Mespilia sp.

Datasheet

General Description

The Tuxedo Urchin, scientifically known as Mespilia sp., is an easy-to-care-for marine creature popular as part of a cleanup crew in aquariums. With oval or round bodies covered in hundreds of sharp, uniform spines, these urchins are typically black in color and can reach a maximum size of 7.6cm. They are herbivores, actively scavenging for food and algae over rocks and substrate in their environment.

Aquarium Suitability

The Tuxedo Urchin is well-suited for aquariums, particularly for aquarists looking for low-maintenance species. They are peaceful in temperament and can be housed with other tank mates as long as sufficient food and shelter are provided. However, they are sensitive to copper-based medications and high nitrate levels, which can lead to the loss of spines. A minimum tank size of 75 liters is recommended for keeping Tuxedo Urchins.

Care and Hardiness

Being easy to care for, Tuxedo Urchins require a stable environment with suitable water conditions. They thrive in a pH range of 8.1-8.4, a specific gravity of 1.023-1.025, and a carbonate hardness (KH) of 8-12. Supplementing their diet with dried seaweed is essential if algae levels in the aquarium are low. Regular monitoring of water parameters is crucial to prevent stress-related issues.

Reef Suitability

Reef hobbyists will find the Tuxedo Urchin compatible with reef aquariums, as they are reef-safe and will not harm corals or other invertebrates. Their herbivorous diet helps in maintaining algae levels within the reef tank, benefiting the overall ecosystem. However, caution should be exercised with delicate corals, as the spines of the Tuxedo Urchin can puncture unprotected flesh.

Aquarium Setup

When setting up the aquarium for Tuxedo Urchins, provide ample hiding spots among rocks, crevices, or under plants in a sandy substrate. Ensure a diverse range of algae for grazing and maintaining optimal water quality. Regular water changes and the addition of supplements like calcium, magnesium, iodine, and trace elements are recommended to support their health and shell development.

Behaviour

During the day, Tuxedo Urchins are often found hiding among the aquarium structures, while they emerge at night to feed on algae. They usually roam alone but can coexist with others of their kind in larger aquariums. Their peaceful nature makes them a suitable addition to community tanks, adding interest and aiding in algae control.

Feeding and Diet

As herbivores, Tuxedo Urchins primarily feed on algae and detritus present in the aquarium. In cases of low algae levels, supplement their diet with dried seaweed strips or other suitable algae-based foods. Maintaining a well-balanced diet is essential for their overall health and vitality.

Habitat and Distribution

Tuxedo Urchins, belonging to the family Temnopleuridae, are found in various marine habitats across the world. Their distribution ranges from tropical to temperate regions, where they play a significant role in maintaining the ecological balance by consuming algae and detritus. Aquarists can replicate their natural habitat by providing a stable environment with appropriate hiding spaces and food sources.
