It is. Most rock on a beach is going to be covered with water at some point, there by making it live rock and illegal to harvest. My cousin works for FWC, so I asked him plenty about this subject lol. I always wanted to bring stuff like that home when I was younger, but as i got older, I realized it was just better in the long run to leave it where it was. Noah, I thought I saw in another threads that other people told you not to get rock from beaches like that? Tank’s coming along nicely though!
