These Crabs are native to Sulawesi, Indonesia and are best kept as a species only tank but can be kept successfully with livebearers and tetras. Males can be fairly aggressive and territorial so they are best kept as a single or pairs. Avoid stocking them with bottom feeders such as Cory Catfish. Shrimp and Snails can be kept with caution. These colourful inverts grow to 3 inches and display bright orange and red colouration.
