Something your going to seriously regret and they're not worms. Digitate hydroids are near impossible to get rid of once introduced. They can live off almost any level of nutrient.

From my understanding, Digitate hydroids have the strongest sting of about anything in your tank. Be very careful NOT to get in there with a bare hand! They also are known to spread very quickly... totally taking over your tank. That is what makes them so undesireable!
If you are just now noticing them, it would be the best time to try and clear them up. Kalk-paste should help... may take a couple applications. Ensure powerheads/return pumps are off for a while when you apply, so it isn't just blown away.

prbhasson & LakeEd are correct, they're definately one of the "scourges" you want to avoid. Unlike colonial type hypdroids that will often stay clustered, these haphazardly start appearing about the tank. Their sting is very strong and will limit coral growth significantly. They can/will also embed themselves in coral skelatal stocks, Euphylliids, Faviids and the like.
If it's only the one rock I would remove it and let it dry out for a few weeks. While kalk paste might work, it will only get the ones you can see at that time. Where there's one, there will be more so your success would be very limited. Because they can quickly retract into the sustrate(s) they occupy, it makes them rather difficult to remove or kill conventionally.
burning2nd, they will be most active after lights out. Check a few hours after the tanks been dark and see if it's any more abundant.
