strange critter id

[cgh38]

I don't have a pic. of it. he barely comes out (half way) of the same hole everytime I feed the tank he's yellow greenish body with a small hook or claw looking thing at the tip of the head and it has 2 antennas like the pistol shrimp, any sudden move or fish swimming by it he quickly hides back into the hole.
maybe someone can reccomend a website that has pictures of marine critters so I can Id this guy?
Thanks in advance

Do a search on mantis shrimp. It sounds like that might be what you have. If you even think it is. Pull the rock out when you know he's in there and figure out how to deal with it. Last months RC home page had a great article on mantis.

Thanks bax,
I do have a mantis that came with the rocks but this one does not look like a mantis I'll look it up but I dont think that mantis have antennas like the pistol or peppermints

Ok, I was able to take a pic of the critter now I can see the eyes and what it looks like a claw that are in front of his head but he only has one claw
