Rearing Geosesarma offspring to maturity from birth is perhaps one of the biggest issues with establishing captive populations with the current means of raising them. The standard practice is to not sepeate all young from adults or one another, but this leads to predation, cannibalism, and damagae of freshly hatched Geosesarma offspring.
The TGD team has begun to seperate nymphs into delicups with approximately 1oz of water and a piece of corkbark for a land feature. So far this practice has lead to pehonomenal reduction of deaths of Geosesarma offspring. Cannibalism and damage from agression towards young nymphs is impossible when they are separated. They can be kept in groups in larger cups or solitary in individual small delicrups such as shown to the side in a 5oz delicup.
Beyond just the reduction of cannibalism, separating the Geosesarma when young has lead to a heigtenined ability to confirm that all offspring are eating regularly and the ability to manage and record individual molting behavior as well.
One other method for rearing and propagating Geosesarma is described by Hohle & Singheiser (2016) in their book Keeping and Breeding Vampire Crabs of the Genus Geosesarma where great success has been had in seperating gravid females into their own seperate tubs of at least 5.0 liters until they give birth to live crabs. Tubs are set up very much the same as regular Geosesarma enclosures only just on a smaller scale but the water section should be at least 1 liter. After the female has given birth she can be returned to her original enclosure. A fairly large number of these crabs can be kept together and will be much safer from cannabalism from larger uvenilles and adults, but as they grow larger getting into the juvenille stages Hohle & Singheiser (2016) reccomend splitting the rearing groups into around 10x juvenilles in well structured and laid out tubs until they start obtaining their adult coloration at the age of about a year.
