Rainbow Crab Facts & Overview
Typical of crabs, Rainbow Crabs are solitary creatures and get especially crabby (!) as adults. They’ll fight to the death with their own, and really should be kept alone in a tank. Their claws are super strong and sharp, so be careful with your human skin, since you don’t have a carapace to protect yourself.
Appearance
Rainbow Crabs live up to their name, and have vivid coloration, particularly when they’re young and after they molt, sporting a carapace that’s purple and blue and legs and claws that are orange and red.
Habitat and Tank Conditions
As detailed before, Rainbow Crabs need a paludarium setup to satisfy their terrestrial and aquatic needs, and they also need freshwater or brackish water.
Diet
Rainbow Crabs are omnivores and will pretty much eat whatever you give them, though the bulk of their nutrition comes from fruit, plants, and carrion, or waste.
Care
The most important thing you can do for your Rainbow Crab is to make sure they have appropriate water to earth environment that allows them to submerge in water and burrow in the sand.
Breeding
The idea of breeding Rainbow Crabs in captivity is ill-advised both because of the inability to recreate the ocean to sand experience, and also that Rainbow Crabs mate based on lunar cycles and tides that are impossible to connect within a home tank.
Are Rainbow Crabs Suitable for your Aquarium?
