I am kind of worried about my female german blue ram. The male is much bigger than her and he chases her a lot. It has been about a month since their first breeding and i know he is trying to send signals but it seems like she isnt interested and she is really stressed. What should i do? Can rams breed once and not breed again? The only other fish in the tank are 2 electric blue rams but they dont seem to bother anybody. The big male is just very mean.
