I checked out your porch aquariums. Wow! That is some serious fish-keeping. My wife is already concerned about my new fish obsession; I can't let her see that photo. It gives me some ideas of what I could with our porch though.
I'm starting to get serious about a new 55 gallon. Craigslist has one locally that I may check tomorrow if it is still available.
I'm head to my LFS this evening to get some betta flakes. My betta won't eat the betta pellets; he just spits them out. I've been feeding him regular tropical flakes, but I've read that isn't the best diet.
Once more, thanks to everyone for the all the sound advice.
