Hi all,
I just thought I would throw this out there for discussion.
I have read that the temperature of the breeding tank can affect the eggs of some Apistogrammas and determine whether the fry are predominantly Male of Female.
I have had two batchs of Melanochromis Johanni cichlids and the first batch was around a 50/50 mix but the second batch , bred in a slightly higher temp, seems to be mostly Male 70/30.
What are your experiences in this? With cichlids or any other fish.
