Red Devil Crab - Geosesarma Sp.
The Red Devil Crab is a striking semi-terrestrial invert.
They are fairly new to the hobby and do well with shrimp and larger snails though it's recommended to give them 50% land in their tank to mimic their natural habitat.
A 50/50 setup of land and water would be preferable with some area with sand so they can burrow.
These crabs love to eat a good mix of meats and vegetation along with just about anything else that is aquatic food (variety is key to good health).
Fully grown, they reach about 2" - 2.5" on average.
