Serpae Tetras (hyphessobrycon callistus), is found in South America as well as other locations and lives in still water containing vegetation
The average adult grows to 4cm in length and they have a beautiful red bod, black dorsal fin and a small patch above the pectoral fin. The female will become larger and have a fuller body however the males are more colourful. This fish is an egg scaterer and breeding in the aquarium is not common.
Because of its dark red colour the serape tetra is a popular fish in the aquarium trade but it can nip at the fins of long finned fish. They prefer to be kept in large groups and are only aggressive if kept in small numbers. They will go well with other tetras in a community tank and because they are middle level swimmers the tank would benefit from bottom dwelling feeders to clean up any uneaten food.
The serape tetra will benefit from soft and acidic to neutral water, and a water temperature between 24-29 degrees centigrade.
