had my 75 gal set up and thought i saw a few white dots on my dottyback so i put him in a 10gal with cupramine.i moved so i set up a 30 gallon and put a heater,bubbler and filter (no carbon)i have a hawkfish,two clowns and a lawnmower blenny.last night i saw the blenny swimming around rubbing himself on the few decorations i put in there.i put him in with the dottyback just in case of ich.now my question is should i quartine the 30 gallon ith the three fish in it for a precation?i would hate to infect my 75 gallon after i just set it up.
