After having a possible ich case with one of my clowns, I now have a qt set up and ready to go. I ofcourse cleaned it out after medicating my clowns...My question iss about incoming fish. I know people say to quarantine their new fish for 2-4 weeks, but I was wondering if there is a standard treatment (other than watching for disease) that can be done. I know medicating with no diagnosis isnt good for the fish, but are there some ways to get rid of common problems with out having to wait for visible signs?
