heater malfunction & now betta's lethargic
Last Saturday, 2/19 I noticed Cutie Pie just lying up against the glass in the tank. It seemed like an effort to move. I checked his water temp, with a digital instead of the glass cheap one in his tank, and it was 92!His heater went wacko, obviously. I did about 1/2 or more water change instantly, with purifing drops and got that temp back down to about 75. He's still not right today. He just stays at the bottom or in his tunnel, he's leaning on stuff and of course not eating. This guy is in a 2 1/2 gal tank with a screen over him, and a light.
He is a survivor twice now as he has jumped out of his tank twice and lived through it! Two long falls too, before I got the screen. But now I don't know. He will move around when I move something in his tank. Come up to the top and go right back down and hide. Any suggestions?
