Males and females need to be conditioned to breed, basically meaning plenty of live foods. My male and 2 females,(1 back up) are getting feed a variety of bloodworm, daphnia, brineshrimp and mosquito larvae.
My fish get fed this regulary but I have now seperated my 2 females from my community tank to make sure they are getting plenty themselves.
Once conditioned they should be nice and round and full of eggs
