i noticed this good sized hitchhiker crab out in the open about a month ago and haven't seen it since. I see that it now has a lil cave in the sand under a rock towards the front. It look kinda brown and fuzzy with some black on half of its claw. It seems like a pretty big crab and its claws are good sized. I have noticed 2 of my pipefish all of a sudden disappearing and i thought maybe something like a crab was eating them. Well i looked in the cave and saw him eating part of my pipefish sad.gif i dont know if he scavenged it or killed it. I haven't noticed any of my snails missing but he's probably been nourished with my 2 pipes :/
I hope he's not a rock crab or some kind of predatory crab. what do you guys think? could i trap him?
