of cichlids. They usually lay eggs on large leaves or stones. During spawning, the female lays a small amount of eggs that will soon be fertilized by the male. pair maintains constant agitation of the water around them, fanning them with their fins, to ensure the necessary oxygenation. Then the parents are committed to cleaning them and keeping them safe until the larvae hatch.

Depending on the water temperature, the eggs hatch after two or five days and remain with the yolk sac for another three or four days, until they can swim freely. After hatching, the larvae are fed mucus released by their parents for two weeks. After this period, they can be fed with brine shrimp, but they will need their parents’ secretion for another thirty days. With approximately fifty days, they can be separated from adults.

Characteristics

The discus is generally referred to as The King of Aquarius. It is considered a small fish, reaching 15 centimeters in length. It has a laterally flattened body with a relatively long dorsal and caudal fin, which contribute to the discoid shape of its body. It has only one nasal orifice on each side of the nostril, a prostatic mouth and thick lips. Males are larger, more colorful and with the first dorsal fin rays thicker and longer. They do not have evident sexual dimorphism.

Their colors vary depending on the species and may have red, blue, green, brown, white and yellow tones, and currently there are about 600 variations. They have several rows of scales at the base of the dorsal and caudal fins, generally blue streaks throughout the body and eight to nine dark transversal bands over the body.

Threats / Diseases

Like many other fish, the discus is susceptible to infections such as parasites, mycoses, bacteriosis, viruses and even ectoparasites.
However, under natural conditions the infectious agents that infest them are not numerous enough to affect the health of the host, because the nutritional and physiological state of the fish is properly adjusted to the environment. Specifically for the discus, the following parasites are found : protozoa (Piscinoodinium pillulare, Ichthyophthirius multifillis, Costia necatrix, Trichodina), monogenetic metazoans (Dactylogyrus vastator and Gyrodactylus elegans), mycoses and bacterioses.

In captivity, four diseases attack the species more frequently, as well as other species:

Gastroenteritis: by Aeromonas hydrophila a gram-negative bacterium.
Hexamitosis: caused by protozoa such as Hexamita meleagridis and Hexamita symphysodonis.
Capillariasis: caused by the nematodes Capillaria pterophylli. It usually affects species belonging to the cichlid family.
Ichthyouris Infestation: Caused by parasites. Affects fish intestines.

Extinction risk

Despite not being on the IUCN Red List, the number of discus in the wild has declined on a large scale since the 1990s. for breeding in aquariums. Other factors of anthropogenic influence that contribute to the disappearance of the species is gold mining, which releases mercury into the water, deforestation and forest fires, as they increase the temperature of the region and prevent the formation of clouds, extending the dry period.

captive breeding

Discus discus bred in an aquarium.
The first discus bred in captivity date back to 1933. They were captured in the wild and died shortly after being introduced to the aquarium. It was from 1935 onwards that the first reports of specimens that reproduced in captivity and reached adulthood appeared. During this period, they were exported in small quantities to Europe and the United States. Larger exports took place after the end of World War II, when motorsports developed. However, it was only in the 1980s that a systematic activity of discus exploration began.

It is one of the most popular species in the world used for fishkeeping, as well as one of the most explored. However, they are very demanding about the conditions in which they live, and it is not advisable to maintain them by aquarists who have not yet mastered the control of the water parameters of their aquariums. They should be kept in large aquariums with a minimum of 20 liters for each specimen, in order to avoid territorial disputes. They are very sensitive in relation to water quality and prefer acidic pH water, around 4.2 and 6.2 and with a temperature around of 26 and 30°C.

As they are found in rivers with abundant aquatic vegetation and poor lighting, aquariums should have plants, decorated with logs and stones, and placed in low light places, to resemble their natural habitat. However, not all plants adapt to water temperature and low lighting, with some of the most suitable being the Pygmy Chain Swords (Echinodorus tenellus) and the Java Fern (Microsorium pteropus).

They should not be bred with aggressive species or species that eat quickly, as they can be attacked or end up not eating. They should be kept with fish with a temperament equal to yours and that are adapted to the same quality of water. The most suitable species are neons (Paracheirodon innesi), some species of tetras (Characidae), such as the cardinal tetra (Paracheirodon axelrodi), catfish (Siluriformes) and some cichlids (Cichlidae). They accept live and frozen foods well, as well as industrialized flake feed.

Apistogrammas derive their common name from the name of the region in which they were first identified or the first person to officially describe them (then cacatuoides, agassizzi, Borelli, Nijsseni, Panduro, and so on).

Behavior

These little cichlids will roam around the pond, they like to hide occasionally, so provide lots of plants and caves.

Maximum Size and Longevity

The maximum size of Apistogrammas varies depending on species.

On average, females can vary between 2.5 cm and 5 cm at most. Males range from 5 cm to 7 cm at most.

The average lifespan of Apistogramma is about 5 to 8 years if kept happy and healthy and in good water.

Water quality

Apistogrammas live naturally in soft acidic water, use this as a guideline when defining an Apistogramma as fauna for your aquarium.

Aquarium

pH: 5.5 – 7.0

GH: 30 – 100 ppm

Temperature: 24°C – 28°C

food

Apistogrammas are omnivorous and accept a wide variety of foods, including commercial foods such as flakes and bits.

Apistogrammas feed mainly from the top of the tank.

Compatibility

Apistogrammas can become quite aggressive when they are breeding, but most of the time they will be peaceful.

They are best kept with other small cichlids like South American Dwarf Cichlids, and can sometimes be kept with Discus and larger Tetras due to their water requirements.

Colors and Varieties

There are many different types of Apistogrammas, which come in many different colors and shapes. Some Apistogrammas that are commonly available include agassizzi, Borelli, cacatuoides, panduro, nijsseni.

Sex

Apistogrammas are very easy to differentiate between sexes, males have many brighter colors than females, their fins are longer and grow slightly larger and thinner than females.

Females are smaller and fatter in the belly area and have shorter fins. Females are mostly in shades of brown, silver or gray, with black highlights and bars. However, when they start to reproduce, they sometimes mimic male coloring and become brighter and more colorful.

General information

With “Nano Tanks” becoming more and more popular these fish are also becoming popular.

They don’t need a lot of water as they are very small, peaceful cichlids.

pH: min: 6.8 max: 7.4

Temperature: min: 24° max: 28°

Hardness: min:4 max:8

Maximum Size: 6 cm

Sociability: Males are very territorial for this reason you can only have one male per aquarium, females are also territorial but they can keep together.

Maintenance: Easy

Aquarium Zone: Surface and half aquarium.

Food: Omnivore. Live food, specific feed, larvae, brine shrimp.

Characteristics: This fish has the particularity of breathing atmospheric air thanks to organs called labyrinths that make the air pass very close to the bloodstream, providing the exchange of oxygen with the blood through diffusion.

Reproduction: Oviparous, males defend their territory formed around a bubble nest that they build and defend. The females “visit” the males who court them until they release the eggs, then and after fertilization the males place the eggs in the nest and expel the female from the territory. The hatch takes between 24 to 48 hours.

Sexual Dimorphism: Males usually have longer fins than females, the exception is the Plakat male that is confused with a female as it does not have as long fins as other males.

Scientific name(s): Astronotus ocellatus

Family: Cichlid

pH: 6.5 – 7.2

Temperature: Does not tolerate cold water. Ideal 22 – 25 °C

Sexual Dysmorphism: Few differences. Males a little bigger and more colorful as adults.

Food: Omnivore

Reproduction: Oviparous

Geographic origin: South America

The Oscar Fish is one of the several types of Acará Fish that exist. It is a fish of the Cichlid family and its scientific name is Astronotus Ocellatus.

Types of Oscar Fish: There are several types of Oscar fish like Oscar albino, Oscar albino pink, Oscar albino red, Oscar albino red tiger, Oscar black, Oscar tiger, Oscar bronze and the Oscar veil.

Care: Oscar Fish is fast growing and widely used in aquarium fish. In nature, its geographical distribution is in the Amazon basin and dams in the Northeast and Southeast. Oscar fish prefers a slightly acidic pH, between 6.5 and 6.8.

When raised in aquariums, partial water changes (20%) should be done more often in summer than in winter. The temperature must be between 21 and 26°C, at lower temperatures Oscar can stop feeding.

Oscar needs 12 hours of dark and 12 hours of light. At night, when at rest, he is almost lying down. Aquariums of 100 to 200 liters are needed for an adult individual and the aquarium must always be covered, as Oscar fish easily jumps out of the aquarium. It has dark coloring and mosaic designs when young and as it grows it gains light and dark patches of grayish green and orange. On the caudal fin there is an ocellus, a dark circular spot surrounded by a bright orange.

His hobby is tinkering with the decoration of the aquarium, even managing to take large stones from one corner to another, turning over the substrate and pulling out plants. There are reports of Oscar who eat from the keeper’s hand, let him caress his back, so they are very nice and sweet fish when used to their owner!

Reproduction: The ideal for reproduction of the Oscar is an aquarium between 200 and 250 liters. The water should be around 28°C.

There is a big stir in the aquarium before mating, and so-called ‘mouth games’ happen, which are a test of strength, where male and female face each other with their mouths wide open. After a few battles and biting each other, the couple move away from the other fish in the aquarium. A tile is placed facing downwards so that they prepare the place for spawning, the female lays the eggs in a circular motion while the male fertilizes them between 800 and 2,000 eggs.

After spawning, there is a great agitation in the water caused by the fish, with their fins, to oxygenate the eggs, and as a defense and protection against the attack of fungi and bacteria. After 3 or 4 days the eggs will hatch. The male then transports the fingerlings in his mouth to holes he makes in the substrate, taking care of them until they can swim on their own.

In the first days the fingerlings feed on the yolk sac. When this is finished, it is necessary to provide food such as beef pates, liver and non-fat fish, microworms and newly hatched brine shrimp. They should be fed every two hours in moderation.

For adults there are specific foods for carnivores, they also like small fish, heart and liver in small pieces. Vitamin ¨E¨ is essential in your diet, for its good development and good reproduction.

Always remember to have good filtration in the aquarium.
