Tetras
Black phantom tetra Hyphessobrycon megalopterus Hyphessobrycon megalopterus.jpg 4.5 (1.75") Community Easy the black phantom tetra enjoy being in groups of 6 or more and a slightly shaded tank. Males may claim small territories and occasionally minor battles may occur. The Phantom tetra goes well with other tetras of similar size. They also prefer floating plants.
Black neon tetra Hyphessobrycon herbertaxelrodi Black neon tetra.jpg 4 (1.6") Community Intermediate this fish is similar to the neon tetra other than coloration.
Black tetra Gymnocorymbus ternetzi BlackTetras.JPG 5 (2") Community Easy a highly spirited fish that may occasionally chase its own species as well as harass slow moving fish with long fins. This fish is very hardy and can stand a variety of water qualities. Disease is not a big problem with the black tetra. The black tetra is also known as the black skirt tetra. The female black tetra is more robust and larger than the male.
Bleeding heart tetra Hyphessobrycon erythrostigma Kirschflecksalmler-W.jpg 6.5 (2.5") Community Intermediate the bleeding heart tetra is distinguished by the small red spot on both sides of the fish. This fish is very prone to diseases, and can grow larger than most tetra species. It is not recommended for beginners.

Cardinal tetra Paracheirodon axelrodi Paracheirodon cardinalis.JPG 5 (2") Community
Cave tetra, blind tetra Astyanax mexicanus Astyanax mexicanus.jpg 12 (4.7") Easy cave tetra is the blind cave form of the Mexican tetra. The blind cave tetra is easy to care for and is hardy. The fish is born with eyes, but they quickly deteriorate leaving behind two scars where the eyes once were. The blind tetra needs to be in a shoal in order to show peaceful behavior, and to prevent fin nipping. Despite their lack of eyes, the blind cave tetra can easily avoid other fish and obstacles in the tank. This tetra prefers low to moderate lighting.
Congo tetra, Lufundi (native name) Phenacogrammus interruptus Phenacogrammus interruptus (aka).jpg 7.5 (3") Community Intermediate Sufficiently peaceful for home aquariums, though it may bite fishes smaller than its size. It is more comfortable in indirect light. Over-head lighting is preferred and under no circumstances should light be directed at the front or rear glass.

Neon tetra Paracheirodon innesi Neonka obecna paracheirodon innesi.jpg 3.75 (1.6") Community Easy the neon tetra is sensitive towards water quality and is susceptible to many freshwater diseases. However, the fish is very peaceful and will not attack another member of the tank. Females are larger than the males. Due to their small size, the neon tetra should not be kept with large fish. Neon tetras are also very delicate and any harassment they may receive can result in death. This can be prevented by putting them with other small community fish or fish known to ignore their tankmates. The neon tetra feels the most comfortable when in groups.
Penguin tetra, blackline penguinfish Thayeria boehlkei 6.5 (2.5")
Rummy-nose tetra Hemigrammus rhodostomus Brilliant rummy nose.jpg 5 (2") Community Intermediate
Serpae tetra Hyphessobrycon serpae Serpae tetra.JPG 4.5 (1.75") Community Easy this fish may nip the fins of slow moving fish or fish smaller than it. It is best put with other large tetras or with fish of similar size or larger.
Hatchetfish
Common hatchetfish Gasteropelecus sternicla
Silver hatchetfish Gasteropelecus levis
Marbled hatchetfish Carnegiella strigata Carnegiella strigata.jpg 5 (2") Community Intermediate Peaceful and dwells at the top of the tank in schools. Rarely breeds in captivity. This powerful leaper can easily jump out of an aquarium, so keep only in a fully-covered tank.
Black-winged hatchetfish Carnegiella marthae Carnegiella marthae.jpg 4 (1.5") Community Intermediate Peaceful and dwells at the top of the tank in schools. The most hardy of all the hatchetfish, but not the most plentiful. Does not breed in captivity. This powerful leaper can easily jump out of an aquarium, so keep only in a fully-covered tank.

Silver dollar Metynnis argenteus Silver dollar fish Metynnis argenteus.jpg 15 (6") The name "silver dollar" may also refer to Metynnis hypsauchen, Metynnis maculatus, or other related fishes. It will chew and eat plants.
Red bellied pacu Colossoma bidens 120 (48") Difficult the red bellied pacu is a close relative of the piranhas, but without the sharp teeth and the aggression. However, care should be taken if interacting physically with the pacu as their powerful jaws can crush human bone. The Pacu is a peaceful fish that requires at least a 750 litre (200 gallon) tank when fully mature. It is omnivorous and can be put with large cichlids, but avoid smaller fish. Despite their similar appearance to piranhas, the pacu is not suited to eat meat very well, as their natural diet of nuts suggests. Be aware that this fish can grow to 1.2 metres (four feet) and the owner must be prepared to house them in a very large tank if they wish to keep the fish (750 l/200 gal minimum). Also be aware that this fish grows very fast, and can grow as much as one foot in the first year.

Angelfish Pterophyllum scalare Freshwater angelfish biodome.jpg 15 (6") Intermediate several color varieties; this species is the common angelfish in the aquarium trade. Angelfish can grow up to fifteen centimetres (six inches), and therefore should be housed in a large aquarium. Angelfish should be kept alone, or kept with three or more. This is because that if two are kept together, the larger fish will pick on the smaller fish. Angelfish are not as hardy as other cichlids and should not be kept with small fish such as neon tetras. However, just the opposite is true: Angelfish should not be kept with fish that may nip and annoy it such as some large tetras.

Chocolate cichlid Hypselecara temporalis
Oscar Astronotus ocellatus Astronotus ocellatus.jpg 45 (18") has different varieties including long-fin, albino, golden, etc. The oscar cichlid is fast growing and can grow to a very large size when mature, and therefore should be housed in a large aquarium. The oscar can be messy to look after as they love to dig up plants and scoop up rocks. The oscar should be put with fish of similar size as they will eat any fish that can fit in their mouth. The oscar prefers to be with members of its own species, but this is not a necessity for its well being. The oscar is one of the more hardy cichlids, and can be put with other large cichlids, pacus, large plecos, large sharks, and other large fish.

Siamese fighting fish Betta splendens Kampffisch betta splendenscele4.jpg 7.5 (3") Numerous color and fin pattern varieties. In the U.S., the fish is often called "betta", although this word is actually the name of the genus that includes more than 60 species other than the Siamese fighting fish. Multiple males in a tank will result in conflicts and possibly death. Females can be housed together in groups of 4+ in a tank, though they may become territorial and attack each other. Males have long flowing fins with vibrant colors, and females have shorter fins. This fish is best put with fish that do not nip fins, as the fins of the betta are easy to attack. They should also not be housed with other fish with long, flowing fins as the Betta may confuse it with another, and attack.

Chinese high fin banded shark Myxocyprinus asiaticus 90+ (36"+) Goldfish/Large Pond Difficult the highfin shark is a truly unique fish. At youth, the shark has a high dorsal fin, a plump body, and radiant colors. However, as the fish matures, the characteristics of the fish changes drastically. The dorsal fin becomes shorter, the fish achieves a more cylindrical shape, and the color fades to a dark brown. The fish is not suitable for fish tanks because of the size it can grow to. The highfin cannot be housed with tropical fish due to their lower temperature preferences. The highfin prefers to be in a school, so more than one should be housed together. The "shark" is a peaceful fish, and will not openly attack others. Highfins are bottom dwellers and omnivorous. They will eat invertebrates and scrape algae off rocks.
