Common name: Red Encrusting Sponge

General information

The Red Encrusting Sponge, Mycale rotalis, is a marine sponge species known for its vibrant red coloration and encrusting growth form. It is a member of the family Mycalidae, which includes sponges that are often found in a variety of reef environments. These sponges are filter feeders, drawing in water to extract nutrients and oxygen.

Care

Mycale rotalis requires a well-established aquarium with stable water conditions and moderate to strong water flow to mimic its natural habitat. It is important to maintain high water quality, as sponges are sensitive to elevated levels of nitrates and phosphates. They do not possess photosynthetic symbionts, so lighting is not critical for their survival, but some ambient light can be beneficial.

Reproduction

Reproduction in Mycale rotalis can occur both sexually and asexually. Sexual reproduction involves the release of gametes into the water column, while asexual reproduction can occur through budding or fragmentation. In the aquarium, fragments that break off can sometimes establish themselves as new individuals if conditions are favorable.

Habitat

Mycale rotalis is typically found in tropical and subtropical reef environments, often growing on rocks or coral rubble. It can be found at various depths, usually within the photic zone where light penetration supports the reef ecosystem.
