Common name: Reinwardt's Sponge

Scientific name: Clathria reinwardti Vosmaer, 1880

General information

Reinwardt's Sponge, scientifically known as Clathria reinwardti, is a marine sponge species that adds a vibrant touch to any reef aquarium. This sponge is characterized by its bright red to orange coloration and volcano-like shape, which can provide a striking contrast against the various greens and blues typically found in a reef environment. Sponges like Clathria reinwardti are filter feeders, playing a crucial role in the ecosystem by cleaning the water as they feed on bacteria and particulate organic matter.

Care

Caring for Clathria reinwardti requires stable water conditions and moderate to strong water flow to mimic their natural habitat, where they are constantly exposed to currents that bring them food. They are non-photosynthetic and rely on the availability of dissolved organic matter in the water. It's important to maintain good water quality and provide supplemental feeding with planktonic foods to keep them healthy.

Reproduction

Reinwardt's Sponge reproduces both sexually and asexually. Sexual reproduction involves the release of gametes into the water column, while asexual reproduction occurs through budding or fragmentation. In the aquarium, fragments that break off can sometimes settle and grow into new sponges if conditions are favorable.

Habitat

Clathria reinwardti is found in the Indo-Pacific region, typically on reef slopes and overhangs where they can take advantage of the water flow. They are often seen at varying depths, which can range from shallow waters to deeper reef zones.
