Common name: Columella Sponge

General information

The Columella Sponge, Hemimycale columella, is a marine sponge species known for its vibrant red to pink coloration and encrusting growth form. It is a member of the family Hymedesmiidae and is often found in reef environments, adding a splash of color to the underwater landscape. This sponge is not only visually appealing but also plays a role in the reef ecosystem by filtering water and providing habitat for microorganisms.

Care

In the aquarium, Hemimycale columella requires moderate care. It thrives in well-established systems with stable water conditions. Good water flow and quality are essential to mimic its natural habitat and to ensure the sponge receives adequate dissolved nutrients. It is important to note that sponges should never be exposed to air, as trapped air bubbles can be fatal.

Reproduction

Sponges like Hemimycale columella reproduce both sexually and asexually. In the aquarium, they often propagate through budding or fragmentation, which can be encouraged by hobbyists for propagation purposes.

Symbiosis

While not hosting larger organisms like fish or shrimp, sponges such as Hemimycale columella have a symbiotic relationship with various microorganisms, including bacteria. These microorganisms can contribute to the sponge's nutrition and help with waste processing.

Habitat

In the wild, Hemimycale columella is typically found in the Caribbean Sea and adjacent waters, growing on rocks, coral rubble, or overgrowing other sessile organisms. It is often seen at depths where light is sufficient for the photosynthetic symbionts it may host, but it can also be found in deeper, dimly lit environments.
