well, first off, lower the temp back down to 80... higher temperatures can help with ich, but just as it can kill your ich, it will also kill your clown. that would be my guess as to why he is breathing so fast, not that the ich has gotten onto his gills. lower it back down and try treating with hypo. remove all yoru inverts (a FEW hermits could survive, but not always the case, snails, corals, shrimps, crabs, etc) and lower the salinity to 1.009 over the courseof 2 days or so. leave itlikethat for at least a week. or you can buy a hospital tank anddo the same thing only leave the clown in therefor 6 weeks.
