I have two white, pincushion type, urchins that I added to my tank several months ago. They have done their job and are now probably not getting enough to eat. They are reef friendly and do not eat coral. They devour hair algae and probably other algae too. I am going to let one go for now and likely let the other one go in the near future.
If anyone has a need for one and would like to trade a frag of something let me know.
If you don’t have a frag but really need it let me know.
Wilmington, near limestone road and kirkwood Highway
