by Stacy Griffith Contributor Stacey May – My Hungry Hermit Why should I use a thermostat with my heat mat? Hermit crabs need a consistent temperature range of 75-85°F (24-29.4°C) in their habitat (crabitat). A reptile heat mat provides gentle warmth, while a thermostat with a probe prevents overheating by regulating the output of the heat mat. Step-by-Step Guide to Setting Up a Heat Mat with a Thermostat 1. Choosing the Right Heat Mat 🔥 Recommended Heat Mat: Ultratherm at Bean Farm If you have issues finding an Ultratherm, I recommend this heat mat: Kabasi’s Heat Mat for Reptiles (Amazon) 2.

Welcome to Hermit Crab Pool Boy Training 101!  We hope the following information will cover hermit crab water pools from a-z. If we didn’t cover something here please feel free to comment or contact us. Let’s dive right in, the water is fine! Your tank should have two types of water bowls or pools: ocean water made from marine-grade salt and freshwater. Tap water contains beneficial minerals and metals so we discourage the use of distilled or otherwise purified water. Tap water must be treated with a product like Seachem Prime to make it safe for use. Prime also binds ammonia. In our testing, ammoniaRead More →

Land Hermit Crab Shell Guide 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 shellRead More →

Land hermit crabs breathe through a modified gill. It is important to protect the gills from strong fragrances, essential oils, candles, household cleaners, chemicals, smoke insecticides and other airborne irritants. Be mindful of what you spray or use near the crabitat even if your tank is fully sealed. Residual product may still be in the air when you open your tank. If you are forced to have your home sprayed for insects ensure your tank is fully sealed with saran wrap or something similar. Allow the house to air out at least 24 hours before unsealing your tank.Read More →

Please note: As we do not have the necessary information to determine how land hermit crabs are affected by ammonia build up in the water and to what degree we err on the side of caution and treat our water as we would for fish. All information regarding Prime is based on the assumption it is being used in a stable fish tank. Our use is much different. Our primary reason for using Prime is to remove Chlorine and Chloramines and heavy metals from the water and Prime does that well with no recurrence that requires retreatment. Ammonia build up is only an issue whenRead 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 pet store 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 properlyRead More →

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 from it’s tank mates. It is extremely important that your tank temperature and humidity are in theRead More →

This is a (hopefully) more simplified revision of the original.  I have also created a printable calendar for tracking that is free to download. Introduction: The objective of this method is to reduce the impact of physical stress by keeping the hermit crab above ground eating well and exposed to light. Both are vital to the hermit crab’s ability to recover. This is a thirty day method. While this can be accomplished in three weeks, there is no reason to rush. If you are adding new (wild caught) hermit crabs to your existing colony it is important that you do not introduce sick or contagiousRead More →

written by Sue Latel March 8, 2006 Little Billy has had 3 hermit crabs since his 12 birthday. He has a 20 gallon tank housing his 3 small PP crabs. One day when he is at the store picking up some ocean salt water for his crabs, he spots a tank containing 2 poor little Ruggies that have no water except for a damp sponge, huge pellets of food that he doubts they have even attempted to eat, and no ground cover to protect them from the 100 watt heat lamp that is shining directly on them from an open tank top.

Originally written by Vanessa Pike-Russell Behaviour in the Wild Land hermit crabs are territorial animals, and as such they will often act aggressively towards one another to establish a ‘pecking’ order among their colony. Sometimes this can be in the form of ‘feeler’ or antennae fights, others in violent pushing or flicking fellow tank mates out of the way. Usually this is not serious enough to warrant intervention. However, some hermit crabs will act in a manner that is harmful to other hermit crabs, often trying to pull their hermie buddy out of a desired shell, or attacking eyes, antennae, claws, legs or abdomen. IfRead More →

Originally written by Vanessa Pike-Russell It is important that your land hermit crabs are able to bathe themselves. Bathing allows your hermit crab to re-hydrate their gills, replenish shell water and adjust the water salinity as well as flush out feces and wash off the sticky juices and food stuffs which are present when you offer fresh fruit, seafood and raw foods. Hermit Crabs urinate through their antennae, so any water spills during handling is shell water. Hermit Crabs have an anus located on the end of their abdomen, and have been observed to flick any wastes (droppings) out of their shells. These feces are oftenRead More →

Compilation of information by Vanessa Pike-Russell and Stacy Griffith To keep your hermit crabs healthy and happy their environment should be kept in optimum temperature and humidity levels. If you are not able to keep the environment stable then your crabs will weaken and become stressed which will lead to death. Hermit crabs are ectothermic creatures and must have a warmish and cooler side to their substrate. If your temperature falls below 75F on a frequent basis you need a reliable and safe method for heating your crabitat. Whatever type of under tank heater or other heating method you use, it is STRONGLY recommended thatRead More →

Originally written by Vanessa Pike-Russell-Updated by Stacy Griffith What is Humidity? Humidity is a measure of the amount of water vapor in the air. It can be expressed in several ways. “Specific humidity” is the mass of water vapor per unit mass of combined dry air and water vapor, generally expressed in grams per kilogram. The specific humidity of an air parcel does not change with temperature. “Absolute humidity” is the density of water vapor, expressed as grams per cubic meter of air. “Relative humidity”  is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a givenRead More →

Originally written by Vanessa Pike-Russell-Updated by Stacy Griffith There are a few reasons your hermit crab may be less active than you expected. Is your crabitat boring? One way to increase activity is to create an obstacle course within the tank, using cholla logs or driftwood, coral and/or rocks. Providing an enriching environment will encourage your hermit crabs to explore. They are curious beings and they love to climb. Land Hermit crabs are primarily, but not exclusively, nocturnal creatures. That means that in the wild they sleep during the day and are active at night. This allows them to escape the drying heat of theRead More →

Originally written by Vanessa Pike-Russell-Updated by Stacy Griffith All hermit crabs require some access to salt in their diet, no matter what species. The habitat of land hermit crab species differs from location to location, and they have adapted to the environment they live in. Approximately 3.5%, or 35 parts per thousand solution is recommended for the “Ocean Water” pool within your tank. Typically mixing according to package directions is sufficient. If you are using distilled or spring water it may have varying amounts of salt already within the water, so take that into consideration.. It is important to note which type of water youRead More →

What is Autotomy? Comes from the latin words autos for “self” and tomos for “cut Autotomy can be described as self-cutting, Websters dictionary describes autotomy as a “reflex separation of a part (as an appendage) from the body: division of the body into two or more pieces.” Hermit Crabs can autotomize (drop) and regenerate (regrow) their limbs from juvenile to adult stages. The break occurs along a fracture plane located at the appendage’s base. Why do land hermit crabs drop limbs? The rate at which the limbs regenerate depends upon the molt cycle (Morgan, 1900; Zeleny, 1908; Bliss, 1960; Skinner 1962, 1985). During aggressive encounters,Read More →

A hermit crabs shell serves two purposes: first protection of the soft abdomen and second it prevents desiccation (drying out). A hermit crab that has left the protection and life-sustaining seashell home is telling you it’s in distress. Below we expand a bit on these causes. Physical Stress Land Hermit Crabs endure a great amount of stress before reaching the pet store. The harvesting and shipping of hermit crabs is a very inhumane process and the crabs suffer because of it. They then arrive in pet stores, who in most cases, don’t know how to properly care for them. They arrived stressed out, dehydrated andRead More →
