It does well in a well planted aquarium with slow to medium water movement and with plenty of swimming space. You can use sturdy plant species like Java fern which thrives without any special light. It will also help to control excessive algae growth because it competes for nutrients with the algae.

Many aquarists use a blue background in the aquarium to bring out the colors of their bloodfin tetras.

The aquarium should have some floating vegetation that provides shelter during swimming surface level of the tank. The tank also should have a very tightly fitted cover that helps to prevent tetra during jumping.

It requires 10 gallons or larger aquarium for 6 or more tetras of same size.

Tetras are adapted to soft and slightly acidic water which is essential for breeding. The aquarium should have good water quality and suitable water temperature and pH that range from 64.5 – 82.5°F and 6-8 respectively.
