Overview: Heterocentrotus spp., commonly known as slate pencil sea urchins, are distinctive marine invertebrates prized for their robust spines and unique appearance. Available in various sizes, these urchins add natural beauty and interest to marine aquariums.
Care Level: Moderate. These urchins require stable water conditions and a well-established tank.
Diet: Primarily herbivorous, feeding on algae and detritus. Supplement with dried seaweed or specialised invertebrate foods if natural algae is insufficient.
Compatibility: Generally peaceful but may compete with other grazing invertebrates. Avoid housing with predatory fish or invertebrates that may harm them.
Reef Safety: With Caution. While they are mostly reef safe, their strong spines can damage delicate corals if not monitored.
Tank Requirements: Minimum tank size should be at least 100 litres to provide adequate space. Maintain stable water parameters with good filtration and moderate water flow.
Placement: Provide rocky areas or crevices for shelter and grazing surfaces. Ensure the aquarium has ample live rock to support natural feeding behaviour.
Additional Notes: Handle with care due to their sharp spines. Regular monitoring is advised to ensure they do not overgraze or disturb other tank inhabitants.
