Care Guide

Diet

Feed high-quality micro pellets, small frozen foods like brine shrimp and daphnia, and occasional vegetable matter. Feed small amounts 2-3 times daily, only what can be consumed in a few minutes. These tiny cichlids have small mouths and require appropriately sized food.

Behavior

Brevis are highly territorial and will aggressively defend their chosen shell homes, especially during breeding. They are active foragers that spend much time sifting substrate and exploring their territory. Males are more aggressive than females and will chase intruders away from their shells.

Breeding

Breeding is relatively easy in proper conditions with shells and stable water parameters. Pairs will occupy shells and lay eggs inside, with both parents guarding the brood fiercely. Fry emerge from the shell after 2-3 weeks and can be fed infusoria and micro foods.
