Pretty surprising to say the least, don't know how the little guy survived with virtually no water. I was ticked because the rock was almost bone dry when I received it due to a FedEx screw up. Wasn't planning on getting one, but I just can't get rid of him now. Was planning on having a single pair of one of the oddball clowns that are now bred, but do you think it's a problem with this guy already established? It's a Red Sea Max 250. Not sure if the display is 65 gallons, or if that includes the back of the tank with the pumps/skimmer/etc..
