I am new to reef tanks. How do I remove them without impaling myself?

I have read that some of them can/will munch on soft corals like zoos.
Also, the algae that they eat is coralline.
Personally, I dont think they add anything beneficial to the tank and I
just
took the three that I had to the LFS for store credit a month ago.

I bought live rock for my new tank about 1.5 months ago. (Carribean
Aquacultured) I noticed a couple of urchins came with the live rocks,
but
now I have seven. Are these creatures a pest I need to worry about? I
read
they eat algae which is fine by me, but do they do any damage to other
reef
creatures?
