P.S. i love your betta have you seen the pictures of mine? he is one of my favorites.he is trained to feed from my hand but my hands are usualy dirty so i dont do it often but i love him. he looks a bit like yours but smaller.
I also saw your post on the cory page and that you are considering getting some and there are many options but i would strongly recomend arcutus corydas or skunk corys.they are very playful and can be tought to come out in the day unlike some corys.
I must say they are very beautiful fish.not to be kept with other fish unless you get the other fish at the same time and size.i love mine though.he is 5 years old and still growing:D haha but very good fish to have.mine wasnt much more than 2 inches when i got him.
