I got a whole heap of convicts with the idea of finding a female to raise up to put in with my male albino convict. Any ways, out of 8 I got one pair.(cant believe my luck, all my cichlids end up male). I left them together and separated them from the others with a glass partition, leaving 2 on the other side. I've heard a male cichlid with nothing to defend can turn on the female. After 3 attempts at eggs, one lot hatching then disappearing, he hogs the nest area and she is up hiding behind the filter. Is this normal? Have they gone off each other?
