Common name: Urn Sponge

General Information

The Urn Sponge, scientifically known as Leucilla nuttingi, is a small but fascinating sponge species found in the marine aquarium trade. It is recognized for its delicate tubular structure and white coloration, making it a subtle yet intriguing addition to marine setups. Sponges like Leucilla nuttingi play a crucial role in the ecosystem as filter feeders, helping to maintain water quality by removing small particles and bacteria.

While not as commonly kept as fish or corals, Urn Sponge is appreciated in the hobby for its unique appearance and ecological benefits. It can be a good choice for advanced aquarists who are interested in creating a more natural and balanced aquarium environment.

Care

Caring for Leucilla nuttingi requires attention to water quality and flow. These sponges thrive in well-established aquariums with stable parameters. They require moderate to strong water flow to help them filter feed effectively, and pristine water conditions to prevent clogging of their delicate structure with detritus or algae.

Lighting is not a significant concern for Urn Sponge, as they do not rely on photosynthesis. However, indirect light can help prevent algae overgrowth on the sponge's surface.

Diet and Feeding

As filter feeders, Urn Sponge relies on capturing microscopic particles from the water column. In a well-maintained reef tank, they can survive on the natural supply of plankton and dissolved organic material. However, supplemental feeding with liquid plankton or specialized sponge foods can support their nutritional needs.

Behavior and Compatibility

Urn Sponge is non-aggressive and can coexist peacefully with a wide variety of reef-safe fish and invertebrates. They do not pose any threat to other tank inhabitants and can be included in a community tank setup.

Health and Common Issues

The primary concern for Leucilla nuttingi is maintaining water quality. These sponges are sensitive to poor water conditions, which can lead to tissue degradation or death. Regular water changes and careful monitoring of nutrient levels can help maintain their health.

Habitat

Urn Sponge is found in shallow marine waters, often attached to rocks or coral substrates. They are distributed across the Caribbean and parts of the Western Atlantic Ocean. In the wild, they inhabit areas with good water movement, which aids in their filter-feeding lifestyle.
