I was going to buy a peice of this rock but every one wants around a dollar a pound, not includeing shipping! I want it for my 125g cichlid tank, and there should be a cheaper way to get the same result! Right now I have alot of caves/plants for them to hid out and make territorys, but with this set-up the fish don't feel comfortable enough to swim in the middle of the tank and spend alot of time on the bottom. I was thinking of PCV pipe but really don't know how to start ? Anyone with idea's or good links, I'd love a response. thanks
