Ask Finn

One of the largest and most colorful killifish species, native to West Africa, with males displaying stunning blue, yellow, and orange marbled patterning across the body and flowing fins. It is an annual killifish in the wild, reaching 4–5 inches; it is best kept as a pair or trio in a species tank and can be mildly aggressive toward other males.

Care Guide

Diet

Blue Gularis Killifish are carnivorous and require high-quality foods including frozen bloodworms, brine shrimp, and small live insects. Feed small portions once daily, offering only what they can consume in a few minutes. Supplement occasionally with quality carnivore pellets formulated for killifish.

Behavior

These are active, top-dwelling fish with semi-aggressive tendencies, especially males toward each other. Males display elaborate courtship behaviors with flared fins and vibrant coloration. They are best kept singly or as a bonded pair/trio, as multiple males will fight intensely.

Breeding

Breeding Blue Gularis in captivity is moderately difficult and requires species-specific setup. Provide fine-leaved plants like Java Moss or Riccia for egg deposition, maintain optimal water conditions, and separate pairs into dedicated breeding tanks. Fry are small and require infusoria or liquid fry food initially before graduating to micro foods.
