Hermit Crabs


Here’s what you will need to know if you take home a hermit crab:

Crabs become inactive when cold and should be kept in a warm (21-27 degrees) and slightly moist environment (easily monitored with a stick-on thermometer). On cold days use a warm light, heating pad or heating rock.

Fish tanks we recommend for housing, always use lids to keep the escape artists in.

Gravel (washed every few months and dried thoroughly), sand or shell grit (replaced every few months), are great to keep crabs on. Shavings can be sprinkled in one corner of the tank to snuggle in to when cold.

Handle your crab regularly so they get used to it, keep on your flattened palm and off carpet. Crabs are very susceptible to poisoning, so be very careful of any chemicals. The life expectancy of a crab in the perfect conditions is 40 years, so look after them. Hermit Crab Food provides a perfect dry food diet, to which small amounts of most vegetables, fruits and grasses should be added.

Hermit Crab Salt - (table salt has iodine in it) a pinch in a weekly bath is essential for the conditioning of their exoskeleton and cleaning inside the shell. Use Water Ager to remove the Chlorine, Fluoride and heavy metals from the tap water. If the crab does not go into the bath, slowly submerge the crab on his back, gently move him around, remove and place somewhere to dry where the water can run out of his shell.

To breathe crabs need humidity and will suffocate if the environment becomes too dry. Sponge is placed wet in the tank or water bowl and is sucked and provides humidity. The sponge should be rinsed weekly.

A ceramic food bowl is difficult to knock over (less wastage) or chew, and more hygienic. Crabs cannot swim, so drinking bowls must be shallow, or half filled with gravel. The drinking water must be kept fresh. You should provide your crabs with a rock, driftwood or ornament for climbing, which can be re-arranged weekly to keep the environment interesting.

Spare shells (we have fantastic hand painted ones) of a variety of larger sizes should be provided for the crabs to move into when necessary. When crabs molt (and usually eat) their exoskeleton each summer, they re-grow missing legs.
