This may sound dumb, but the other day I was putting a few new pieces of live rock in my tank. The rock had a LOT of veggie growth on it and some of it was coming off as I placed the rock. For a split second I thought I saw something dark green (about an inch long and not even 1/2" wide) on the bottom of the tank that then moved kinda quickly towards the lower inlets of the overflow in the back of the tank.. I just chalked it up to it being a piece of vegeation, but now am being paranoid that it may have been a mantis, even though I saw no legs, eyes, etc. It just seemd to move a bit odd. To put my mind at ease, my question is... Would a
mantis shrimp even come out of it's rock so easily in a bright tank?
thanks for your help.
