The purpose of an egg tumbler is to allow fresh water to circulate over African cichlid eggs that have been separated from the parents. A fresh supply of clean water allows the eggs to develop in an oxygen rich environment where mold and fungus development is suppressed without the need for chemicals.

 

Egg tumblers are used frequently by Cyphotilapia frontosa breeders. The egg tumbler design allows for the gentle rolling action caused by these tumblers can simulate the normal incubation of these fish. Some hobbyists elect to go with a DIY fish egg tumbler but it’s not worth the time and head ache. Why spend the time searching for how to make a egg tumbler when you can order a ready made Egg tumbler for cichlids for a nominal amount of money and spend your time focusing on breeding your cichlids.

 

Check the video below to see how one Cyphotilapia frontosa Burundi breeder maintains multiple African cichlid egg tumblers in same tank as fish are breeding in to provide identical water conditions during incubation period. Alternatively this can be used on other non-adhesive fish eggs as well to help prevent fungus.
