Step 1 Know that there have been few cases of successful hermit crab breeding. The ideal time is in January and February.
Step 2 Transfer your hermit crabs to an outdoor enclosure to increase the chance of successful breeding.
Step 3 Include a saltwater tank with your hermit crabs to encourage egg laying. Add one teaspoon of salt to every cup of de-chlorinated water in the tank, and maintain a temperature of around 72 to 85 degrees Fahrenheit. The tank will need to have a pump that sprays water and creates a moving water environment for the crab.
Step 4 Create a ramp that leads from the salt water tank to a sandy area.
Step 5 Monitor your female hermit crabs. Her eggs will change color, and when they turn a dark gray color, you can try to dislodge them from the shell and hatch them.
Step 6 Dip the hermit crab's shell carefully in salt water, avoiding getting your hermit crab wet.
Step 7 Gyrate the shell to dislodge the eggs into the salt water.
Step 8 Observe the tiny zoea hatch from the crab's eggs.
Raise Hermit Crab Young
Step 1 Begin feeding the hermit crab young a solution of marine infusoria, a pinch of powdered spirolina, and brine shrimp food daily.
Step 2 Feed your crab young brine shrimp and a pinch of spirolina after they are seven days old.
Step 3 Know that it's recommended that you add thawed zoo-plankton food to the tank daily to contribute to the larvae's nutrition.
Step 4 Select tiny conical shells for your hermit crabs after the 14-day point.
Step 5 Provide fine-grained sand on the connecting platform of your salt water tank. The hermit crabs will begin to go on land.
Step 6 Provide shallow dishes of fresh water for your hermit crabs at this point in their development.
Step 7 Add the hermit crabs to a traditional hermit crab enclosure after day 40.
