Pudge has had this weird bulge on his sides since I got him and I figured it was because of being thin. And well it did seem to help. But not enough to make it go away. I decided to ignore it (BAD betta mama move :(
After randomly looking at the anatomy of a betta, I realized it was his swim bladder. And now I'm worried although he exhibits absolutely no difficulty swimming or flaoting.
I've only had him for about 2 weeks and he's been like that since I got him. Is there any problem with a pronounced swim bladder?
