hello, I posted about this before but haven't received any replies in several days. I have a clownfish with 3 other clownfish in a 30 gallon QT. this is week one. after day 2 or 3 this fish seperated from the group and began swimming vertically facing down near the surface in a corner (see video). then a few days later and he started swimming on his side near the surface (see second video). he can go down and hang out with the others if he gets startled or for feeding and he's been eating fine. could this be swim bladder disease?
