Betta breathing like a goldfish

I just brought him home from WM. The poor thing wasn't moving.
When we got him into his tank he perked up. Then he started to breath
like a glodfish would. He is opening and closing his mouth like one. My other two don't do that. Why is he doing this and can I do anything to get him to stop. Thanks, Lilac

Is he going to the surface for air at all? Does he seem to be in distress? Some Bettas seem to yawn, where they open and close their mouths repeatedly, but they aren't breathing that way, as it is usually done under water. Are his gills working? Are they red or inflamed at all?

His gills look fine. He doesn't look like his in distress. I haven't seen him go to the top in a long while. I hope the picture came through.

He does look all right to me. The gills look normal, but they are somewhat oddly colored. I'm chalking that up to his normal coloration, though.

How's his behavior over all? It is quite normal for Bettas who have just come home to show a suppressed attitude, and appear pale and weak. They have trouble adjusting sometimes. They often do not eat, no matter how healthy they may be. Is he eating? Does he swim all right?

You should notice him heading up to the top for air sooner or later. They can go quite a while without doing so, but they prefer not to. If his gills are working smoothly (you can see them moving in a smooth fashion, and he does not appear to be struggling to breathe), and he makes a venture up to the surface for air and seems to gulp at the surface, then he's probably fine. But keep an eye on him and make sure he does this.

Thanks Kiarra, He hasn't gone to the top in an hour, probably more than that. He hasn't eaten anything.
I do know it's not strange for him not to eat. He doesn't seem to be struggling, thankfully.

Can i just say hes a cool looking betta!
