Your aquarium temperature should be 75 to 85 degrees, and keep 60 to 70 percent humidity.

How do hermit crabs breed in captivity

How do hermit crabs breed in captivity?

Hermit crabs are delivered to the oceans. Females lay eggs in the oceans, and the strongest eggs develop into hermit crabs.

It would be best to keep a mature female in a breeding tank. This tank should be full of saltwater-like oceanic water and add a mature and sexually fit male crab. It may take a partner selection before a female agrees to breed.

Hermit crabs Breeding process:

The breeding process can differ in different species depending on the size and species. 

Following steps are included in the breeding process.

  1. Female releases a pheromone, which shows that she is ready to breed.
  2. Males identify these pheromones and approach them.
  3. The male hermit crabs struggle with who will breed with the female.
  4. When the male wins, then the female shows interest.
  5. If the female is ready to breed, the male starts mating.

Hermit crabs usually mate in their shell to save themselves. A male has a large penis which ensures that the female can be implanted easily without leaving the shell.

During mating, the male transferred spermatozoa into the female’s gonopore. If fertilization occurs, the eggs remain in the female’s body for a month and are then released.

Molting: Purple Pincher Hermit Crab

When purple hermit crabs are fully grown, the shell that they have shed comes off. It is common for young hermit crabs to molt multiple times, compared to adults, who can only molt between 12 and 18 months of age.

When crabs molt, they burrow themselves under the earth sometimes for a few days, but sometimes for up to eight weeks. When your hermit crabs molt, the old skeleton will rupture, and the crab will leave the old exoskeleton.

To minimize stress, leave your hermit crab alone until it relaxes. When molting is complete, put your crab’s shell into the tank because the crab mostly eats its old shell.

Changing shell

Changing shell:

When you decide to keep hermit crabs, you should ensure that you have every type of shell so that the crab feels comfortable when it is ready to grow.

Purple hermit crabs alter their shells often if they can’t find the shell they are searching for. So it is important to have many types of shells. You can read about the hermit crabs without shell here.

The more crabs you have, you should have more shells because crabs fight for the prized shell.
