Common name: Leaf sponge

General information

The Elephant Ear Sponge, Carteriospongia foliascens, is a large and visually striking species of sponge found in the warm waters of the Indo-Pacific. It is known for its broad, ear-like flaps and vibrant colors, which can range from purple to brown or green. This sponge is not only a beautiful addition to the reef aquarium but also plays a crucial role in the ecosystem by filtering water and providing habitat for a variety of marine organisms.

Care

Carteriospongia foliascens requires a specific set of conditions to thrive in captivity. It needs a moderate to strong water flow to deliver nutrients and remove waste, as well as good water quality with low nitrate levels. Lighting is not a significant factor for sponges as they are non-photosynthetic, but they do require a steady supply of dissolved organic matter to feed on. It's important to note that sponges should never be exposed to air, as trapped air bubbles can be fatal.

Symbiosis

While not hosting a wide range of symbiotic relationships like some corals or anemones, sponges like Carteriospongia foliascens do provide microhabitats for small invertebrates and can be part of a larger symbiotic community within the reef ecosystem. They are often found living in close association with other invertebrates and algae, contributing to the biodiversity of the reef.

Habitat

Carteriospongia foliascens is typically found in reef environments, often on reef slopes or in lagoons where the water movement is sufficient to bring food particles to the sponge. They can be found at various depths, usually ranging from the shallows down to about 30 meters.
