What is wrong with my betta?

[CatAndFishFan]

Well...I've had some trouble with my little betta fish, Phinneaus lately. He lives in a 3 gallon bowl with some live and a fake plant, a rock and...well, that's about it. I'm not sure what he has, but he's definately not well. His symptoms are:
a white spot on the bottom of his top fin
his bronze belly (Phinneaus is a purple-redish betta)
a belly that I THINK is a tad swollen
If anybody could help me, I'd love it. Thanks!

Whats his water temp.?
If its to cold, there ya go, problem pretty much solved.

Stress also causes these things, and Betta get stressed when they dont have a really good hiding spot. Put like a little hollow tube like thing in there.
