Yellow-tailed Congo tetra

Alestopetersius caudalis

Yellow tail lobes surround a dark central extension

An adult male has extended fins with pale ends; females tend to be plainer with shorter fins.

Native range: Native to the middle and lower Congo system, including Lake Tumba and tributaries such as the Ruki and Ubangi.

Active and easily startled; male rivalry can cause injury when space is inadequate.

Appearance and identification

The yellow tail with a dark centre sets it apart from the iridescent Congo tetra.

Keep eight to ten of mixed sexes.

Provide a 120 × 30 cm base with swimming space and retreats.

Combine small frozen or live foods with dry foods including plant ingredients.

Check companion size and behaviour.

Use patches of plants and wood while leaving open water.
