Hi, I don't know if this is actually an emergency, but one of my spotted corys has begun to have this problem. I think it may be it's swim bladder but I don't really know. At first it started falling over, now it's swimming upside down. I called a local pet store and asked them, and they think it's the swim bladder. They said if it is this, there's nothing to be done. Does anyone have any ideas?
