I've had a red dragon scale male veiltail for weeks now and he won't unclamp his fins! When I first brought him home he had some swim bladder trouble but after a few days of epsom salt baths it cleared quickly, other than that, hes had no more issues. A few days after his swim bladder issues cleared up he started clamping his fins. He has yet to stop and its been at least two weeks now. He has no visible issues. Hes eating, active, and is blowing bubble nests. I feed him new life spectrum betta pellets twice a day. Hes in a 2.5 gallon aquarium heated to 78 degrees. It is not filtered and he gets water changes twice weekly. I use stress coat as my water conditioner. I've tried a little aquarium salt and that didn't make a difference. Any ideas on what could be wrong?
