Family
Common name: Sea Urchins
Scientific name: Echinidae
Echinidae, commonly known as sea urchins, are a family of echinoderms characterized by their spiny globular bodies. They play a crucial role in marine ecosystems, often grazing on algae and helping to prevent algal overgrowth on reefs. In the aquarium, they can be beneficial for controlling algae, but their spines can be harmful to soft-bodied tank mates. They require stable water conditions and plenty of live rock for grazing. Some species may prey on corals, so careful selection and monitoring are essential for reef compatibility.
