Hermit Crab Container Syndrome Facts

Are you considering keeping a hermit crab as a pet? Or are your hermit crab pets happy, healthy and growing too big for their current tank or enclosure?

It’s essential to understand the potential risks of “hermit crab container syndrome”, also known as “hermit crab tank syndrome,” a phenomenon where hermit crabs, like other pets, only grow as big as the environment they live in and that stunted growth develops into potentially serious health issues.

What is Hermit Crab Container Syndrome?

Hermit crab container syndrome refers to the negative effects of keeping hermit crabs in an enclosure that is too small or otherwise inadequate for their needs.

While the term “tank syndrome” is more commonly used to describe poor water quality in aquariums, it also applies to the negative effects of a cramped living environment on the health and well-being of hermit crabs pets.

Hermit crab container (tank) syndrome can lead to:

  • stunted growth or developmental abnormalities
  • bullying or aggressive behavior towards others
  • poor molting, surface molting
  • stress as indicated by loss of appetite, lethargy
  • and even death in severe cases

Cramped living conditions can prevent hermit crabs from thriving and cause them to suffer from a range of health problems.

How to Prevent Container Syndrome?

To prevent hermit crab container syndrome, consider the following:

  • Enclosure Size: Choose an enclosure that is large enough for your hermit crab to move around, and have access to both land and water. The general rule of thumb is to provide a minimum of 10 gallons of space per hermit crab.

  • Substrate: Use an appropriate substrate depth for your hermit crabs. For very small hermit crabs (one inch shell or smaller), substrate should be a minimum of four inches. The larger the shell, the deeper the substrate needs to be. For hermit crabs that are older and larger, usually wearing a shell of approximately 3-4 inches in diameter, they most often require a minimum of 6″ deep of substrate (however, other factors like how many hermit crabs, size of enclosure and surface space of substrate also plays a role in determining depth of substrate needed). See more on Hermit Crab Sand and Substrate Tips here.

  • Climbing Structures: Hermit crabs need to climb, most especially Caribbean Hermit Crabs (a.k.a Purple Pincher and  Tree Crab). The hermit crab container/enclosure needs to be tall enough to provide climbing structures like driftwood or sturdy artificial plants. Not sure which type of hermit crabs you have? Here’s my blog post on Types of Hermit Crab Pets, here.

    Here are some ideas and tips on providing climbing and landscaping in your hermit crab habitat here.
  • What is the Minimum Tank Size for Hermit Crabs?

    The minimum tank size for hermit crabs depends on the size and number of crabs you plan to keep. As a general rule of thumb, a single hermit crab should be kept in an enclosure that is no smaller than 10 gallons in size, but this refers to very small young hermit crabs.

    Larger enclosures are always better, as they provide more space for your hermit crabs to move around and explore. As well, hermit crabs grow fairly quickly and they will outgrow anything smaller than a 10 gallon tank within a year or so, even starting out as a very small young hermit crab.

    For multiple hermit crabs, you’ll need to provide at least 10 gallons of space, plus a minimum 5 gallons of space for each additional crab. 

    It’s important to keep in mind that hermit crabs are social creatures and thrive in groups, so it’s best to keep them in pairs or small groups whenever possible. 

    One young hermit crab is never a good idea, it will become lethargic and possibly stop eating over time.

    FAQ:

    Q: Can hermit crabs live in a plastic container?
    A: While hermit crabs can live in plastic containers, it’s important to ensure that the container is appropriately sized and has proper ventilation.

    Q: How often should I clean my hermit crab’s enclosure?
    A: It’s essential to clean your hermit crab’s enclosure regularly, including removing any uneaten food and waste, and changing the substrate every few months.

    Q: Do hermit crabs need a water dish?
    A: Yes, hermit crabs require a water dish to soak and regulate their body moisture levels, one for fresh water and one for sea water (saltwater 

    Summary:

    Hermit crab container syndrome is a real risk for pet hermit crabs, but it can be easily prevented by providing a suitable environment that mimics their natural habitat. Choose an appropriate enclosure size, provide climbing structures and hiding places, and maintain the appropriate temperature and humidity levels. By taking these steps, you can ensure your hermit crab stays healthy and happy.

    Thinking about going BIG? 

    If you have hermit crabs that are over 5 years old and continuing to get bigger… it’s inevitable to think about going bigger! Give them a bigger enclosure so they can do even more climbing and exploring and continue growing!

    Reptile terrariums and enclosures at the pet store can be great. Also, large aquariums work well. But they are hundreds of dollars!

    If you’re a little creative, crafty and patient, consider going even bigger and doing an Ikea Detolf Hermit Crab Habitat HACK!

    Look for a glass display case or cabinet. Yard sales are a great place to find these, or check out Ikea! 

    This is an Ikea Detolf glass dispaly case that’s been converted into a hermit crab habitat. It’s over 5 feet tall, took a couple of months to finish and the hermit crabs LOVE it!! And the best part?  It’s only $79 at Ikea and takes NO SKILL or BIG TOOLS to convert it!

    You can’t beat the space when comparing to pet store terrariums much much much smaller. 

    Ikea Mislbo Hermit Crab Habitat Hack for hermitcrabpets

    Thinking about going EVEN BIGGER? 

    This is an Ikea Milsbo glass display case that’s been converted into a hermit crab habitat. It’s big and tall, took a couple of months to finish and the hermit crabs LOVE it!!

    This hermit crab habitat hack was more expensive, took a little longer and we used a drill. (compared to the Ikea Detolf hack above, no drill needed). 

    Why did we need a drill? Because the top and bottom is metal, we decided to drill holes to add lighting and airline tubing so we could add a water filter and airstones to the water bowls. Not necessary, BUT also not hard at all!
