I’ve had my Mexican Red Leg Hermit for three months now. It’s very active and keeps the tank clean by eating algae and leftover food. I added several empty shells and it’s been using them regularly. It’s colorful and adds a lot of personality to the tank.

The crab is hardy and easy to care for. I noticed it spends most of its time moving around the live rock. I didn’t have to worry about it eating snails after adding extra shells. A great choice for a beginner saltwater keeper.

It’s been a joy to watch. The red legs stand out in the tank and it’s always active. I keep it in a 55-gallon tank with plenty of rock and sand. It’s not aggressive and seems happy with the setup.
