General Description
Sally Lightfoot Crabs, scientifically known as Percnon gibbesi, belong to the Majoidea family Percnon. These crabs can grow up to 10.0cm in size and are commonly found in the East Indian Ocean and the Mexican Gulf. Known for their hardiness, they are characterized by their vibrant colors, typically red, orange, or yellow.
Aquarium Suitability
Considered suitable for most aquariums, Sally Lightfoot Crabs can be a good addition to the tank. However, caution is advised as they can pose a threat to small fish, crustaceans, and corals, especially when they reach their full size. Their temperament may lean towards aggression when interacting with other species in the aquarium.
Care and Hardiness
Sally Lightfoot Crabs are known for their hardiness, making them relatively easy to care for in a suitable aquarium environment. They can thrive within water conditions with a kh range of 8-12, pH levels between 8.1-8.4, specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6°C.
Reef Suitability
Labeled as reef safe with caution or luck, these crabs can be compatible with reef environments, but their interactions with corals and other reef inhabitants must be carefully monitored to prevent any harm to the ecosystem.
Aquarium Setup
When setting up the aquarium for Sally Lightfoot Crabs, ensure a minimum tank size of 200 liters to provide ample space for their movements. Incorporate rocky structures and hiding spots in the tank to mimic their natural habitat and offer them areas to explore and retreat to when needed.
Behaviour
These crabs are known to be active and agile, constantly scavenging for food and exploring their surroundings. While they may exhibit territorial behavior and aggression towards other tank mates, providing sufficient space and hiding spots can help minimize conflicts.
Feeding and Diet
Their diet should consist of a variety of foods, including detritus, macroalgae like seaweed or nori, microalgae such as spirulina, and small crustaceans like krill, mysis, and artemia. Offering a diverse diet will help maintain their health and ensure their nutritional needs are met.
Dimorphism
Sally Lightfoot Crabs do not exhibit significant dimorphism, with males and females generally appearing similar in size and coloration. In a captive setting, they have the potential to reproduce under suitable conditions, although specific details on their captive reproduction are not covered in available information.
Habitat and Distribution
In the wild, these crabs are commonly found in the rocky intertidal zones of the East Indian Ocean and the Mexican Gulf. They prefer habitats with ample hiding spots and crevices to retreat to for protection and foraging opportunities.
