I have some hitch hikers and need some help!

[TempestGod]

First off, thanks for taking the time to read this. I got some hitch hikers one a piece of live rock I picked up about a week ago. There are a few that I can positively ID. There is at least 1 Feather Duster, and I have also seen a small pink colored bristle worm. There are also a few creatures i can ID because the spend all their time hiding in holes of the live rock. Is there any way I can lure them out without hurting the other things living on the rock? I know for sure one of them is a crab about the size of a quarter. The other one i cant even tell what it is, all i can see are a few legs and they retreat back into the rock if i shine a light in there. They kind of look like boxer crab legs but i cant tell for sure.

Have you tried a flashlight with a red light? They do not mind that as much as the white.

You could put a bottle trap with a little meaty food in it to catch them.

If you have blue lights on your tank that would be a great time to see the critters. A lot of what we have in our tanks are nocturnal and they come out when the main/white lights turn off.
