Scarlet Badis

A tiny, jewel-like fish from India, at about 2 cm, in which males are scarlet with blue bars. It is shy, males fight, and it usually eats only small live or frozen foods, so it suits a planted nano tank.

Check the scientific name when buying, as common names vary between sellers and countries.

Males are far more colourful, with larger fins. Females are usually plain.

A small, dark, densely planted tank with a tight lid suits most killifish, as they are strong jumpers. Filtration should be gentle.

A jewel-like small fish, with males displaying to rivals and to females.

Often kept as one male with several females, because males can fight.

Males can be quarrelsome with each other.

Best in a species tank, or with small, peaceful fish. Avoid fin nippers. It may eat baby shrimp. Choose its tankmates with care.

Fairly tolerant of different water, if it is clean and stable.

Prefers small live and frozen foods.

Feed small amounts, and remove anything left after a few minutes.

Lays its eggs on a cleaned surface, such as a stone, leaf or the bottom of the tank, and the parents may guard them. Move eggs or adults if you want to raise many fry.
