Clown Killifish thrive in heavily planted aquariums with calm water, floating plants, and a secure lid, as they are natural jumpers.

🐠 Compatibility

Ideal for nano community aquariums. Best kept with other peaceful micro species such as small rasboras, pygmy Corydoras, shrimp, and snails. Avoid larger or fast-moving fish that may outcompete them for food.

Important Notes

Clown Killifish are surface dwellers and require a tight-fitting lid due to their jumping behaviour. They prefer stable, mature aquariums with gentle flow and plenty of cover at the surface.

The Clown Killifish is a perfect choice for UK aquarists looking for a tiny, beautifully patterned fish that adds colour, personality, and surface-level movement to nano and planted aquariums.
