Betta fish with holes in fins?
I bought a halfmoon male betta fish (Fernando) about 2-3 weeks ago. He lives in a 10 gallon tank with 3 olive nerite snails, and some live plants. He has a heater (the tank is kept at about 80 degrees Fahrenheit) and a Fluval 106 filter (which, by the way, is never kept on at full power). He's seems happy - at least, he's quite active.
Yesterday, he blew a bubble nest. The bubbles were small, and there were many in a cluster at the side of the tank, but there were also random bubbles scattered across the top of the tank. I think that when sick bettas blow bubble nests, the bubbles are scattered around randomly but they are large. Fernando's bubbles were scattered around but they were small. Also, today, I noticed several tiny holes in his anal and caudal fin. However, they didn't seem to bother him - he seemed perfectly healthy.
Are the two things connected? Should I be worried? If this is a problem, are there any treatments?

EDIT: I put the picture I wanted to post on this as my profile picture, actually. x3 The red circles are where the holes are.
