Potters Angel swimming funny?

[Bret61081]

About a month or so ago, my Potters Angel that Ive had for over 3 years started swimming strange. It still is eating like a pig, picking at the rocks and even still chases my Multicolored angel around. When I ran a LFS I had a customer have the same thing happen to hers untill she gave it to a friend. Sorry for the low quality video, I took it with my digital camera. Any ideas what caused this?

Looks like a swim bladder issue. From the vid it looks like if he is not swimming up he will sink to the bottom.

That was my first guess but why after 3 years would it just start? It is usually from collection but what is captivity would case swim bladder issues?

I would QT right away and try treatments of antibiotics. What foods have you been feeding yours?

I hope she makes it!!! They are my favorite angel!
