So heres the deal a fellow reefer is quitting the hobby and has given me everything from his old tank apart from fish and coral, so Im just debating wether I wanna change the right hand side of the aquascape it has some nice hidden caves for fish but not nice to look at. Also I have a couple of the same rocks used as spare. Heres a picture of the rock in the tank when he had to put it in 6 months ago.
