Average success

Breeding Report: Cyprinodon macularius
Location code: macularius eremus 'Quitobaquito'
Water conditions: Very hard and alkaline, 20-23oC
Spawning Method: Long term (fry appear with adults)
Sex ratio: Roughly equal
Breeding difficulty: Average
Success: Average
Other Comments: Breeding occurs naturraly if you keep these fish in a shallow pond, stream or tub outside from mid april to mid october. I kept my fish in an articficial little creeklike stream (only 4 meters long, 40 cm width and 6 cm deep, using a waterpump to create a waterflow). Please prepare the pond or tub at least one month before releasing the fish in order to get 'life' in the water. Fry appears automatically when the weather warms up. Parents are not cannibalistic. Keeping and breeding them outside gives this species a better condition. I did not fed them. Food was present in abundance (mosquito's and their larvae and other insects). During the colder months the fish were transferred to a tank inside the house.
