I had a school of rummynose and all but 1 died. I really don't want to try them anymore, I went through so many tetras, and they brought ick into my tank and all sorts of other stuff so I'm just asking if my surviving rummynose will be ok on his own? There are serpae tetras in the tank will he try to school with them? I'm thinking of eventually getting a tank just for rummies and then I'll try getting a school of rummies again, but it doesn't look like that can happen anytime soon. Any input is appreciated!!!
