is this swim bladder
So I got a new betta fish today which I bought online. He is swimming around a little bit, but for the most part he either lies on the bottom of the tank or he is at the surface. When he is at the top he is basically lying vertical with his head pointed to the surface
Is this swim bladder or is he just shocked from the journey. I don't want him to die since he cost me £30 and I've been waiting a week to get him.
At the moment he's just sitting in the corner at the top of the tank hardly moving.
