Bettafish - Awesome! I don't have one right now, but they do have timers to turn the lights on and off at the same time every day. I've always been pretty anal retentive about checking my temps and I've never kept species that are very picky about fairly minor temp changes (especially since the overall temps in my house stay pretty stable). I pretty much have it down to a seasonal sciance, though. Once the weather starts to go cold for the season, it's time to switch out all the enclosures to larger heat bulbs - one reason I have three light shrouds on the boa enclosure is because if I do it right, I can just unplug one of the heat emitters durring the warm seasons and the temps will be perfect. That and the snakes are pretty good at telling me if they're not comfortable - if they stop eating (and they aren't going into shed or have another reason not to eat) one of the first things I try is up the heat a bit, or if they spend most of the time on one side of the enclosure, it's time to adjust the temps. But with me at college most of the time now, and I obviously can't take all the kids with me to my dorm (though it'd be fun to freak out the boy's floor below me :D ), I've been strongly considering a thermostat both for my peace of mind and so my parents/little sister don't have to check on the temps as much.
Bettalover - Awww... Hoggies are just adorable in anything they do, in my humble oppinion :P
