Common name: Touch-Me-Not Sponge

General Information

The Touch-Me-Not Sponge, scientifically known as Neofibularia nolitangere, is a striking species found in the warm waters of the Caribbean Sea and the Gulf of Mexico. This sponge is renowned for its vibrant yellow to orange coloration and its unique appearance, characterized by a massive, irregularly lobed structure that can reach considerable sizes. Despite its beauty, it is infamous among divers and marine enthusiasts for its potent chemical defenses, which can cause skin irritation upon contact.

This sponge plays a crucial role in marine ecosystems as a filter feeder, removing bacteria and organic particles from the water, thus contributing to water clarity and nutrient cycling. Its presence in the hobby is limited due to its defensive nature and specific care requirements, making it more common in public aquariums and research settings rather than home aquariums.

Care

Caring for the Touch-Me-Not Sponge in captivity requires a well-established marine system with stable water parameters. This species thrives in tanks that replicate its natural reef habitat, with plenty of live rock and moderate water flow to facilitate its filter-feeding lifestyle. Due to its sensitivity, it is not recommended for novice aquarists.

Diet and Feeding

As a filter feeder, the Touch-Me-Not Sponge relies on capturing microscopic plankton and organic particles from the water column. In captivity, maintaining a healthy population of plankton and ensuring a continuous supply of dissolved organic material is essential for its survival. Supplemental feeding with specialized liquid foods designed for filter feeders can also be beneficial.

Behavior and Compatibility

The Touch-Me-Not Sponge is a non-aggressive species, but its chemical defenses make it unsuitable for tanks with delicate or sensitive tank mates. Its presence can deter fish and invertebrates that might otherwise graze on or disturb the sponge.

Health and Common Issues

Maintaining optimal water quality is crucial for the health of Neofibularia nolitangere. This species is sensitive to changes in water chemistry and can suffer from tissue necrosis if exposed to poor conditions. Regular monitoring and maintenance of water parameters are essential to prevent health issues.

Habitat

Neofibularia nolitangere is typically found in coral reef environments, often attached to hard substrates in areas with moderate water flow. Its distribution includes the Caribbean Sea and the Gulf of Mexico, where it inhabits shallow to moderately deep waters.
