What To Look For In Lights For Hermit Crabs?
Hermit crabs are nocturnal animals, so they are going to be the most active at night. This means that your hermit crab will likely spend most of the day hiding, whether in its shell or in a hideaway in its cage. The brighter your hermit crab cage is, the less likely your hermit crab is to be active. This being said, there are ways you can illuminate your hermit crab tank at night to view its activity without having a negative impact on your crab.
Here are some important things to look for in hermit crab lights:
- Day vs night. Regular white light or full-spectrum lighting can be used during the day for your hermit crab, but red light is recommended for night, so it won’t affect your crab’s activity.
- Heat output. Your hermit crab tank should be kept at a daytime temperature between 70°F and 75°F, so if you don’t live in a very warm climate you may need a light that produces some heat.
- Made for reptiles. When purchasing equipment for your hermit crab, it is important to choose products made specifically for reptiles so they will be appropriate for your pet.
- Automatic timer. Though hermit crabs are nocturnal and will be most active at night, they still require a 12-hour day/night cycle. To make sure the day/night cycle remains consistent, consider hooking up your lights to an automatic timer.

Tips For Heating And Lighting Your Hermit Crab Tank
Hermit crabs are native to tropical areas where it is always warm, so you should plan on keeping your hermit crab tank heated to a temperature between 70°F and 75°F. It is also important to maintain humidity in your hermit crab habitat, so you’ll need to utilize a combination of heating and lighting elements in your tank if you want to create the ideal habitat for your pet.
Here are some simple tips for heating and lighting a hermit crab tank:
- Choose a tank or terrarium that will retain heat and humidity – an all-glass or acrylic tank is preferable to a plastic or screened-in enclosure.
- Use a full-spectrum or white light bulb for 12 hours during the day – if the room you keep your crab in gets plenty of natural daylight, this may not be necessary.
- Install a red-light bulb for nighttime illumination, keeping it on for 12 hours overnight.
- If the ambient temperature in your home is less than 70°F during the day, you may want to install an under-tank heater to keep the tank warm.
- Install your under-tank heater along one of the side walls of the cage instead of under the substrate – hermit crabs burrow and may hurt themselves if they dig into the heating element.
Now that you have a better understanding of your hermit crab’s housing requirements, you’re ready to start shopping for equipment. Take what you’ve learned here to decide what combination of heating and lighting elements is best for your hermit crab.
Though hermit crabs are not one of the most difficult pets to keep, they have much different requirements than a cat or dog. In addition to keeping your hermit crab habitat warm and humid, you also need to recreate the 12-hour day/night cycle so your hermit crab can exhibit natural behaviors.
