My spotted leopard was put in with a Avacado (or Common) Puffer(long story) for a little over 24 hrs and the Avacado just ate up his tail fin. "Jaws, Jr." has been removed, but what should I do for the spotted leopard? He (or she) seems to be swimming around fine, but that fin looks terrible. Will it eventually grow back? Should I do anything special (like any meds or anything) for it? Any suggestions are appreciated.
