Convict cichlid eggs take approximately three days to hatch. The fry should be swimming free after another 3 to 5 days. The tank temperature should be around 76 degrees Fahrenheit to encourage hatching.Continue Reading
Convict cichlids are relatively easy to breed, with both parents guarding the eggs until hatched. Because parents can become extremely aggressive during this time, you should consider keeping them in their own breeding tank.
After the eggs hatch, the fry take up to 5 days to absorb their egg sacks and begin exploring under the watchful eyes of their parents. A single spawn can yield 100 to 200 fry, and you can expect another brood within the next month. In community tanks, few of the fry survive to adulthood.Learn more about Zoology
