The same goes for the platy. I have a male black platy that goes after a goldust female but leaves the rainbow female alone. He's harassing her so much that I'm considering getting another female or just getting rid of him.
Anyone else notice anything like this? All the fish are healthy so it's not that.
It's always best to have several females for every male. This way, one female isn't exhausted from all the attention. The males are acting normally. Adding females is preferable, but you can also introduce some floating plants to help make all the fish more comfortable. Water sprite, Dwarf water lettuce, Anacharis and Hornwort will all work well to provide hiding places for the female and the fry. Just drop some individual plants into the tank.
