Genus
Common name: Aaptos
Scientific name: Aaptos
Aaptos is a genus of sponges in the family Suberitidae, known for their hardy nature and ability to filter large amounts of water. They are characterized by their conical or massive shape and rough, leathery surface. Aaptos sponges are not common in the reef aquarium trade, but when kept, they require moderate to strong water flow and good water quality to thrive. They are non-photosynthetic and feed on bacteria and tiny particles in the water, making them useful for nutrient control in a reef tank. However, they should be carefully introduced to established systems as they can release toxins when stressed.
