The Pencil Urchin (Eucidaris tribuloides) is sometimes called a Mine Urchin or a Club Urchin. It belongs to the family named Cidaridae. Typically reaching a max size of about 5 inches in diameter, the Pencil Urchin is passive in nature and moderately hardy in stamina. It's more active during the evening hours or at night and less so during the day, and will hang out or do best in the rock structures. According to FishDB current data, captive breeding success is unlikely and there are no external signs of sexual differences. Tank parameters should be maintained with ph level between 8.1 - 8.4, temperature between 77 - 79 degrees fahrenheit, and a salinity between 1.020 - 1.023. Some of the environmental concerns that you should strive to replicate in your home aquaria to promote succesful acclimation include a well established aquarium, high water quality, porous live rock, rockwork structure, and plenty of hiding spaces.
