Lets not get ahead of ourselves here. I have seen more than my fair share of ich and I have never seen ich that is this small nor in the sheer numbers. I am not positive but fairly certain it is velvet. I keep my display tank at 80 degrees. So your saying my fish are stressed due to this? From my understanding if anything it will speed up the life cycle of the parasite at higher temps. I am not just dumping garlic in the water either. I am adding heavy doses of it to his food. But I do agree if his eyes follow me then he is alert.
