The crab arrived healthy and active. It has adapted well to our 10-gallon tank with live plants. It spends most of its time near the back wall, exploring the rocks. Very easy to care for and adds a lot of visual interest.

We’ve had the crab for three months now. It’s calm and doesn’t seem to stress other fish. The color is more vivid than expected. A great addition to a freshwater setup.

First time keeping a crab in the tank. The purple color stands out beautifully. It’s curious and active, especially during the morning hours. Water parameters stayed stable with regular testing.
