The Purple Pincushion Urchin has been thriving in my 40-gallon reef tank for six months. It’s peaceful and doesn’t interfere with other corals. Easy to maintain and looks beautiful with the colorful reef environment.

I added this urchin to my intermediate reef setup. It’s active but not aggressive. The tank size is sufficient, and it has adapted well to the water parameters.
Justin Hamilton –
Great addition to a reef tank. It’s hardy and stays calm around other invertebrates. I appreciate the clear care instructions and the fact that it’s reef-safe.
