Tetras are some of the most varied fish you will come across. From tiny, brightly colored Neon Tetras to the rounded Marble Hatchets, you'll find that there are a number of beautiful variations in just this species. Tetras tend to get along well with other fish of similar size, but can end up in danger if you tank them with more aggressive species.

These fish do best in larger groups, so you should make sure to have at least 6 in a tank, though they do well with more. Males can be somewhat territorial, but the majority of the tetras will form schools. They prefer plenty of open space to swim in as a group and do best in slightly acidic water, with a pH of around 6.5.

Feeding

Feeding this species is fairly simple as they will eat flakes. However, they particularly like baby brine shrimp, particularly during breeding, so be prepared to supplement the diet.

Breeding

When it comes to breeding tetras are not easy. You will need a separate tank where the male and female can be placed. The water should be fairly acidic, more so than the communal tank. Once the fish do breed, the eggs will simply be scattered about. The adults must be removed from the tank or they will devour the eggs. Baby fish can be fed freshly hatched brine shrimp once they hatch out. It can take a long time and many tries to get a successful breeding program going, even experienced fish breeders may have difficulties.

Tetras are beautiful fish and do well in community tanks, making them a great addition to any aquarium. While breeding can be difficult, they are simple to care for and feed.
