Common name: Rough scallop sponge

General information

Myxilla incrustans, commonly known as the Encrusting Sponge, is a species of sponge found in marine environments. This sponge is characterized by its ability to form thin, encrusting layers over rocks, shells, and other hard substrates. It is often observed in a variety of colors, including yellow, orange, and red hues, which can add a splash of color to the reef aquarium.

Care

Encrusting Sponges like Myxilla incrustans are relatively low-maintenance invertebrates in a reef aquarium. They require stable water conditions and benefit from moderate to strong water flow to deliver nutrients and remove waste. It is important to ensure that they are not smothered by sediment or algae, as this can inhibit their growth and health. They do not require additional feeding if the tank has a sufficient amount of dissolved organic matter.

Reproduction

Myxilla incrustans reproduces both sexually and asexually. In the aquarium, asexual reproduction through budding or fragmentation is common, allowing the sponge to spread across the substrate. Sexual reproduction involves the release of gametes into the water column, but this is less likely to occur in the controlled environment of an aquarium.

Habitat

In the wild, Myxilla incrustans is typically found in shallow waters, often in areas with strong currents which facilitate the sponge's filter-feeding habits. They are commonly found on rocky substrates, pier pilings, and other man-made structures in the ocean. In the aquarium, they should be placed in areas with similar conditions to their natural habitat to thrive.
