Hello TRT!!! I purchased a tiger sand conch about 3 days ago. I only saw him for the first day and that was when I put it in the tank. It burrowed down in my live sand but I could still see the top of its shell. The next morning it had completed buried itself in the sandbed and I haven't see it since. I hear they will poke their eyes out of the sand but I haven't seen any signs from the conch. Should I be concerned? Should I try to find him and place it back on top of the sand?
