Creating the Perfect Home: Red Claw Crab Habitat Essentials

Updated: Apr 12

Red claw crabs are a excellent addition to your aquarium. However there are some special considerations that need to be made before adding one of these crabs to your aquarium.


Do Red Claw Crabs Need Land?


one of the special considerations for keeping red claws is their need for dry land. +


Red claw crabs are semi-aquatic creatures, meaning they require access to both water and dry land. Failing to provide them with a suitable area to exit the water in your aquarium can result in serious consequences, potentially leading to the death of the crabs.


Ideally, you should keep the water to land ratio around 3 to 1. That means the habitat should be primarily water with some chunks of land for the crab to relax on. This can be accomplished with the use of one of our underwater island habitats.

Red claw crabs are omnivores and scavengers. This means they will eat any dead fish or dead plants. The can also be fed fish flakes and pellet food. Crab specific pellets that sink fast are a great choice for these crabs.


We like to provide our crabs with live crickets. Using one of specially designed feeder tubes we can place a cricket inside the underwater island habitats where they can move around and provide a nice active food source for our crabs.


How Often Should I Feed Red Claw Crabs?


Feeding your red claw crabs can be a daily occurrence. especially if the crabs have fish for tank mates. These crabs will enjoy any of the leftover food that have sunken to the bottom of the tank.
