Your better off getting a real rock. A huge seiryu stone could be cool
I find that some of the artificial pieces are done well enough to go in my tanks.I have two of the large driftwood stumps that I bought a few years ago....each one looks to be a bit bigger than the rock formation piece that is in question and they didn't cost nearly as much.Petsmart aquarium products are very poor for the price. Maybe it would have a ok value at 1/2 the price.
