Silver Molly Is Bullying

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!

 

What are the sexes of the fish? Males tend to be more aggressive

 

They are new... give them a couple of days to see how it goes (unless you are seeing physical injury). Turn off the lights for 12-24 hours to help all residents calm down.

 

Als rearrange your decor so they don't have established territories.

 

Everyone is female. I rearranged decor a bit and they seem OK now. The silver one is kinda shunned by the rest, but at least nobody's being murdurized in there. Sorry- guess I overreacted. She killed her tank mate once before- I chalked it up to too small of an aquarium (I was pushing it a bit). Thanks!
