Ok I had to move this here because now it seems like he's having seizures. Here's what I posted in the Betta Care:
For the past week or so my Betta, Noche, has just been spazing out in his 14gal tank. He swims rapidly and then rapidly down to the bottom and back up. Then he'll just float, get some air, and do it again. I thought maybe it was the ammonia levels in the tank which are 0.0-0.25ppm (I have a really hard time telling the difference between the colors). There are zero Nitrites and zero Nitrates. I cycled this tank with shrimp and haven't had any problems till recently. I had to get rid of just about all the plants because they were dying and decaying. So he lost some hiding spots. The 14gal has treated water and it kept at 80*F. I just took him out and put him into a temporary 1gal bin that I used for him while I was cycling the tank.
I had the same problem with my other Betta too, just seems like he was just way over excited living next to another Betta (The 14gal was divided) so he is in his own 2.5gal that I change every other day.
Has anyone had any similar problems? He was fine in the tank till recently so I'm thinking something might be wrong with the tank. He's in a 76*F bin right now until I can figure out what's wrong and hope he calms down. His color is still there and none of his fins are clamped.
As for the seizures maybe he was having that before and it didn't seem like it in the big 14gal. He still stops to rest and then get some more air but I really don't know what I can do for him! I thought he would be happy to have his mug too. It was at the bottom of the 14gal and since it's a tall tank I thought that it was too much trouble for him to reach and then have to get air.
