Black Tetra

Black Tetra, also known as Black Skirt Tetra, Petticoat Tetra, High-fin Black Skirt Tetra, Black Widow Tetra, and Blackamoor, is a freshwater fish from the Characin family.

It’s originally found in south-central Brazil, Paraguay, and northeast Argentina. Some populations are also found in the upper Paraná and Paraíba do Sul Rivers.

This fish is commonly kept in aquariums. Black tetras are social fish that swim together in groups called schools.

They eat small crustaceans, insects, and worms. They’re active creatures and may chase other fish with long fins but are generally hardy and not prone to diseases.

Females are bigger than males, and they usually swim around the middle or upper water layers of an aquarium.

You should keep them in groups of five or more with at least a 60 cm long tank for their comfort.
