I don't know what to do. Ever since we moved into our new place, a circular white discoloration appeared where his back fin is attached to its body, and got bigger and bigger over the last 6 months. I went to petsmart, and they suggested it was ick, gave me a some medicine, but it didn't help. Seems to me that icks form all over a betta's body, but this was only one spot. Now it got bigger and turned into a bump, and the bump kept getting bigger, and appeared on the other side of the fin. Now my betta is swimming around, with no appearent change in his behavior, but a huge white bump.
i have no idea about what to make of this.... please help.
