When they grow to full maturity, approximately six inches or more, they will eat smaller fish. Surprisingly, they are probably the only ones of this species that have a somewhat peaceful disposition. They are best kept in small groups of four to six with other even-tempered fish such as neon tetras and black mollies. These placid fish require tall decorations (like plants), which they will stay quietly among. They cannot withstand extreme fluctuations in water quality and temperature. You should have a well-established aquarium and be experienced if you want to take the step towards keeping these fish.

However, angelfish are not for the beginner. The angelfish is certainly one of the most exotic and recognizable fish in all the community aquarium world.

Origin: Central Amazon to Peru, Ecuador.

It has a stouter body than the neon tetra. Two related tetra species include the cardinal tetra, Paracheirodon axelrodi, and the glowlight tetra, Hemigrammus erythrozonus. They will travel in schools peacefully throughout your aquarium.Īnother ideal community fish is the black neon tetra, Hyphessobrycon herbertaxelrodi. The iridescent coloration of this fish will glow if the tank is properly lighted. Like other mid-water fish, the neon tetra should be kept in a school of six or more individuals. They are capable of tolerating a wide range of temperatures, which makes them very desirable. Two of the main reasons for their popularity are their exciting colorings and their hardiness. The neon tetra is certainly one of the most popular fishes included in community aquariums. Egg-laying species of rasboras are not as easy to breed as the barbs, but they are extremely peaceful. They, too, are better off in groups of eight or more. Red-striped rasbora grows about an inch larger and has similar temperature preferences. The red rasbora has a deeper body than its close relative, the red-striped rasbora, Rasbora pauciperforata, which is streamlined in shape. This rasbora is another popular fish that is better off in a school of eight or more. Originally from Sri Lanka, the ruby barb also prefers warmer water and the company of other barbs. The ruby barb, Barbus nigrofasciatus, is also a peaceful addition to the tank in much the same way. Unlike the rosy barb, these Indonesian fish prefer warmer waters in the range of 68-79☏. It is recommended that schools contain both the more colorful males and the heavier females. But, if you keep them in schools of eight or more, they tend to establish a hierarchy within the school and will ignore the rest of the tank. They tend to be wild and disruptive, and even downright aggressive. Do not introduce these fish singly or by pairs. The tiger barb Barbus tetrazona is a related species. Barbs, however, can cause harm to smaller fish and to fish with ornate finnage. They are fast and agile and contribute great vitality to the mid-waters of the tank. Barbs get their name from the small barbels that act as sensory organs near and on their mouths. In cooler waters, it is generally more colorful. But it prefers cooler water than other community fish. The rosy barb is a very peaceful species that adapts well to a community aquarium.
