are you referring to the lr you already have in the tank? cuz it will be fine witht the key west rock too. i would keep an eye on the rocks to make sure no asptia(bad anemones) or manjos and what not don't start growing.
well the rock has been out of water since the 1st of november my wifes parents got it in key west so i would think whatever is on it or in it should be dead right?
i put two of the dead rocks in my tank and they seem to be doin fine i checked it this morning when i got up and theres nothin growing so i think i'm good.
