I have two Purple Short Spine Pincushion Urchins for sale. I actually have 3 and they have eaten up all the algae in my tank. I'd like to keep one for maintenance. They are medium sized I would say, maybe about 2" across. They mow through Bryopsis like it's not even there.

I paid $20 each, selling for $10 each.
