The Red Devil Crab arrived quickly and looks exactly as described. It’s very active and adds a lot of color to the tank. I’ve kept it for three months and it’s thriving.

Great addition to my aquarium. The crab is bold and curious. I noticed it digs in the substrate and interacts with other tank inhabitants. A bit more maintenance than expected, but worth it.
