Panther Crabs are semi-aquatic and require a combination of land and water in their aquarium. They need a spacious aquarium with a land area, such as a pile of rocks or a piece of wood, for them to climb out of the water and molt. They are omnivorous and will feed on both plant and animal matter, including algae wafers, blanched vegetables, and small live or frozen foods such as brine shrimp or bloodworms.

Water parameters for Panther Crabs should be kept stable, with a pH between 7.0 and 8.0, and temperatures between 72-82°F (22-28°C). They are generally peaceful and can be kept with other peaceful species of fish or invertebrates, but should not be kept with larger, more aggressive fish that may view them as food.

It is important to note that Panther Crabs can be escape artists and will try to climb out of their aquarium if they do not have a secure lid. They can also be territorial and may fight with other crabs if there is not enough space or hiding places in the aquarium. Panther Crabs are often considered a challenging species to keep due to their specific care requirements, but can make interesting and unique additions to a well-maintained aquarium.
