It's been nearly a decade since I was active. The last house I rented, if I'd had the 100 in the living room and filled it with water, it would have landed in the basement. (the 100 gallon tank, plus accessories, weighed well over 1000 lbs.)
I've recently reloacated to hell, er.., L.A., and am looking for a place to buy. Once that's done, i'll definetly set several tanks up again. Probably another south-american community (100g), and a couple african breeder tanks (50's, 30's).
