I'll remember this for when the time comes to remove. Thanks.albie611 said:when they get big(over 6-8 inches) remove with a bristle worm trap.
take a regular 16oz. soda bottle cut off the top 1/3 and invert it into the bottom (making a funnel), punch a hole on both sides and tie together to secure. (i use zip ties) , bait with a piece of shrimp and place in tank , check often and remove when the worm is inside the trap.
using this method has worked well for me and you get no bristle "splinters".
happy reefing.........AL
