Common name: Fimbriated Sponge

Scientific name: Myxilla fimbriata (Bowerbank, 1866)

General information

The Fimbriated Sponge, Myxilla fimbriata, is a marine sponge species that adds a unique texture and color to the reef aquarium. This sponge is characterized by its branching structure and fimbriated (fringed) edges, which give it a delicate, lace-like appearance. Sponges like Myxilla fimbriata are filter feeders, playing a crucial role in the nutrient cycle of reef ecosystems by processing dissolved organic matter.

Care

Myxilla fimbriata requires a well-established aquarium with stable water conditions. It thrives in areas with moderate to strong water flow, which facilitates its filter-feeding habits. Lighting should be moderate, as excessive light can promote the growth of algae on the sponge's surface. It's important to maintain high water quality, with low levels of nitrates and phosphates, to support the health of this sponge.

Reproduction

Reproduction in sponges like Myxilla fimbriata can occur both sexually and asexually. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges. Asexually, sponges can reproduce through budding or fragmentation, where a piece of the sponge breaks off and grows into a new individual.

Habitat

Myxilla fimbriata is found in a variety of marine environments, from shallow waters to deeper reef zones. It often grows on rocks, coral rubble, or other hard substrates where it can anchor itself securely. In the aquarium, it should be placed in an area that mimics its natural habitat, with plenty of water movement and access to suspended particulate matter for feeding.
