I have been battling ICH for a second time both times the fire fish did not get or have any symptoms of having it. After treating the tank with reef safe products that didn't work (newbie) he again is the sole survivor. i want to keep the tank fallow for the 11 weeks to ensure i dont have this problem again but do i have to take him out while i do this and i also have a bunch of peppermint shrimp and some hermit crabs, can they stay in tank as well. So frustrated at this point any help would be appreciated...
