I’ve just recently set up a quarantine tank with a couple of lumps of live rock, and today I noticed a clicking sound coming from the tank. Immediately I thought mantis shrimp because I know the sound well (I own a peacock mantis) and the clicking might well be a mantis or a pistol shrimp, but when I observed the tank for a few minutes after dark this little crab popped out of the rock. He’s about half an inch across, if that. When he emerged the clicking stopped- but surely something that small couldn’t make an audible clicking noise? It’s nowhere near as loud as my fully grown peacock whacking the her burrow (or the glass ) but it sounds like tapping a plastic pen against the glass.
Is this a baby gorilla crab? If not, what is it? And either way, could it be the source of the clicking or have I got another critter in that rock somewhere? And if it is a gorilla crab, should I try to remove it? I thought it was pretty cool finding a crab on my rock but word on the street is gorilla crabs are bad news.
