Class
Common name: Sea Cucumbers
Scientific name: Holothuroidea
Sea cucumbers, belonging to the class Holothuroidea, are echinoderms with elongated bodies and leathery skin. In reef aquariums, they play a crucial role in the cleanup crew, consuming detritus and aerating the sand bed. They are generally peaceful and can coexist with most tank inhabitants. Some species host symbiotic organisms, including pearlfish, which reside inside their bodies. It's important to choose a species that matches the tank's size and bioload, as some can grow quite large and may release toxins if stressed.
