Order
Common name: Bristle Worms
Scientific name: Eunicida
Eunicida is an order of polychaete worms known for their bristly appearance. These worms are often found in reef aquariums, either introduced inadvertently or as part of the clean-up crew. They play a vital role in the ecosystem by breaking down detritus and aerating the substrate. Some species, however, can grow quite large and may become a nuisance by preying on small invertebrates or corals. It's important for hobbyists to monitor their population and remove larger individuals if necessary.
