hi. so i need some help on first aid of fish. i bought some damsels from a LFS and this LFS has really bad quality of fish and staff dont know crap, but things are cheap. I bought 6 damsels for $10. I got 2 yellow damsels, spotted damsels, and blue damsels. One of yellow damsels seems to be having some red skin or red stuff on its skin. I was wondering if someone could tell me what this is? These damsels seems really small. I hope they don't die. They are in my 10 gl hopsital tank right now.
