So, I have this one angel, that is constantly picked on by every other fish in the tank,and she literally just does not know how to stand up for herself! She has almost completely lost her dorsal fin, so I went ahead and moved her into my small 20 gal. with a pearl gourami, a baby platy, baby molly, some white cloud minnows, and weird little yellow guy. I thought that she would be fine in there, and that the only fish that may possibly mess with her is the gourami. So, I go back up there and look in, and instead my baby platy is sitting there nipping her fins!! And she is veeerrry slowly swimming away, while he's sitting there taking chunks off her! I quickly scooped her out and put her in a refugium on the side of my tank. She's ok now, but I don't know what to do with her!! Do you think she will ever be able to stand up for herself? Or would I be better off just taking her back to the fish store, and getting an angel that can and will defend itself. The other one is fine, and chases the rosy barbs away, but she just lets them nip her!!
