You can also learn about Heat lamps, Isolation tanks, and Misting bottles. If you have any questions, leave a comment below! Also, don’t forget to read the article about Heat lamps! Here’s a brief description of each.

Isolation tanks

There are a few things you should do before introducing a new hermit crab to your existing crab tank. You should clean the entire tank and rinse out any leftovers. A new hermie may have some scent, which will help acclimate them to one another. If you are going to introduce a new hermie to an existing tank, make sure you give it a salt bath before moving it into the main tank.

If you do not want to clean the tank, you can use nonchlorinated saltwater solution. Saltwater mixes are available at pet stores. Make sure to submerge your crab and add a few pebbles or sponges as a pathway out. You can also bathe the new hermit crab to remove any scents or other impurities that may affect it. While cleaning the tank, do not immerse it for too long. Crabs live on land and need air to breathe.

After your new hermit crab has settled into his new home, you should introduce him to other hermit crabs in the same tank. This is the best way to avoid the stress of an unknown hermit crab. If the new crab is molting, you should separate them and ensure that they do not get too close to each other. You can also use a small aquarium in the main tank, which will provide the same humidity and temperature for the crab.

Misting bottles

Using misting bottles to introduce a new hermit to its home can make the transition easier. These creatures are often timid and can be easily intimidated by human contact. However, it is important to use warm water as a softener. It will also help to relive the initial stress associated with hermit crab ownership. Lastly, make sure the water contains no chlorine or chloramine. Some chloramine removal products may leave traces of toxic ammonia in the water.

Hermit crabs prefer a moist environment, so you need to keep the humidity level around seventy percent. The ideal humidity level for hermit crabs is between seventy and eighty percent. Using a fluorescent bulb to provide light will also help maintain humidity levels. The bulb should be placed inside the terrarium or habitat hood. This light should be used eight to twelve hours a day. Do not expose the hermit crabs to UVB lighting.

Hermit crabs also need high humidity, and misting your habitat will make that environment more humid for them. The humidity level in their habitat will increase their activity levels. You can also provide their habitat with toys and shells. If you want to get more creative, you can add some shells to their habitat, as they are known to like them. To ensure that your new hermit crab has a happy and healthy life, you can buy shells from a local pet store.


The first step to hand-feeding a new hermit crab is to let Hermie wander across your palm. Remember that he is a crab with compound eyes and will clamp down when it feels something that touches his open claws. You can gradually increase the amount of time you spend hand-feeding a new hermit crab as it gets accustomed to the routine. Eventually, Hermie will come around to the idea of hand-feeding you.

The new crab will likely be territorial for the first few days, and will probably want to assert its dominance. Remember that this behavior is natural since it challenges the existing hierarchy. You should expect leg sparring matches and antennae wars, which are entirely normal. Hermit crabs are social animals, and once they have established the pecking order, they’ll get along fine. As long as you’re careful not to frighten them too much, they will get used to each other and settle down in time.

Feeding a new hermit crab requires two claws, one for holding the food and one for tearing and bringing it to the mouth. If your new hermit crab is missing a claw, you can still feed him by using a soft food. You can also mix calcium-rich foods with other food, such as crushed oyster shells. If you don’t want to use food, you can feed your hermit crab dry food.

Heat lamps

One way to warm up your hermit crab’s tank is by using heat lamps. You should use a low-wattage lamp with humidity-retaining substrate, such as sphagnum moss. Position your heat lamps near your crab’s water bowls and switch them off at night to avoid disturbing their circadian rhythm. If you have a larger tank, you can also try a UTH, which helps regulate the temperature of the tank.

Hermit crabs need a warm damp habitat. The ideal temperature for the tank should be about 75 degrees Fahrenheit, with a relative humidity of around 75 percent. To monitor the temperature, use a thermometer and hygrometer to keep the temperature within the appropriate range. You can also keep damp sponges in the tank to maintain a consistent humidity level. In cold weather, heat lamps can be used in combination with a humidifier.

If you do not want to purchase a heat lamp, you can also use a basking spot bulb for your hermit crab. These bulbs produce both light and heat and are designed to be warmer than general daylight bulbs. For a 20-40 gallon tank, 50 watts may be sufficient. Lastly, you can buy a basking spot bulb with a dome and fixture for your new hermit crab.

Full spectrum lights

If you want to bring your hermit crab into the light, you can start with a night-only bulb. You can use a standard incandescent bulb to start, but that won’t provide UVB. You can use a special UVB fixture if you want your crab to get the benefits of UVB as well as light. These lights are important to your crab’s health in many ways, including increasing their activity.

Another way to introduce full-spectrum lighting to your hermit crab is to use daylight-like LED bulbs. These mimic natural light, but they produce a lower amount of color brightness. This is especially important if your crab spends a lot of time at night. You can also use infrared bulbs or CHE bulbs, but keep in mind that they can also heat your hermit crabitat.

Full-spectrum lights are best for hermit crabs that live in a temperature warmer than 21 degrees Celsius. They need an outside heat source. A heat lamp can be a good option, but you may also want to use a heat lamp near the water bowls. This way, your hermit crab will have the same type of light as it needs. But you should remember to replace the UVB bulb after six to twelve months. Aside from the heat generated by the bulb, you should also be careful not to use heating pads, as they can burn your hermit crab or create air pockets.

Shell ripping

One of the most frustrating problems to deal with when introducing a new hermit crab is shell ripping. Crabs are naturally afraid of their shells, but you can avoid this problem by following these simple guidelines. First, make sure you provide your crab with a clean, sterile habitat. This way, it will be easier for you to get your new pet used to your home.

Second, if you are introducing a new hermit crab into the tank, you should be aware that this behavior is common. Some new owners mistake the shed exoskeleton for the body of their newly introduced hermit crab. In some cases, this is unintentional, and the hermit crab simply wanted to rest in its shell. Before the molt, she will isolate herself from her tank mates and bury her body in the sand.

Fortunately, this behavior is not that common. Hermit crabs normally behave the same way with each other. They engage in feeler fights and ’pushing contests’. The first one is a way of getting acquainted with each other by sniffing each other. The second one is an attempt to make your new crab feel safe. The first hermit crab will also wildly wave her antennae and flick its legs and claws. When they meet, the crab won’t understand how to go around, so the ’code talk’ process begins.
