The Radiata Urchin looks stunning in my 50-gallon tank. It’s peaceful and doesn’t bother the corals. It’s been two months and it’s growing steadily. Easy to maintain with regular water changes.
Trevor Simpson –
Arrived healthy and active. The red and blue spots are very visible. I’ve kept it in a reef tank with soft corals and it’s coexisting well. A good addition to a mid-level reef setup.
Edward Bailey –
Great choice for intermediate reef keepers. It’s not aggressive and stays in one spot. Water parameters are stable, and it’s been thriving since arrival.
