Do Hermit Crabs Need a Heater: Hermit Crabs and Their Heat Requirement

Hermit crabs do not necessarily need a heater, but they can also help maintain their warm climate in the colder winter months. Hermit crabs are amphibians that live in warm climates, which is why they require warm temperatures to survive. 

The temperature should be comfortable for the crab. If it’s too cold or too hot, your crab may not be able to survive. However, if necessary, you may still provide supplemental heat – an inexpensive electric heating pad works great!

How Warm Do Hermit Crabs Need to Be?

Hermit crabs need a temperature of 75 to 85 degrees Fahrenheit during the day and 65 to 75 degrees Fahrenheit during the night to feel comfortable. So, keep your hermit crab happy by heating the area around it and keeping it warm!

Heater for Hermit Crabs

Aside from the heater, the mat is also an excellent option for those with larger tanks as it doesn’t require wiring. So, you can place it anywhere in your home without disruption or damage. Finally, the heat mat can also be a lifesaver for hermit crabs in the event of a power outage.

Heating Lamp for Hermit Crabs

It can be hard to tell if your hermit crab needs a heating lamp, as they are often inactive during the colder months. However, if you notice that they are not moving around as much as usual, it may be time for them to get a warm lamp. Heating lamps come in different shapes and sizes, so it’s essential to find one that best fits the space your crab lives in. Keep an eye on your hermit crab’s temperature levels and adjust their heating lamp as needed.

Benefits of Keeping Hermit Crabs Warm

Keeping your Hermit Crabs warm will make it much easier to move the crabs around, but it will also help to keep them healthy and active during the colder months. Additionally, keeping their body temperature regulated will ensure they don’t get sick or experience health problems.

Alternatives to Keep Your Hermit Crabs Warm

Put Your Crab to a Warm Spot

Move it to a warm spot on your home’s ground level to provide your crab warmth. Ensure the lid on the container is kept so that the heat slowly warms up the environment inside the bin for your crab.

Add More Substrates to the Tank

Adding substrate to a tank can help them warm up. Make sure the substrate is moist before adding it, and ensure the crab has easy access to it – wet rocks work great! You can put a heating pad on the bottom of the tank or set the tank up in a warmer part of your house. Live plants will also help keep them warm, and you can add small light fixtures to their tank at night for added illumination. If your hermit crab is not doing well, it may be due to a lack of substrate. In this case, consider using an electronic food warmer to make life easier for your pet.

Use Towels to Insulate Tank

To do this, cover the top of the hermit crab’s tank with towels or blankets to create an insulation layer. This will help keep the hermit crab warm and the temperature consistent year-round. You can also check the thermostat regularly to maintain the tank temperature.

Make the Habitat More Humid

Hermit crabs may live in warm climates, but they still need a little humidity in their habitat to keep them comfortable. Adding wet sponges or moss balls to the tank for hermit crabs who live in warm climates can help keep the enclosure humid. Additionally, misting the enclosure every few hours can help increase moisture levels. Installing a humidity wand can be a great option if you’re looking for a more permanent solution. You can set up this device to mist the enclosure regularly, keeping the crabs comfortable and healthy.

Run a Humidifier

A humidifier is a great way to add humidity and comfort to your hermit crabs’ habitat. You can even buy a hermit crab habitat that attaches to the side of your aquarium, making it easier for you to keep an eye on them. Make sure you clean the humidifier regularly as build-up and fungus can be dangerous for your hermit crabs. 

If you can’t keep your humidifier running constantly or if it’s not enough for your hermit crab, you can try a few other options. Some people put wet moss or sponges inside their shells daily to increase humidity. You can also run a humidifier, provide them with a warm environment where they can stick their heads out of the water to warm up their bodies (basking), and place them in an aquarium with fake water or frozen peas/cereal pellets. Humidity is vital for hermit crabs – without it, they will get sick and die.

Don’t Use Heating Rocks

Many think that hermit crabs need heating rocks to stay warm. However, this is not the case. Using heating rocks can be harmful to hermit crabs. Instead, use a heating pad or warmer water tank to keep them warm and safe. Make sure to clean the heating rocks regularly, so they don’t build mold or bacteria. 

And lastly, heating rocks are not necessary for hermit crabs and can harm them. So, what’s the verdict? Heating rocks is unnecessary for hermit crabs and can be harmful to them. If you decide to use a heating rock, place it in an area where the crab cannot reach it!

Never Overheat Your Crabs

Hermit crabs are tropical creatures, and they’re very susceptible to heat-related health problems. Ensure you never heat your crabs’ tank above the recommended temperature range and that you provide them with a safe place to retreat if it gets too hot. Also, ensure you don’t leave them unattended for long periods when their tank is heated – they may get stressed out and die from overheating.

Providing Enough Room for Hermit Crabs to Insulate Them

When it comes to hermit crabs, providing them with enough space is necessary to allow them to move and heat their home correctly. Hermit crabs need at least 1 foot of space per crab and a tank size of at least 5 gallons for each pair. 

If you live in a climate where winter days can be pretty cold, consider installing a small heater in the tank to keep the crabs warm. Additionally, please provide them with artificial seaweed as they like to eat algae high in calcium.
