Common name: Rosario's Sponge

Scientific name: Neopetrosia rosariensis (Zea & Rützler, 1983)

General information

Neopetrosia rosariensis, commonly known as Rosario's Sponge, is a species of marine sponge found in the Caribbean Sea. This sponge is notable for its vibrant coloration, which can range from bright yellow to deep orange, making it a visually appealing addition to any reef aquarium. It has a firm, yet slightly compressible texture and a semi-encrusting growth form that can add a unique structural element to the tank.

Care

Rosario's Sponge requires a moderate level of care. It thrives in well-established aquariums with stable water conditions and strong water flow, which helps to deliver the planktonic food it filters from the water. It is important to maintain high water quality, as sponges are sensitive to elevated levels of nitrates and other pollutants. Targeted feeding with fine particulate foods can supplement its diet.

Reproduction

In the wild, Neopetrosia rosariensis reproduces both sexually and asexually. Sexual reproduction involves the release of gametes into the water column, while asexual reproduction occurs through budding or fragmentation. In the aquarium, fragments that break off can sometimes attach to the substrate and grow into new individuals.

Symbiosis

Rosario's Sponge does not have any well-known symbiotic relationships that are of particular interest to reefkeepers. However, like many sponges, it can play a role in the tank's ecosystem by filtering water and providing microhabitats for small organisms.

Habitat

Neopetrosia rosariensis is typically found in shallow waters of the Caribbean Sea, often attached to hard substrates such as rocks or coral rubble. It is adapted to a range of light conditions but does not require direct lighting in the aquarium, making it suitable for placement in lower light areas.
