I have had a veil tailed betta for about 3 months now and he has been doing great but lately my room has been getting cold so I got one of those heaters that maintains a certain temperature for it. Well I put it in and he seemed to be doing fine at first. Then after a while I noticed he had started hiding in the bowl which was unusual. I didn't think to much about it until he had gone two days without coming out. So I took the little hollowed out log bridge that he was hiding in out and at first I thought he was dead but then I saw he was still swimming with one fin although he was just laying on the bottom. I watched him for a little bit and he didn't have any trouble swimming but all of his fins were clamped really bad. He didn't show any signs of having a distended stomach or of being tipsy he just seemed depressed and would just lay on the bottom of the bowl which is unusual he usually is a very active little fish.
Any input would be appreciated!
