LOL, get ready for this...
tank = about 12x48x18, so however big that is
water = fresh
fish = 1 medium picostimous (sp?)
3 black skirt tetras
3 zebra danios
funny story actually about the cheap arse fish. we inherited the tank from my GF's dad when he dicided he wanted to be a truck driver. when he gave us the tank he told us "just fill it up, let the water come to room temp and put the fish in". aparently he didn't realize that we were on city water and he was on well... needless to say the chlorine killed all the fish within 18 hours or so. the fish that we have now are the "tester" fish. we bought them to make sure we didn't kill any more expensive ones. we've had them for over a year now though...
Sounds like a 20 gal.
The things that folks do to fish

I had that problem with a Sister-in-law! I used to LOVE my fish tank...I used to go so far as to breed a few, but we were moving and my tank (150 gallon, about the size of your couch

) developed a leak soon after that. I didn't realize it, and one day while at work, something must have happened (got knocked or just too much pressure) and when I came home, I found my entire fish tank on the floor, all my fish dead, gravel everywhere. I haven't had the heart to start another tank since then, but I go to the fish store every other week to look at 'em, and I take care of several outdoor ponds that I've set up for people....you're making me get all misty, dammit!

From the size of your tank, check out some Gouramis. Blue's seem to be the hardiest, but dwarfs will be more in line with the size of your tank, and they're a bit more colorful!
Just don't throw any Cichlids in your tank or you'll soon have a Cichlid-only tank

Cool, though, and thanks for sharing!

Did that ringtone work for you?
