I used to have a betta -- it was a long time ago, but I remember I used to feed it special betta food (they have different dietary needs than most fish) and freeze dried bloodworms (he LOVED those). Bettas are prone to fin-rott (I don't know the technical term, but it's a little white poof -- kinda like fungus-- that eats away at the fins)
Other than that I don't remember much about bettas, only that you can't put two males in a tank -- unless you want Raja to have some delicious betta snacks!!
