Really pretty colors on your betta, and nice aquarium! I'm sure he loves his new home. If the fuzzy white stuff on him looks like cotton, it's most likely a fungus infection. I got a new betta with an infection, but theyre pretty easy to treat. I use Liquid Fungus Cure By API (Aquarium pharmaceuticals, I think.) Also the Jungle Fungus Eliminator apparently works well, though I've never used it. Or you can put in 1 teaspoon of aquarium salt per 2 1/2 gallons of water and one drop of Aquarisol per gallon. That works pretty well too...
