Hermit crabs (also known as hermit crabs) are beautiful pets. Although not cuddly like a puppy, entering the exciting world of hermit crabs, the children will learn how to care for a living creature. This article will help you know more about this hermit crab’s living conditions and care. Let read through some useful tips on hermit crab tank setup.

Hermit Crab Tank Setup

Some Useful Tips On Hermit Crab Tank Setup 1

Picking the Tank

The ideal environment for hermit crabs to live in is a glass or plastic tank. When raised in this environment, it will increase and be healthy. It would help if you chose a 10-gallon aquarium with a lid.

In the aquarium, there is a sliding glass door. And its effect is to prevent moisture from inside to the outside. Tiny plastic houses with accessories like hermit crab breeding kits aren’t enough, but small plastic cages make great temporary homes or isolation tanks.

Hermit crabs, despite their name, are very friendly and very easy to live with and maintain in groups to feed.

The Substrate

One of the characteristic behaviors of hermit crabs is burrowing. Therefore, an ideal house for it will have a sandy base rather than other media types. Sand playground, have you at the home improvement store. Their advantage is that they work well and are affordable. But you will also have another alternative: aquarium sand, which is also very suitable for hermit crabs.

To use sand for crabs, you need to clean them by washing and drying them. One particular thing that you may not know is that you also have to bake the sand (at 300 degrees F) to let the moisture in the sand escape. It can then be cleaned and reused. Sand made from calcium is beautiful and comes in many different colors, but they are expensive.

Maintain Proper Temperature

Other alternatives include significantly reducing the overall fiber coating, such as Forest Fiber Bedding, including coir. We have milled the yarn to be very fine and free of dirt, making it a perfect product for the gliding process.

Cracked coral is a great alternative; however, you may want to reserve an area with Forest Carpet or sand for molting as your reclusive crabs may enjoy these substrates more. The use of gravel or wood chips should be avoided.


Hermit crabs thrive in temperatures between 72 and 80 degrees F (22 to 27 degrees C). Crabs will grow weak, stressed, and debilitated if temperatures continuously drop below 72 degrees F.

Unless you live in a tropical area, you’ll need to use a heater for at least a while to keep your crab tank at the right temperature. To keep the temperature operating, a heater (UTH), lights, or a combination of both can be available.

UTHs can be placed underneath one end of the tank to create a warm and cool side. These will raise the temperature several degrees above room temperature. They can be with thermostats to maintain a uniform temperature, which they can then set on and off timers to maintain the temperature. Purchase a thermometer suitable for the inside of the tank and regularly check the temperature near the substrate.

If the heater is not heating the tank appropriately, consider removing part of the substrate above the heater — the thinner the substrate, the more heat in the tank.

If the tank is too hot, you may want to consider raising the depth of the substrate.

In case the heater doesn’t heat the tank enough, consider dropping part of the base on top of the heater – the thinner the substrate, the more heat in the tank.

If the tank is too hot, you can increase the depth of the substrate. Some testing may have to be done for a suitable, stable temperature. Make sure the tank has a temperature gradient so the crabs can choose the temperature.

Different types of lights can also provide heat to the tank; Several lighting tests may be aimed at determining the ideal combination of lights and UTH for your tank.


In the past, it was believed that hermits were nocturnal and that providing light might not be necessary and would also annoy the crabs.

On the other hand, the low wattage and special nighttime bulbs are an excellent addition, and many crab owners have proven that when adding artificial light to their tanks, their crabs are more active and even more active near the light.

Make sure to include a light-dark cycle, such as midnight followed by midnight. This implies that daylight or fluorescent lights should only be turned off at night, while unique night lights can be used if desired.

Using a high wattage table lamp or reptile bulb to heat the tank can cause the tank to overheat and dry out, so they are not recommended. If the hood becomes too hot, wooden slats can be used to stretch it over the glass. Some range hoods include the third socket for fluorescent bulbs, and owners have reported good performance with Reptisun 2.0 lamps.

Reptile heat shields work well on glass top tanks or screens, while guards make it challenging to manage humidity as the lights get pretty hot and melt the plastic. A combination of lighting and underground heat can be available to heat the tank.

Humidity levels

Hermit crabs require sufficient humidity in their tank, combined with the right temperature. Because crabs “breathe” through their gills, their proper oxygen exchange depends on air humidity. The crab will suffocate if the air in the tank is too dry. They require a relative humidity of 70 to 80 percent.

Since humidity is so essential to crabs, you should invest in a hygrometer, also known as a hygrometer, which you can buy in the reptile section of your pet store. Excessive humidity is also undesirable as it causes condensation and promotes the growth of bacteria and fungi in the tank.

As long as the tank has solid sides and a solid top, the dish of water you put in the tank will most likely be enough to create the correct humidity. If you need to increase humidity, place a giant natural sponge in a dish of water (remember always to use dechlorinated water). Sponges can hold a lot of water and have plenty of surface area for steam to escape, helping to increase moisture.

Keep a couple of sponges on hand to swap out and clean as needed (soak them in boiling dechlorinated water or a sea salt/water combination, then let them dry completely as they are the perfect medium for washing. bacterial growth).

If the mesh or lid has vents to help manage and determine humidity, use plastic wrap or simple packing tape to control humidity.

Cage FurnishingsSome Useful Tips On Hermit Crab Tank Setup 3

To supply the cage, three items are required: a climbing material, a water bowl, and a feeding plate.


Terrestrial hermit crabs love to climb, and it is also a way for them to exercise their strength significantly. Choya (or cholla) wood is helpful because it can be engineered to be climbable.

Artificial plants are also a great addition to a crab tank. Change things around or add new objects regularly to create variety and excitement for the crabs. Some creative and inventive people even use Legos to build their crab perches.


Hermit crabs need both fresh water and saltwater, so that you will need two dishes of water. They should be large and deep enough to soak up crabs (especially oceanic plates), but also simple to get out of and not so deep that they can easily drown.

Although most species do not require this depth, you need to provide strawberry crabs with a salt tank deep enough for them to be completely submerged in. Smooth river rocks or pieces of coral can be used as ramps or steps for crabs to emerge from the water in deeper dishes.

All water given to crabs in seclusion or aquariums needs to be dechlorinated (water available at pet stores). Saltwater should be prepared with marine aquarium salt, such as dissolved seawater (blended as for saltwater tanks), rather than freshwater tank salt and never table salt.


You’ll want shallow, sturdy, and easy-to-wash dishes for your food. A flat, heavy plastic dish shaped like a rock can be obtained from the reptile area, or a shallow ceramic dish designed for small animals can be used. Some individuals also use natural sea shells for foraging.
