Karin15,
You say "no rants" etc, and this is not a rant. But.. if there is a fish that is biting other fish, then you have a compatibility problem. Yes you do need to know how to heal the fish (as miss wiggle has offered advice), but you also need to sort out the problem as to why the fish are getting hurt. You say he's not being bullied, but i doubt he thinks the same with his tail missing

he isn't, its just my gourami he randomly bites my fish, I think i'm going to give him to the pet store.
Sounds like a plan
