My gourami has "air bubbles?" on one of her gill? What is it? Is it harmful? contagious? Help!

I tried to get some images with my camera, but they are not the best. It basically looks like air bubbles inside his gill. Is that normal? How do I deal with it?

This is from the day I bought her, as observative as I try to be, I missed something very noticable... It's her 2nd day here in 25g. My LSF is awful so I don't think I'll be getting a replecment even if I bring her alive. She eats and is energetic.

Also, a side question: What type of a gourami it is?

 

I'm not sure about the bubbles, but I think she's a red/ flame dwarf gourami.

 

Although the pictures are bad, this is not a dwarf gourami, but a golden/orange colour morph of the three spot gourami.

Bubbles don't have to be necessarily bad in labyrinth fish, but without a good picture nobody can tell for sure.

 

MacZ cool, I didn't know they came in that colour!

Just research a bit. Right from the top of my head I can think of at least 5 different colour morphs of that species, but couldn't name them all. I'm not a gourami keeper, I just have a thing for fish ID-ing.

I got some more pictures, and even fished her out for a couple of pictures images
