Long Spine Urchin

Quick Stats

Description

The Long Spine Urchin (Diadema setosum) is a unique and eye-catching invertebrate that adds intrigue to any marine aquarium. Known for its extremely long, black spines, this urchin serves as both a stunning visual addition and a useful algae grazer. These sharp spines provide protection, and though they are not poisonous, they can cause irritation if handled improperly. Native to the Indo-Pacific region, the Long Spine Urchin can help maintain a clean tank by feeding primarily on algae, keeping it in check. While its diet makes it beneficial for reef tanks, caution is needed, as its sharp spines can harm corals and other delicate tank mates if not given enough space. It is best to provide ample room to roam and hide, and due to its semi-aggressive nature, it should be housed with similarly sturdy species. The Long Spine Urchin requires a stable environment with excellent water quality to thrive. Regular monitoring of water parameters is essential for its health. This species can grow up to 10 inches in diameter, including the spines, so a larger tank (at least 125 gallons) is recommended. In summary, while the Long Spine Urchin is an excellent algae grazer and can be an interesting centerpiece in a large, well-established reef system, it should be handled with care and caution due to its size and potential for damaging corals.
