I was looking at my tank tonight and my wife noticed an orange crab. Sorry no photo. Has anyone seen these and are they bad? I didnt like having it in my tank so I tried to catch/kill it, but it got away because my rock is sooo freak'n porous. It was very small about the size of a dime or a little smaller.

No way of knowing without a pic. If you really want it out you could watch and see what rock he is in and take it out. Try doing a fw dip but it could take a while for the guy to decide come out, or flush him out with a water hose. Not all crabs are bad tho. Keep an eye on him for sure.
