Sat. 2/19 I noticed my betta lying up against the glass in his 2 1/2 gallon tank. I checked the temp. and sure enough it was 92! I did a 50% water change, with purifying drops, and got the temp back to 75 or so. He hasn't eaten in days, he stays at the bottom, or hides in his tunnel, with virtually no movement. He will move when I jiggle something in his tank, swim up to me and then just go right back down. He is a survivortoo! He has jumped out of his tank twice, before I put the screen on top of the tank and survived. Took a few days but he bounced back. Now I don't know? Any suggestions are welcome.
