Alternative names

Dwarf Livebearer, Least Killifish

Sexing

Males exhibit a gonopodium while mature females are larger and fuller in the belly.

Breeding

These are active livebearers and will give birth to live fully formed fry after approximately 4 weeks of gestation. Females may spread out the process of giving birth over several days. They will not eat their own fry and do not need much encouragement to breed. A good alternative to Endlers and Guppys.

Tank compatibility

A very small and peaceful fish that can only be kept with equally small non-predatory fish. Due to their size, species tanks are better suited. Keep these fish in the ratio of one male per two-three females.

Diet

An unfussy eater which will accept many small foods such as micro pellets and flake as well as baby brine shrimp and daphnia.

Feeding regime

Feed once or twice a day in small amounts.

Environment Specifics

This fish appreciates very dense vegetation as this simulates their wild environment. They will tolerate both fresh and brackish water. Often kept in heavily planted unfiltered environments, even jars, it's recommended they're really kept in proper heated and filtered tanks albeit they can be kept in as small as 11.4 Litres (3 US G.).

Behaviour

A docile, curious peaceful little fish.

Identification

A tiny fish with a pale iridescent body with hints of blue and a dark lateral line. Fins are small and rounded with small dark spots at the base of each fin except pectoral. Dark vertical bands on the caudal half of the body are sometimes seen.
