So I got ich in my 90 gallon and was waiting for new 210 to establish. While doing so tried to figure out best route to treat ich. After Steves advice I decided on tank transfer. Got all set up and decided I would start with 3 little fish for the first go. So I have a dartfish, mandarin, and blenny in first round of TT. Problem is while pulling all my rock to catch said fish my tang took a tragic turn. 1 day after he was listing and went belly up lastnight. I instantly tried to do the salinity a little and kicked the flow way way up. I thought he was a goner but after about an hour of being upside down he turned over and is very roughly and lethargic while swimming. Would it help him if I put a low dose of copper in the tank? I can pull all the rock again but wouldn't be able to get all the sand. Its him, 2 clowns, 2 darfish, and a radiant wrasse left in the tank. Only inverts are random snails, worms and pods. So if I put in cupramine in a low dose would it affect anything or crash the tank with the die off since no rock will be in there?
The TT fish are getting moved to tank 2 tomorrow morning. I really don't want to loose any fish. Please help
