General Description
The Variegated Pincushion Sea Urchin, scientifically known as Lytechinus variegatus, is a species originating from the tropical waters of the Western Atlantic. With a peaceful temperament, this tan-colored sea urchin serves as a natural solution for managing nuisance algae in reef aquarium systems.
Aquarium Suitability
The Variegated Pincushion Sea Urchin is suitable for reef aquariums and can aid in keeping the tank environment healthy and clean by rapidly consuming unwanted algae.
Demands, Care, and Hardiness
Requiring moderate care, this sea urchin thrives in aquariums with stable live rock formations that provide hiding spots and room for foraging. It is mainly active at night, seeking food, and may conceal itself during the day. Stable water conditions with a pH of 8.1-8.4, a specific gravity of 1.023-1.025, and a carbonate hardness (KH) of 8-12 are essential for its well-being.
Reef Suitability
The Variegated Pincushion Sea Urchin is reef-compatible, making it a viable addition to reef tank setups.
Aquarium Setup
To house the Variegated Pincushion Sea Urchin adequately, aquarists should ensure the presence of ample live rock for hiding and foraging opportunities. Stable rock formations capable of withstanding the urchin's movements are crucial. Regular monitoring of water quality is necessary as this species is intolerant to high nitrate levels and copper-based medications.
Behaviour
In the aquarium, this sea urchin displays interesting covering behavior, possibly for camouflage or UV protection, by gripping small rocks, shells, or pieces of macroalgae with its tube feet. While generally solitary, the Variegated Pincushion Sea Urchin can coexist with others of its kind if sufficient space and food are available.
Feeding and Diet
As a herbivore, the Variegated Pincushion Sea Urchin primarily feeds on algae. In environments where algae are scarce, its diet should be supplemented with dried seaweed to ensure proper nutrition.
Habitat and Distribution
In the wild, the Variegated Pincushion Sea Urchin is commonly found in shallow sea grass flats and sandy substrates in the tropical waters of the Western Atlantic.
