A natural approach to hermit crab care.

From My Experience

A lot of crab websites attempt to cover all of the bases of crab care.  Well, my interests are centered around nutrition and therefore food will be the focus of this site.  However, I will share with you some of my own tips that I've learned through experience.

Balance

 

Though we all joke about crabbing to be an addiction, it is important to know your limitations.  Enthusiasm for pets cannot be weighed by how many pets you have.  A person housing 30 crabs doesn’t necessarily have more interest in or affection for their crabs than the person with 2 crabs.  Never buy more pets than you can properly care for, even if it means having none.  Pets should never be regarded as a burden because their caregivers feel overwhelmed.  Much depends on your individual circumstances.

 

When I was keeping crabs in a 10-gallon tank in an office building where I worked, I often wondered how large a tank my boss would allow—aching to upgrade to house more and more crabs as my addiction grew.  I figured that my current set-up would allow for 5 small crabs without overcrowding them.  Five of them demolished the tank every night making it look unsightly each morning and someone was always in-molt for me to worry over.  I realized that maintenance of 2 crabs had been much easier to manage than 5 in a place of business.  When I changed to part-time employment, I realized that I would have leisure to enjoy the crabs in the comfort of my own home.  So, I obtained a 55-gallon tank and outfitted it nicely.  To my surprise, it housed 5 crabs rather comfortably (I had imagined it would be boring or appear empty).  I could easily justify collecting more crabs, especially since they serve Crabotanicals as guinea pigs when I am conducting food trials.  But I feel rather content with the 5 adorable crabs I already have, and if the need should arise for me to adopt or rescue some unwanted crabs, or if I find an exotic species available I’ll have room for them without having to invest in a still larger tank.

 

My advice is this:

 

If you think you want more crabs than you have, consider carefully your motive. 

Why do I want more than I already have? 

Am I obsessed?  Am I being emotional or rational?

Will I want this in a year?  In 5 years? 

 

Consider what will be involved in expanding. 

                Am I taking good care of the pets I already have?

Do I have enough time, money, and experience to take on more responsibility? 

Am I comfortable with the molting process yet? 
Do I know what to do when I see mold, mites, or aggression? 

 

Then I would say:

Give it two weeks just to make sure the urge doesn’t go away.  Even if you know your limitations, there is no sense in pushing the limit to the maximum today.  

 

Some crab keepers find themselves tempted to buy a crab or two each time they visit the pet store.  Balance for these people may mean avoiding the place altogether.  Once, when I was in the process of setting up my 55-gallon tank, I happened by a pet store with a darling, energetic crab, with a sound structure and attractive coloring.  My first impulse was to buy, buy, buy!  I reasoned, “I have a massive tank to fill up; what am I waiting for?  Grab him up!  Buy!”  But since my current crabs were cramped in their temporary 10-gallon tank, I knew the timing was not right.  But a mom approached with her daughter for the purpose of buying a crab.  I was able to help them see the benefits of purchasing this healthy crab, and I felt good about giving him a good start in a new home.   

A Wise Investment

Choosing a crab

Although it is a noble endeavor to rescue a sick or injured crab, we suggest that you only pay for healthy crabs. Giving your money for crabs theyve given inadequate care doesnt encourage the pet stores to improve their practices. It is very difficult to nurse a sick crab back to health.

We suggest that you carefully inspect the crabs you intend to purchase making certain that they have all of their limbs. Insist on handling the crabs yourself (unless you are afraid of them). Hold the crab gently in your fingers hovering slightly over your other palm. Exhale gently a few inches from the crab as if you were fogging up a window with your breath. This burst of warm moist air usually coaxes a crab partially out of his shell enough for you to get a good look at him. You may find damaged or missing antennae. Light pink or peach crabs should not be handled further because they may have recently molted and their exoskeleton may still be soft. Chipped leg tips or missing limbs are also common. Anytime the exoskeleton is compromised, then the crab may be easily be infected with bacteria and the immune system could be compromised. Damage to claws could hinder their ability to eat normally. Antennae damage could keep them from locating the food dish and sensing other things in their environment making them somewhat vulnerable. Bright-colored crabs usually indicate overall health and adequate diet, but you must take into account the difference in color between species. Try to find an active (but not panicked) crab. A crab whose exoskeleton is shiny rather than dull and who has tiny black "fingernails" at the tip of his legs may have recently molted. This is desirable (although optional) because it will allow time for the crab to adjust to the home youve setup for it and allow a rest period before it needs to molt. This is good for crab and keeper alike! In our experience, you usually have to settle for an imperfect crab, but try to get one in the best condition possible.

Dont get seduced into buying a crab for its seashell because he may abandon it at any time. That being said, you are also investing in one shell option for the tank, so you may want a crab with a shell that has no holes or rough openings.

You are welcome to shop for a crab size of your choice. Some prefer tiny crabs, others prefer jumbos. Some prefer to buy crabs of different sizes. Buying crabs of similar size makes the sharing of seashells easier but can also increase the competition for shells. Size difference is not in itself a cause for aggression, although a larger crab is always going to have superior defenses.

Sometimes it is possible to find out when the pet store receives shipments of "fresh " crabs, which can be very helpful especially when that pet stores crabitat conditions are deplorable. It is important to be respectful when dealing with pet store personnel, even when you feel outraged about their policies regarding hermit crabs. You may find opportunities to teach them about hermit crab care a little at a time and "buy" yourself favor by being respectful.

Ask about a guarantee. Some pet stores will let you return a crab if it gets sick or dies within a certain period of time. Because the most common cause of death for a new crab is pre-purchase stress, the length of this period allowed for return may be important. One pet store in our community allows 48 hours, while another allows 14 days. If you suspect the crabs have had to endure poor conditions you may not want to risk purchasing without a long return period.

Dont waste your money

You can usually find a use for anything you buy, but a lot of crab keepers have regretted these purchases:

Calci-sand is expensive and doesnt work well for the purpose for which you bought it.

All-in-one crab homes and critter carriers crab cages. Some of these include metal parts, allow too much heat and moisture to escape, and are small and cramped. Weve seen these for sale for $45 dollars (US).

Commercial food. A lot of serious crab keepers dont make it through a single bottle of commercial food before making the switch to all-natural foods.

Sponges. Sponges can be very helpful when used correctly, but many people find easier alternatives to boosting humidity and leave off using sponges altogether. Some people have spent up to $16 dollars (US) for a good quality sea sponge.

A 10-gallon tank. Usually, a 10-gallon tank can be bought new for a reasonable investment $10 (US), but there are lots of free ones to be had. It is a common garage sale item and you may have a friend, relative, or neighbor who has an old own tucked away in a closet. If youre not in a hurry, you should ask around.

Great buys

Holmes humidifier can serve the place of expensive hygrometers. Once properly calibrated, these gauges are remarkably accurate.

Suction cups. You may find 101 uses for suction cups in your crab tank. Crab keepers use them to suspend nets, secure climbing walls, fashion second levels, etc. The fact that they are reposition-able makes them versatile. They range in quality quite a bit, but a good suction cup is worth its weight in gold. Fortunately, they are usually inexpensive.

A big aquarium. Lots of crab keepers regret not investing in a large tank right away. If youre eventually going to splurge on a 75-gallon tank, you may regret having bought the 10, the 20, and 40-gallon tanks along the way.

Try before you buy

Crabbers who stabilize their tank conditions (heat and humidity) before moving in their first hermit crabs usually have more success in getting the crabs through that awkward adjustment stage. There is a lot of fine-tuning that goes on while setting up a proper crabitat and the ups and downs inherent to your learning curve can be very stressing to a crab who is already somewhat bewildered by his new surroundings. However, if you allow yourself time to get a feel for maintaining the crabitat before taking on the responsibility of a pet, you wont be devastated if your substrate dries out or your humidity takes a dive. Planning ahead affords you an opportunity to network with hermit crab forum members, wait for them to weigh in, and implement their advice at your leisure. This also demonstrates to your parents that you will take a serious interest in the welfare of your pet.

We understand that not everyone thinks this far ahead when your eyes meet theirs, it is love at first sight, and the sales person is persuasive. Inevitably, some will purchase a crab or two before thinking things through carefully. If this is true in your case, take heart! You can be successful if you work quickly learning all you can, making the proper adjustments.
