But it could also be harmless.

TheAmphinomidae- Amphinoids are also known as "fireworms" and have calcareous setae filled with poisonous secretions. When irritated, they erect their sharp setae which break off at a touch releasing their poisonous contents into the wound. Most species are found on corals, rocks and other hard substrata covered with attached organisms. They swim well and can be brilliantly colored. All but one species can be considered harmless and are great scavengers.



Species shown below : Hermodice carunculata - This is the one species of fireworm that you do not want in your aquarium as it is a known predator of corals.


The below pictured specimen is a Pherecardia striata, also a member of the fireworms and is a scavenger.

Genus Pareurythoe , which has very small caruncles.

Eurythoe complanata - Probably the most commonly found worm and is a harmless scavenger, a benefit to our systems.

Those are some ugly worms... yuck
