This is a Nano/Pico sized pencil urchin, Eucidaris tribuloides from the Caribbean. They eat algae from the rocks and the walls of your tank. They are not considered reef-safe.

Got one as a hitchhiker on a live rock order. Survived the shipping. Was on the bottom, thought he was dead, but put him in a bucket of water and he moved around. Put him in tank, and he wanders around, sometimes hard to spot, but I have a lot of nooks and crannies. Not out in the open much, but spot him every once in a while

I received one of these guys free, and it is a beautiful specimen, thank you.

Very nano, but this is exactly what I was looking for. Probably the size of a dime. If you want bigger, get the standard size, but I love this little guy.

When they say nano they mean nano. About the size of a dime, but a great add to the tank. Already wandering around.

This is one of the coolest animals I have added to my reef! I really wish I had ordered two! It arrived well packed and was active immediately after being temp acclimated. I was amazed that it is able to climb vertically and hang on in the high flow. Very cool and interesting critter!

Awesome litte guys! The 4 I received are out at all tiems, day or night, and are really mobile. One seems to enjoy a good tumble across the sand every now and then, on purpose. They even go after the coraline algae starting on teh glass. Fascinaing to watch.

I got four of these little guys to tackle an algae problem in one of my nano tanks. They went to work immediately along with some snails I got, and the algae has already diminished greatly in a week’s time!

I’m amazed that they can get into the smallest crevices. Fascinating to watch, but mostly hide when the lights are on.
