yea, I bought that rock waterfall peice of crap for a x-mas present and It got regifted so I just tore it apart used the flat rocks for the hide and some of the round river rocks for weighting down the plastic plants.
i have a fish room all planned out for my future home. ive even made a drawing of it. it includes 5 tanks. 4 of them are 180g and one is a 120g saltwater. although i may have to alter the picture for added tanks.
