My live rock was taken directly out of the sea about 2 mins from my house and i collected all the live rock in a bucket in 10 mins and put it into my tank with alot of hitch hikers such as brittle stars, mantis shrimps, mysterious transparent shrimps and some fuzzy looking crabs but #1 and #2 creatures are difficult to take a pics of so i drew them #1 is a white worm that hangs off the live rock and digs into the sand but it only comes out at night. #2 is some kind of creature that extends its tentacles out of the live rock and dragging it across the sand picking up grains of sand, their tentacles are the size of a needle and transparent are always out, but they really help to clean up the sand.

The one could be a peanut worm: harmless: looks like a peanut with an elephant trunk and never leaves its rock. The second could be what I personally call 'fisher-worms': they constantly cast and draw in their tentacles. Spionid worms, I think they are. Harmless, but can become a pest if too numerous.

Mantis shrimps will kill fish and other crustaceans: a dedicated tank for them. Fuzzy crabs should go into the sump as you find them: good cleaners, but prone to eat corals and also their neighbors.
 
thanks so much , i always wondered why the fuzzy crab was always eating close to my coral he is like the energizer bunny keeps on going....., but those mantis shrimp are annoying with knocking noise but i'll soon find a solution.
