Tank compatibility[edit | edit source]
Diet[edit | edit source]
- This is an omnivorous Urchin. It will graze on algae and can be supplemented with dried seaweed. It may also eat sessile invertebrates.
Feeding regime[edit | edit source]
This Urchin needs a constant supply of algae or can be supplemented with dried seaweed daily.
Environment Specifics[edit | edit source]
- It is sensitive to high levels of copper-based medications and it will not tolerate high nitrate levels. It needs a well established tank with lots of live rock for grazing and hiding. It is also a perfect addition to a tank with aggressive fish to control algae. Poor water quality will cause it to lose all of its spines!
Behaviour[edit | edit source]
Peaceful but it may eat some soft or hard corals and sessile invertebrates if there isn't enough algae or dried seaweed provided. Sturdy rock work is a must as it may topple lose rocks while grazing. It is generally solitary, but will tolerate others of its own kind.
Identification[edit | edit source]
Color ranges from purple, white, blue and red. Short spines and visible tube feet. It is round or oblong in shape. The tube feet are aligned in five doubled rows.
