 Red tail shark (Epalzeorhynchos bicolor; syn. Labeo bicolor) is a carp species in Cyprinidae family. It’s quite unusual and not demanding fish that attracts attention with its rare body coloring – contrasting combination of almost black and red colors.

To keep Red-tailed black shark you’ll need a tank capacity starting from 200 liters.

However, it’s recommended to recreate natural habitat in a tank, i.e. a fast flowing river with bottom substrate of different size.

You may use gravel, stones and pebbles as a tank substrate and also put some tree roots and braches into the tank as well as water plants of Microsorum, Bolbitis or Anubias kind, which can stick to tank decorations.

Bright light will ensure active growth of algae, which is necessary for diet. Just like other species that inhabit in fast rivers the fish can’t stand accumulation of organic precipitate in the tank, since the fish prefers clean water with high oxygen content and moderate stirring.
