Geosesarma crabs- a strikingly beautiful addition to a vivarium
A good friend of mine, Bill Brissette of mellowvision.com, has been working with these beautiful little crabs for quite awhile now. He now has multiple generations of the crabs in his tank, and I was blown away by their beauty and behavior when I recently paid his fish room a visit.
These crabs do best in a set up similar to what would be used for dart frogs- high humidity and lots of emergent plants. Bill has his set up with a great rainbar and water feature. You can see more details either in the four part series he did for TFH last summer, or at his website.
Geosesarma crabs are omnivores, with most interest being shown towards small live insects and prepared foods like crab pellets . They do well in groups, with enough cover and appropriate water feature, and do breed in captivity when their needs are met.
Bill has many F1 juveniles and subadults available for sale!
Here is a video that Bill took of his crabs.
And the crabs caught in the act of mating!
