Hey david Move the catfish to a new tank..... then treat the existing tank..... shouldnt have any tag alongs with the catfish to the new tank..... just dont scrap the net along the tank wall or get any plants in it...... remove all that other stuff first before netting outting out the catfish... That should work fine then.... Fluke tabs is what i use also.... works great...
