YAY! So I went to Aardvark Pets today and talked to the man who ran it about what to feed him. He gave me a package of Hikari Betta Bio-Gold and said to feed 1-2, and if he eats those maybe a 3rd. He also gave me a little pamphlet on caring for a Betta for free.

I'm so darn happy - I came home, cleaned out the flakes and gave him 2 Hikari pellets - and he ate it all (so I gave him one more)!

Thanks for the suggestions you guys!!
