Looking for an easy-to-care-for addition to your cleanup crew? The Red Tuxedo Urchin will scavenge over rock and substrate for bits of food and algae to eat. The Red Tuxedo Urchins have oval or round bodies covered with hundreds of uniform spines. Though the spines are short, they are still sharp, and can puncture skin.

During the day, it will hide among the rocks, in crevices, or under plants in a sandy substrate. At night, it will emerge to graze on the algae present in or near its home. The Tuxedo Urchin generally roams alone, but several of them could be housed in the same aquarium if it is large enough to provide them with adequate food (algae) and shelter. It is sensitive to high levels of copper-based medications and it will not tolerate high nitrate levels. If it starts to lose a number of spines, it is often due to poor water conditions.

If algae levels are particularly low, its diet will need to be supplemented with dried seaweed.

Approximate Purchase Size: Small: 1" to 1-1/2"; Medium: 1-1/2" to 2-1/2"

Customer Testimonials

Great creature! Although it is very slow, it is fun to watch. It is completely reef safe. I would advise buying this exotic urchin!
Heather Z San Jose , CA
Love this little guy! Had it a week and it acclimated well and is doing great. I think it may have even grown some already! It decorates itself with bits of sand as it goes back and forth across the rock.

Read Completely: These are really cool creatures to watch in the tank. They move around a lot and gather a bunch of material in the tank as camouflage. I have own 2 of these and I would recommend caution. Both were in a fairly new tank 6m and 3m old. I would recommend holding off until a year or so as small parameter changes can kill these creatures. Urchins are very sensitive to small changes in water quality. If you have a problem, you will notice they will fall from the wall and shrink up. That is followed by spines falling off and eventually death. These may be easy to keep, but I do not recommend them in a newer tank. Make sure your water parameters are very stable before introduction to your tank.
