Ok about 18 years ago I purchased what I believe was called cat paw coral (dead). This was used for decorative pieces in my first FOWLR setup. They've been dry 4 years 6 months ago I placed them in a friends saltwater setup. three days ago I transfered my 54 corners' contents to a 5' 120 gallon when if ever can I consider these pieces to be live rock? I added these pieces to the 120.
