Common name: Stone Sponges

The Petrosiidae family, commonly known as Stone Sponges, encompasses a group of marine sponges characterized by their dense and stony texture. These sponges are found in various marine environments, from shallow reefs to deep waters. They are notable for their robust skeletal structure, which is composed of a network of spongin fibers and often reinforced with silica. Stone Sponges can be an interesting addition to a reef aquarium, providing a natural and unique aesthetic. They are filter feeders, helping to maintain water quality by consuming bacteria and particulate matter. However, they require stable water conditions and moderate to strong water flow to thrive.
