icthyophonus hoferi, anyone had this problem in their reef tank? Recently had a few floaters all with in a 4 day period. The yellow tang, still alive, definitely has bulging eyes which I diagnose to be hoferi so I assume this was the problem with the fis that died. All other fish (about 10) look fine. Could it be possible bad frozen food caused this? I added a cleaner wrasse and diamond goby a few weeks prior, both are fine and were quarantined for 30 days.
