In the above link, I have uploaded a movie of the crab which I have noticed lurks in one of my live-rocks. Last saturday I added 2 small goby's to the tank, a yellow one and a green one. The green one I never saw since adding it (might be hiding in live rock?) the yellow one however was visible every day until today. Could it be this crab has eaten it? The only time I noticed the crab was after I feeded the fish I noticed something moving in the hole of my liverock, since then I've been paying extra attention to it, and every time I feed the tank it moves partly out of it's hole for what I can only imagine is hunting for food.
Any suggestions on what to do? I can't easily catch the crab as it's always inside the liverock, also the liverock it's in is at the very foundation of my reef. Any advice would be greatly appreciated.
