Amazing Facts

·        The Coenobitidae, which includes land-dwelling Hermit Crabs, is one such family. The remaining six families are known as aquatic animals.

·        Hermit Crabs, unlike many other decapod crustaceans, have a soft abdominal area. To shield themselves, they have evolved curved bodies that fit into mollusk shells that have been scavenged.

·        In the wild, hermit crabs are usually peaceful and social creatures who live in large groups.

·        Smaller reef-friendly species are generally peaceful, but you can note that they compete with one another. Rapping is a term that describes this type of action (which essentially is a battle to get another crabs shell).

·        Larger species will be more aggressive than smaller species, and your fish will be attacked.

·        This form of action can be avoided by spreading a number of different sized and shaped shells across the substrate. They prefer to hang out in the lower parts of the tank. They are, however, successful climbers and can be found on live rocks in between the reefs.

·        Gills are used by both marine and land animals to breathe. Land species breathe air and may die if left in water, while marine species exchange carbon dioxide for dissolved oxygen in the water column.

·        As they grow, they need larger shells, which they typically steal from other crabs.

·        They shed their exoskeleton as they grow, as do all crustaceans. Since the rate of growth slows dramatically with age, younger specimens lose their exoskeleton more than adults.

·        Their soft, asymmetrical abdomens need protection from a shell. They become vulnerable to predation when they lose their shell.

·        The majority of Hermit Crabs have one trait in common. They have long, soft abdomens that are spirally curved to allow them to anchor themselves inside mollusk shells that have been scavenged. The shape of their shell isn’t particularly important because they change shells when they get too big for the previous one.

·        Both Hermit Crabs are members of the Decapoda order, which means “ten-legged.” Their claws are one of ten appendages on their body.

·        Along tropical coastlines, land species can be found. Their gills must be kept moist in order to breathe, so they must be near the ocean or freshwater streams. They breed in shallow saltwater as well.

 ·        The Halloween Hermit is a water-dwelling animal that spends its entire life in the Indo-Pacific Ocean. The water temperature ranges from 71 to 83 degrees Fahrenheit, with a pH of 8.1 to 8.4. The real gravity ranges from 1.020 to 1.025.

·        Even for accomplished hobbyists, breeding Hermit Crabs can be extremely difficult.

·        The simple part is getting them to breed.

·        The issue is actually with the upbringing of the children. Since they develop planktonic larvae like all crustaceans, breeding them in an existing reef system is simply not a choice.

·        Molting is the mechanism by which an organism sheds its exoskeleton.

·        They do this because their hard exoskeleton does not expand with them as they grow, so they must remove it to allow them to grow larger.

·        Every 18 months, healthy specimens shed their exoskeleton. Juveniles, on the other hand, moult once a month before they reach maturity.

·        They will become slightly duller and less vibrant prior to the moulting process.

·        If you remove their exoskeleton from the tank after they’ve shed it, they’ll start eating it because it’s full of calcium that’s needed to reinforce their new exoskeleton.

·        You should also start supplementing them with calcium-rich foods at this stage.

·        Hermit crabs can be found in a variety of habitats around the world (both land and ocean systems).

·        Make sure you do a lot of homework about how to care for a crab before taking one home.

·        If their needs aren’t met, they may become stressed, which makes them more susceptible to infection and disease.
