Help ID my fish

I'm going to try to find a 20 gallon, and maybe turn this 10 gallon tank into a planted beta. What would go well with a male beta?

Also, I'm relieved about the plants, but I did have lots of tiny bubbles all up under the broad leaves of whatever this plant is, and also all over the underside of the anacharis. I do have a bubble wand or tube on the back wall of the tank, could that be where the bubbles came from? I don't have an airstone though.

I'm going to try to upload some pics of my tank, on a new thread. I hope someone will tell me what the plant is that I've got.
