So I have discovered one of my tangs has ich and I now believe my Coral beauty, & Flame fin tang are developing it as well.. My tank is over 120g, has tons of rock and lots of fish, so I’m really at a complete stand still on what to do. I’ve tried catching my tangs, and it’s just literally not possible. If I get a trap and try to catch them, it will take days/weeks to get them all. Am I going to have to basically break the tank down in order to catch these guys? It’s also a pretty heavily planted reef tank, so treating with corals isn’t really an option. Seems like my options are start taking rock & water out to catch, or let it be and hope for the best. I can’t watch my fish, some that I’ve had for years, slowly suffer though. Any advice on what to do and make this process a little less stressful
