This killifish adds vibrant colour to the tank. I’ve managed the dry incubation cycle successfully and saw healthy fry emerge. Requires some knowledge of breeding, but rewarding.

The fish are active and display interesting behaviours. I kept them in a 10-gallon tank with proper substrate and lighting. Breeding was a bit tricky at first, but once I learned the dry phase, it worked well.

It’s a unique species with striking appearance. I found the breeding process challenging and needed to research the incubation steps carefully. Not for beginners.
