Coloured Short-Spine Urchin

The Coloured Short-Spine Urchin (Hemicentrotus pulcherrimus) is a striking marine invertebrate known for its vibrant coloration and unique spiny appearance. Found primarily in the shallow waters of the Indo-Pacific region, this species of sea urchin plays a crucial role in maintaining the health of coral reef ecosystems, where it grazes on algae and detritus. Its beautiful hues range from deep blues and purples to bright greens and yellows, making it a visually appealing addition to any marine display.

These urchins typically inhabit rocky substrates and coral reefs, where they can find ample food sources. Their bodies are covered in short, sturdy spines that provide both protection from predators and aid in camouflage among the reef's crevices. The Coloured Short-Spine Urchin is known for its ability to adapt to various environments and can thrive in diverse marine conditions, showcasing a hardy nature that appeals to aquarists.

In terms of behavior, this species is generally peaceful and tends to be more active during the day, foraging for food. They are known to exhibit interesting behaviors such as burrowing into crevices or hiding under rocks, which adds to their charm in an aquarium setting. Their grazing habits contribute to algae control, helping maintain the balance of the tank's ecosystem.

Overall, the Coloured Short-Spine Urchin is not just an attractive addition to marine tanks, but also a functional one, providing ecological benefits while enhancing the aesthetic appeal of the aquatic environment.

When caring for the Coloured Short-Spine Urchin, it is essential to maintain stable water parameters to ensure their health and longevity. Ideal water temperature ranges from 24 to 28°C, with a pH level between 8.1 and 8.4. Although this species can tolerate a variety of salinity levels, it thrives in marine environments with salinity levels of 30-35 ppt. A minimum tank size of 100 liters is recommended to provide adequate space for grazing and hiding.

Feeding the Coloured Short-Spine Urchin involves a diet rich in algae and detritus. They can be supplemented with blanched vegetables like spinach or specialized algae wafers to ensure they receive adequate nutrition. Compatibility is generally good with other herbivorous and peaceful marine species, but caution should be exercised with predatory fish that may view them as food.

Acclimation should be done slowly to reduce stress, ideally over several hours with gradual changes in water chemistry. Quarantine procedures are advisable to prevent the introduction of any pathogens into the main aquarium. Ensuring a clean and stable environment will promote the health and vibrancy of these beautiful sea urchins.

The Coloured Short-Spine Urchin is suitable for shipping due to its robust nature. It is recommended to pack them in breathable containers with plenty of water to maintain humidity. A shipping temperature between 20-24°C is ideal to minimize stress during transport. As there are no CITES restrictions for this species, they can be exported without special permits, making them an appealing choice for wholesalers.
