I have a female CT in a 29 gal community who is acting strange. I noticed today she is sitting in the same spot at the top for hours. Her beautiful purple color has faded. Her fins are clamped. Her stomach doesn't look too alarming but it is bloated as if she's ate a bit too much and I haven't even fed yet today. I've never had to treat a betta for anything but fin issues. Anyone know what's up with her?
