I did something stupid. Hope someone can help. I came home and somehow one betta tank (I have 8) had temp of 94! I got so worried, even though the betta seemed just fine, that I immediately took out enough water and adjusted temp to 84, where I normally keep it. I have maintained bettas for a year or so at this temp, no issues. BTW, the tank did not even have a heater in it. Well, when the fish reacted to the 84 temp, he freaked. He was hiding behind the filter, swimming erratically, flaring, and didnt want to eat. I set up a small tank with 92 water, and he's in there now. Seems better, more calm, still not interested in eating. Will he survive the night??? I feel awful. Any suggestions of what I should do further?
