hey! I have 1 lamb chop rasbora and 5 harlequinns. I thought that the lc was just a bully, but I think he is just really horney. Lol. He was chasing the females, and bullying the males. Is there a way for me to stop the aggression? Also, I noticed him chasing and wrapping his tail around the female who is gravid. They were shimmying around together upside down on the bottom of leaves. This is sex, right? Or is it laying eggs? Will it really produce fertile Fish? Is this normal? Thanks.
