Common name: Sponge Coral

General information

Cymbastela coralliophila, commonly known as Sponge Coral, is a species of marine sponge found in coral reef ecosystems. Despite its common name, it is not a true coral but a sponge that exhibits a close association with coral environments. This species is known for its unique growth form and the role it plays in the reef's ecology.

Care

Sponge Coral requires specific conditions to thrive in a reef aquarium. They need moderate to strong water flow to facilitate feeding and gas exchange, as well as a stable environment with high water quality. It's important to maintain low levels of nitrates and phosphates, as sponges are sensitive to poor water conditions. They are filter feeders and benefit from supplemental feeding with planktonic foods.

Symbiosis

Cymbastela coralliophila has a fascinating symbiotic relationship with microorganisms, including bacteria and single-celled algae. These symbionts can provide the sponge with nutrients through photosynthesis and other metabolic processes. This relationship is a key aspect of the sponge's survival and efficiency in nutrient-poor reef waters.

Habitat

This species is typically found in the Indo-Pacific region, inhabiting coral reefs and adjacent habitats. They are often seen growing on or near live corals, which is reflected in their common name. The depth range for Sponge Coral is usually within the photic zone where light penetration is sufficient for their symbionts to perform photosynthesis.
