Space requirements

At least a 45×30 cm base, with planted cover and open access.

Diet and feeding

Offer varied, suitably small live or frozen animal foods. Some fish accept flakes.

Compatibility limits

Consider body size, pursuit and feeding competition.

Aquarium environment

Use plants and floating cover to break sightlines while keeping feeding access.
