About

Nothobranchius kirki inhabits temporary seasonal pools in southern Mozambique and adjacent areas. Males are adorned with vivid red spots scattered across a bright blue body, and the unpaired fins are edged in red and black. It is a moderately robust annual species that adapts reasonably well to captivity as long as the keeper provides proper peat substrate for spawning and manages the dry incubation period correctly.

Care Guide

Water: 20–26 °C, pH 6.0–7.5, soft to moderately hard. Tank: 30 L species tank; peat or coconut substrate; tightly fitted lid essential. Feeding: Live Daphnia, Artemia nauplii, blood worm; micro-pellets as supplement. Behaviour: Males fight; maintain as a trio (one male, two females) per tank. Compatibility: Species tank strongly recommended.
