I just unwrapped the towel that I use to keep my betta in the 2.5g warm and I found him at the top and trying to get down but he can't and he keeps turning sideways while trying to straighten him self but can't and just know he made it to the middle of the tank and keeps trying to get down but he just flew back up. He is also bloated which makes me suspect constipaton which is pressing against his swim bladder or he is fat and his fat stomach is pressing against his swim bladder. I don't have any peas. Is there something I can do till I can get some?
