Heee! I got a new thingy today! For a while now, I've toyed with the idea of getting a fish tank. I kinda sorta wanted a 10 gallon, but I'm not really sure where I'd put it. I didn't want just a goldfish bowl, I don't really think a small bowl is fair to the fish. I wound up getting a 2 gallon tank, which will have a single male betta fish that I'll get next week. I'd like to toss in some neon tetras too, but I don't think they'd be happy in an unheated tank, plus it's probably…
