After more than a month of trying, I finally caught him with the camera!! He's still quite small, that's a fairly large snail in the picture. Any ID help would be much appreciated. He only comes out at night and HATES flahshlites :( I posted a thread a while back when I realized I had this cool little hitchiker. He came along with with some LR from Tampa Bay Saltwater. This little guy is eating hermit crabs like popcorn. One of my clown fish has suction cup marks on him. A few nights ago he tore one of my attached clams off the LR, crushed the shell and ate it!! The clam was about 3 times his size!!!! I would love to keep him but the damage he's doing now is amazing. I can't imagine what he'll be like when he gets bigger. The owner of my local fish store offered him a nice BIG home. I'm going to transfer him in a few days. I want to thank you all for your help. He's doing very well and seems to be quite healthy but I need a cleaning crew in my tank!!
