Common name: Red Tree Sponge

General information

The Red Tree Sponge, scientifically known as Clathria cervicornis, is a species of marine sponge found in reef environments. This sponge is notable for its branching, tree-like structure and vibrant red coloration, which can add a splash of natural beauty to any reef aquarium. It is part of the Demospongiae class, which is the largest class within the phylum Porifera, encompassing over 90% of all sponge species.

Care

Clathria cervicornis requires a well-established aquarium with stable water conditions. It is a filter feeder, relying on water flow to bring it nutrients. Therefore, moderate to strong water flow is essential for its health. It does not possess photosynthetic symbionts, so lighting is not as critical as it is for some other invertebrates, but it should not be kept in total darkness either.

Reproduction

Reproduction in Clathria cervicornis can occur both sexually and asexually. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other individuals. Asexual reproduction can occur through budding or fragmentation, allowing the sponge to spread and colonize new areas of the reef.

Habitat

This species is typically found in the Caribbean Sea and adjacent regions. It thrives on reef slopes and overhangs where it can take advantage of the water currents for feeding. Hobbyists should aim to replicate these conditions to some extent to ensure the health and growth of the sponge in captivity.
