okk..this situation is a. starting to suck and b. a real pain in my neck....i will go dig out an extra tank from the garage attic...get some water mixing up and get that fish out. I am going to only treat this one fish at this point in time being that short amount of time that he has been in the tank. I will if it happens remove the rest of the fish if they show any signs of ich...
I am going to treat the fish with medication since he is going to be by himself in a bare tank....
I always wondered about proper tank tempature. I went scuba diving in the Cayman Islands last summer and the water temp was 86 degrees. I didn't see a single dead fish floating around. So, obviously 86 isn't too hot for them to live in the wild.
