List of freshwater aquarium fish species
A vast number of aquatic species have successfully adapted to live in the freshwater aquarium. This list gives some examples of the most common species found in home aquariums
Angelfish
| Common name | Taxonomy | Life span | Level of aggression | About | Image | Size | Remarks | Temperature range | Ph range |
|---|---|---|---|---|---|---|---|---|---|
| Angelfish | 'Pterophyllum scalare | 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. They are good fish for beginners but only if you pay attention to their tankmates and temperaments. They work well with other fish but should be kept in a school of 3 or more if you want more than 1. | |||||||

| Cave tetra, blind tetra | Astyanax mexicanus |  | 12 cm (4.7 in) | The 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.

| Neon tetra | Paracheirodon innesi |  | 3.75 cm (1.48 in) | The neon tetra is sensitive towards water quality. Bred in captivity but often badly inbred, making them less hardy and susceptible to diseases. However, the fish is very peaceful and will not attack another member of the tank. Females are larger than males. Due to their small size, the neon tetra should not be kept with large or aggressive fish. The neon tetra is a schooling fish that feels most comfortable when in groups. | ||

| Splash tetra | Copella arnoldi |  | 5.5 cm (2.2 in) | Active, sensitive to water quality, prefers moving water. Lives near top of tank. Breeding pairs leap to deposit eggs on overhanging leaves; may jump out of uncovered tanks. A schooling species. | ||
| Serpae tetra | Hyphessobrycon serpae |  | 4.5 cm (1.8 in) | 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. | ||
| Silvertip tetra | Hasemania nana |  | 3 cm (1.2 in) | Silvertip tetras tend to be moderately aggressive and, because of their small size, should not be kept with large or aggressive fish. | ||

| Congo tetra | Phenacogrammus interruptus | .jpg) | 7.5 cm (3.0 in) | Sufficiently peaceful for larger (40 gal+) 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. | ||
| Jellybean tetra | Ladigesia roloffi |  | 3 cm (1.2 in) | Smaller even than the neon tetra. This mid west African schooling species is a favoured species for the nano-aquarium. | ||

| Common name | Taxonomy | Image | Size | Remarks | Temperature range | pH range |
|---|---|---|---|---|---|---|

| Marbled hatchetfish | Carnegiella strigata |  | 5 cm (2.0 in) | 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 |  | 4 cm (1.6 in) | 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. |
| Pencil fishes |
| Common name | Taxonomy | Image | Size | Remarks | Temperature range | pH range |
|---|---|---|---|---|---|---|
| Golden pencilfish | Nannostomus beckfordi |  | 6 cm (2.4 in) | Hardiest, easiest-care species of aquarium pencilfish. Populations vary in color and pattern. Like all pencilfish, it is timid, eats small foods, enjoys live/frozen foods, can be bred in captivity, and cannot compete with aggressive fish. Like all pencilfish, males may be aggressive with each other if the tank or the group of pencilfish is too small. | ||
| Hockeystick pencilfish | Nannostomus eques |  | 3.5 cm (1.4 in) | Naturally swims and rests at a 45-degree angle. | ||
| Barred pencilfish | Nannostomus espei |  | 3 cm (1.2 in) | Other pencilfish adopt this barred pattern while inactive at night; only N. espei has it at all times. | ||
| Dwarf pencilfish | Nannostomus marginatus |  | 2.5 cm (0.98 in) | Less aggressive with members of its own species than most pencilfish; males rarely spar. | ||
| Coral-red pencilfish | Nannostomus mortenthaleri |  | 3 cm (1.2 in) | More aggressive with members of its own species than most pencilfish. Keep in larger groups in larger tanks to diffuse aggression. | ||
| Nannostomus nigrotaeniatus |  | 3 cm (1.2 in) | ||||
| Three-lined pencilfish | Nannostomus trifasciatus |  | 3 cm (1.2 in) | Males defend small territories. Otherwise a peaceful species. | ||
| One-lined Pencilfish | Nannostomus unifasciatus |  | 4 cm (1.6 in) | Naturally swims and rests at a 45-degree angle. |
| Serrasalminae (pacus, piranhas, and silver dollars) |
| Common name | Taxonomy | Image | Size | Remarks | Temperature range | pH range |
|---|---|---|---|---|---|---|
| Silver dollar | Metynnis argenteus |  | 15 cm (5.9 in) | 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 cm (3.9 ft) | 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-liter (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 diets of nuts suggest. This fish can grow to 1.2 m (3.9 ft), so need a very large tank (750 l or 200 gal minimum). This fish grows very fast, and can grow as much as one foot in the first year. | 78–82 °F (26–28 °C) | |

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 male, and attack. Minimum tank size for one male or female and maybe a few shrimp or snails is 5 gallons. Minimum tank size for a female betta sorority is 20 gallons. | ||
