clown fish bloated??

Just fed my fish a few minutes ago and just noticed my one clown fish acting funny now. Looks like she is having a hard time keeping herself down in the water and wants to rise to the surface. Looking closer her belly looks quite full and bloated, more so than normal. Still comes to the front of the glass when I approach. I'm not going to try and catch her and stress everyone out, hopefully it resolves. Any ideas?

 

It will resolve.

Sometimes when they eat they also swallow air and this happens but it usually resolves in a couple of hour.
