Blue Panchax Killifish (Aplocheilus panchax) is a surface-dwelling killifish with a sleek body shape and reflective blue tone. Aplocheilus panchax is best kept in a covered planted aquarium where floating plants, calm surface water and protein-rich foods bring out natural behaviour.

Quick facts

Scientific name	Aplocheilus panchax
Adult size	8-9 cm
Minimum aquarium	80 litres or more, with a tight cover
Temperature	22-26 C
pH	6.5-7.8
Temperament	Peaceful with similar-sized fish, predatory toward tiny fry or shrimplets
Diet	Small carnivore pellets, frozen foods, insect larvae and live foods

Care and setup

A tight lid is essential because panchax are confident jumpers. Use an 80 litre or larger aquarium with floating cover, gentle to moderate filtration and open lanes at the surface. Dark substrate and plants help the fish settle and show better colour.

Feeding

Blue Panchax are carnivorous surface feeders. Offer small carnivore pellets, frozen bloodworm, daphnia, brine shrimp and occasional live foods. They may take tiny fry or shrimplets, so they are not a safe choice for shrimp-breeding displays.

Compatibility

Choose calm tank mates that occupy the middle or lower levels, such as peaceful rasboras, small tetras and Corydoras. Related killifish to compare include Panchax Lineatus Gold, Panchax Lineatus, Australe Lyretail Panchax and Clown Killifish. Avoid very small top-dwellers and long-finned fish that may be stressed.
