    Hi all today I bought a piece of live rock and noticed worm like creatures in it. Nasty

    I dipped the rock in revive and more came it and I fished one out of the tank

    Are these bristle worms and are they bad? They look nasty lol[​IMG]

    bristle worms, generally beneficial detritivores (eat fish poop, uneaten food and dead things) dont touch em they have glass shard like spines all around them.

    Watch out about touching them... painful buggers because their tiny spines can stick in your finger. However easy enough cure is to soak your finger in vinegar since they are IIRC calcium carbonate based.

    They can be good or bad. Depends on how many there are Mainly in my opinion. Only a few, no big deal. I have seen plague proportions tho.

    They are always bad IMO. They can harm or irritate you and your corals and if they are multiplying or growing large in your aquarium are a sign that you are over feeding, under vacuuming your sand bed, or lacking other detritus eaters such as pods, cucumbers, or filter feeders.
