Killifish (Various species) Aquarium Care Guide

Keeping Killifish (Various species) in an aquarium requires the right conditions.

Aquarium Information

• Care level: intermediate
• Temperament: peaceful
• Diet: carnivore
• Minimum tank size: 5-10 gallons (depending on species)
• Compatibility: Generally peaceful with other small, non-aggressive fish. Best kept in species-specific tanks or with other killifish. Avoid fin-nippers or overly boisterous tankmates.
• Special requirements: Many species require specific water parameters, live or frozen foods, and some (especially annuals) benefit from a substrate for egg-laying (e.g., peat moss). Some species are jumpers, so a tight-fitting lid is essential. Specific requirements vary greatly by species.
