I have a 55 gallon freshwater tank. Until about an hour ago, a female silver molly was the only resident. I just purchased three creamcicle balloon-belly mollies and a black molly, all female, but the silver molly is bullying the most colorful creamcicle. If need be, I can probably re-home and replace the silver molly, but the most likely candidate for re-homing is possibly going to use her to feed his lionfish, which I don't particularly want, but I also can't have her killing everything. They were OK until feeding time, and I fed plenty- everyone got some- but the bullying began and seems to be focused on one balloon in particular. I can't go buying a bunch more supplies like mesh breeders and the like, and don't particularly feel like starting up the small iso tank I just dismantled. Help!
