Genus
Common name: Bristle Worm
Scientific name: Hermodice
Hermodice is a genus of polychaete worms known for their vibrant colors and bristle-like setae, which can cause irritation if handled. They are often found in reef environments and can play a role in the ecosystem by scavenging on dead organisms and detritus. However, in a reef aquarium, they can become a nuisance by preying on soft corals, small invertebrates, and even attacking clams. Hobbyists should monitor their population and remove them if they become too abundant or start to harm other inhabitants.
