Common name: Clionaid Sponges

Clionaidae, commonly known as clionaid or boring sponges, are a family of sponges that have a unique ability to bore into calcareous substrates, including coral and limestone. This process is facilitated by chemical dissolution and mechanical action. In reef aquariums, they can be both beneficial and problematic. Beneficially, they contribute to the natural bioerosion process, but they can also cause damage to live coral structures if not kept in check. They are not typically added intentionally to aquariums but may arrive as hitchhikers on live rock.
