Over the course of time I have had my tank running I've noticed 4 hitch-hiker crabs in my tank. Two don't bother me much, two I really want gone.
Today I was delivered a stroke of luck when I removed a piece of live rock from the tank and moved it to one that I will be bringing me up shortly. My least favorite crab is it in it! I tried to flush him out with a flush of fresh water, but he has too many paths dug out in the rock. I've heard about trapping him in a shot glass with a piece of shrimp but I have none at the moment...has anyone else found something enticing enough to work?
Now here is my second, completely messed up question. I found one of my hitchhiker's big claws lying on the sandbed today. Not an exoskeleton, but the whole claw! I've heard clicking coming from the tank, but I've had this rock for 5-6 months and haven't noticed any hermits or snails missing or smashed up. Maybe the crabs fought or maybe..eeee...i don't even want to entertain the idea that...
