Response to photo comment:
I was lucky enough to get a very tolerant betta that is compatible with just about any fish under the sun. I've wondered if he would be okay with even angel fish, but since I have guppies I decided against trying :)
Also, thank you. I try really hard to get good pictures of my fish, which often involves taking hundreds at a time and only getting one or two that are good. I hate photos that are done in artificial lighting or with the flash.
