Nice size, very neat, as soon as they were released they were moving around.
I order two and they both came in at a good size, they love to eat Algae from my live rocks.
Urchin arrived promptly overnight in a sealed bag in perfect condition. She seems pretty alive and has been crawling all over my tank. Great addition
These are the most hardy urchins that I have ever seen. They seem to be very touch and went to work eating algae in my tank right away, after a several hours of drip acclimation of course.
Ordered two, both nice size and running around the tank already
