Wrassecal, thought I might add, I went to Norman today and checked out Crystal Clear on Flood. Best live rock I have seen in a LONG time in OKC area. Bought 4 pounds of it in fact. And rather cheap too, for this area at least. I also saw the largest hermit crab I have seen in my life. Thing was the size of a football! I am going to ordera box of rock through this place when I get the money. Their rock is absolutely beautiful. Thanks for pointing me in the right direction. Anyone in the OKC area that hasn't been to Crystal Clear Aquatics in Norman on N. Flood should try to get out there and have a look see. Its a small shop, but WELL worth it.
