That is so cool how you got your avi like that. Amazing what a little turning can do! Some female bettas? Neato! Are you going with the "wild type" with stripes or the colorful ones? The neat thing about them is that they can be community fish!
I think that is awesome! They make such cool interactive pets. Mine loves to follow the mouse around the computer monitor (his bowl is next to the computer). It's amazing how interactive they can be, a lot of people don't realize that.
