Quarantine Tank For Rent?

As mentioned in the other thread, you need to determine what it is before you decide on if and how to treat it. Idelaly you need a pic for us to see. My clowns had little white fungus-like growths when I first got them, these cleared up once I fixed a few things and got them eating good food. If you have isopods, you need to deal with that, not treat a fish. Try to get a pic up.
