No data available but assumed not different from its congeners. Breeding Cynolebias attenuatus is not for inexperienced hobbyists. The species becomes relative large and need special attention in feeding and storing the eggs. Food demand is high as the species need to grow to adulthood within a few months and eggs need to be stored under very cool circumstances in wich a frigidaire could become a good tool. Reproduction is best with one male and a number of big females. Tank need at least contain 60 liters and provide shelter for the females as male can be very agressive.

Also females are known to be agressive to each other. Put a high container filled with neutral pH material like Coco peat or clay (or a mix of it) for spawning.

Eggs are 2.2 mm in diameter and need about 4 to 5 months to develop. Juveniles that grow faster than others should be separated from the smaller ones immediately as they prey on them.

Remarks :

As with almost all other species this one is seldom available under hobbyists.
