new creature in my tank (uninvited)
So i went into my tv room last night and flicked the lights on (not tank lights) and noticed a quick movement on top of one of my rocks. What i believe was some sort of crab ran when there was any light at all in the tank so i could just barely see him in the crevas of a rock. I'm worried that this may be one of the crabs that are not good to be in a reef tank. Right now at blue world aquaria they have one of these crabs as a pet at the front desk and from what i remember it was a heavily amoured little critter that was white in color. What i saw in my tank didn't seem to be as bulky and had what i think was some black spotting........What do you think it could be and what kind of damage could it cause (worst case scenario). I really don't want to take my tank apart looking for him so i was thinking that if there were certain things a "bad" crab would do to my corals or fish i would monitor that and then take the appropriate action if he is in fact a threat to my reef....

Small glass or jar with some bait in it against a rock overnight.
Most crabs are bad.  Better take it out if you can.

Small piece of shrimp or fish and put a rubber band tied to a small rock so it does not float away. Put it in at night when your fish are sleeping.

Be prepared for frustration the likes of which you've never seen! I tried traps and one night got so fed up I sat there with a big knife in the water just above his rock for what must have been more than an hour. Left a piece of shrimp just under the knife. Stabbing a glass tank with a knife. SMART.
I'm sure my hand stunk more than the shrimp. I never caught the devil but I had a nice surprise one day when he just died on his own. This is of little help to you but good luck!
