The fish are very vibrant, especially the males with their striking blue and red patterns. I’ve kept them in a 10-gallon tank with proper temperature and pH control. They’re active and need a well-maintained setup. I plan to collect and store eggs for future breeding.

Beautiful fish with strong coloration. They do require a lot of attention to their life cycle and feeding. I’m new to killifish but have learned a lot from this species. The tank setup is simple but must be stable.

Highly recommended for experienced aquarists. The color is stunning and the fish are hardy once the environment is set. I’ve successfully raised eggs and plan to expand the population.
