Common name: Lollipop Tunicate

General Information

The Lollipop Tunicate, scientifically known as Nephtheis fascicularis, is a captivating marine invertebrate that has piqued the interest of advanced aquarists and researchers alike. Its unique appearance, resembling a cluster of lollipops on a stick, makes it an intriguing addition to specialized reef aquariums. This species is not commonly found in the average home aquarium due to its specific care requirements and rarity in the trade.

These tunicates are part of the ascidian group, which are sessile filter feeders. They play an important role in their natural habitats by filtering plankton and other small particles from the water, thus contributing to the clarity and quality of their environment.

Care

Caring for the Lollipop Tunicate requires a well-established aquarium with pristine water quality. They thrive in environments with moderate to strong water flow, which helps deliver the plankton they feed on. Due to their specific dietary needs, they are best suited for mature aquariums that can support a healthy population of microplankton.

These tunicates are sensitive to changes in water parameters, so maintaining stable conditions is crucial. They do not tolerate poor water quality, and sudden changes can lead to their decline.

Diet and Feeding

Lollipop Tunicates are filter feeders, relying on a diet of plankton and other microscopic particles. In captivity, they require regular feedings of marine snow or phytoplankton supplements to meet their nutritional needs. Providing a consistent supply of these foods is essential for their survival.

Behavior and Compatibility

Lollipop Tunicates are non-aggressive and can be housed with a variety of other peaceful marine species. They do not pose a threat to other tank inhabitants, making them suitable for community reef tanks. However, their specific care requirements mean they are best kept by experienced aquarists who can cater to their needs.

Health and Common Issues

Maintaining the health of Lollipop Tunicates involves ensuring stable water conditions and a consistent food supply. They are susceptible to poor water quality and may deteriorate if their environmental needs are not met. Regular monitoring of water parameters and careful feeding are key to preventing common issues.

Habitat

Nephtheis fascicularis is typically found in tropical and subtropical waters, often inhabiting coral reefs and rocky substrates. They are distributed across the Indo-Pacific region, where they contribute to the biodiversity of reef ecosystems by acting as natural water filters.
