Natural sea sponges are NOT bad for hermit crabs. In fact, they are a great food source. “But your website says not use to use sponges!” Yes. It does. However, there is some need for clarification here. The more accurate statement would be: Do not use sponges in the manner suggested by the pet store or packaging. Most pet stores and pet supply stores sell sponges as a multipurpose product. First, as a means of drinking without drowning. That, in and of itself, is amusing considering most pet stores don’t provide enough water for a fly to drown in let alone a hermit crab. HermitRead More →

There seems to be some controversy and confusion regarding the need for UV-B lighting with hermit crabs. Due to the esoteric nature of our chosen pets, few studies are available to draw from which explicitly study hermit crabs. There is however a considerable volume of research regarding crustaceans, and more specifically decapod biology available to study.Read More →

Why are hermit crabs hairy? Those little ‘hairs’ you see all over the body and chelipeds of your hermit crab are not hairs at all. They are an extension of the exoskeleton and are called setae. A seta is an elongate projection with a more or less circular base and a continuous lumen; the lumen has a semicircular arrangement of sheath cells basally.

The Land Hermit Crab Owners Society recommends that hermit crabs only be removed from their habitat for an occasional visual inspection or photo. This is one of the most contested recommendations in our community. The LHCOS recommendation is based on what research has taught us thus far. We are still learning, research is still being conducted and we are following it closely. Land hermit crabs require humid air to breathe. When the relative humidity drops below 70% the gills begin to dry out. Over time the gills will become irreversibly damaged. How much damage they can sustain before death is not known.

We all go on vacation  or have to be away from home for an extended period at some point. Your hermit crabs will need someone to check on them at least once during a seven day absence. Ideally someone can check on them every other day but not everyone is able to arrange a regular check in. Be sure to write up an instruction sheet for your pet sitter. Include a link to this website, our emergency form and even our Facebook group so that we can help them if they need us. If your sitter isn’t a crab keeper they may have trouble rememberingRead More →

Written by Anne Grady Food mites, more properly called grain mites are something that can be found in any tank at any time. The first thing to understand is that they did not come from the crabs, having hermit crabs does not cause you to have food mites. Food mites come into your home through the everyday things you buy at the grocery store. Anything that contains grain can have food mites. Oatmeal, grits, breakfast cereal, noodles, flour and rice are a few examples. In general you won’t see them and they are harmless, but that box of corn meal or pancake mix that getsRead More →

A hermit crab’s shell is his life sustaining home and his protection from predators and desiccation. Hermit crabs take up residence in discarded gastropod shells and can not make their own shell. “For the vast majority of crustaceans which we call hermit crabs, the behavior patterns by which individuals utilize empty gastropod shells as shelter are critical to the crab’s existence. Orientation to shells, selection of a shell to enter, entry of a shell, and subsequent living the shell are all behaviors which directly affect the Darwinian fitness of an individual crab. Failure to find or efficiently enter a shell at all can rapidly andRead More →

Let’s look at how to set up a proper hermit crab habitat, which we refer to as a crabitat. Basing your tank set up on what you saw at the petstore or mall cart where you may have purchased your hermit crabs is a recipe for disaster. Kritter Keepers and wire cages are death boxes and should never be used. Listed below are the primary components of a proper set up and we will discuss them in detail. If you are not willing to equip the tank properly you should return your hermit crabs or rehome them, they will not thrive without a properly set upRead More →

Tagged: , , , , , , , ,

Hermit crabs typically go about their molting business below ground away from your prying eyes and nosey tank mates but this isn’t always the case. Sometimes you will find yourself with a surface molter on your hands. Surface molts can be very cool for you but additionally stressful for the crab. Let’s look at the best way to handle a surface molter. First do not touch or move the crab! (unless you feel you must to ensure it’s safety) Second find a way to securely isolate the crab. It is extremely important that your tank temperature and humidity are in the proper ranges at thisRead More →
