My wife and I bought a 28 G bowfront "for the kids" for Christmas, and we have both since totally gotten into the aquarium hobby. Years ago I had a tank that just had a couple angels, a pleco, and a big old nasty goldfish. I never did anything with it, really, other than drain it down to move back and forth from college. Never had any trouble at all, just got lucky, I guess. But this tank I have been monitoring everything, and that's half the fun for me.
We're in the process of getting a 90 G to be a FW and convbert the 28 to SW. Can't wait!! :D
