You can set up a hermit crab crabitat easily if you have food, water (freshwater and saltwater), extra shells, substrates, and hideaways. Plus, you need to maintain property humidity and temperature (heat) level in the crabitat. Also, use a big tank and with every essential accessory in it to keep the hermies happy and healthy.
Do you know hermit crabs are the most delicate crab species in terms of taking care of them? So, let’s follow the footsteps of this guide and create a cozy haven where your hermit crabs can flourish and explore to their heart’s content.
Let’s dig in!
Items Needed to Set Up a Hermit Crab Tank
1.Tank
Choose a glass or plastic aquarium, minimum 10 gallons in size. Larger tanks help maintain stable conditions and provide ample space for exploration.
2.Substrate
Use a blend of sand and coconut fiber substrate in a 5:1 ratio, at least 6 inches deep to allow for burrowing and molting.
3.Heating Source
Use an under-tank heater or heat lamp to maintain a temperature range of 75°F to 85°F.
4.Thermometer and Hygrometer
Monitor temperature and humidity levels between 70% and 80%.
5.Water Dishes
Provide two shallow dishes for fresh dechlorinated water and salt water for drinking, bathing, and hydration.
6.Hiding Places
Include coconut huts, caves, or other suitable hiding spots to reduce stress and provide security.
7.Climbing Structures
Use driftwood, cholla wood, and climbing vines to keep crabs active and mimic their natural environment.
8.Feeding Dish
Provide a shallow dish for food, ensuring it’s easy to clean and large enough for a variety of foods.
9.Shells
Offer extra shells in different sizes for molting, as crabs change shells as they grow.
10.Decorations
Use safe plants, coral pieces, and shells, avoiding any sharp or toxic items.
11.Lid
Ensure a secure, well-ventilated lid to prevent escapes and maintain humidity.
12.Spray Bottle
Mist the tank regularly to maintain humidity, keeping the substrate damp for burrowing.
13.Dechlorinator
Use dechlorinator to treat tap water, removing harmful chlorine and chloramines.
14.Saltwater Conditioner
Create saltwater using a marine salt mix, crucial for crabs’ osmoregulation and health.
15.Cleaning Supplies
Use non-toxic cleaning supplies to maintain tank hygiene, preventing harmful bacteria buildup.
Tank Size and Recommende
| Tank Size (Gallons) | Recommended Number of Hermit Crabs | Proper Space (Square Inches per Crab) |
| 10 | 2-3 | 48-72 |
| 20 | 4-6 | 32-48 |
| 30 | 7-9 | 32-43 |
Important Note:
Fill the saltwater bowl with a blend of dechlorinated water and aquarium salt mix. Remember, don’t mix table salt into the water. Otherwise, it could be harmful for your hermies!
Pick a Peaceful Spot for Placing the Tank!
Selecting the perfect spot for your tank is one of the main steps that if you focus on everything but ignore it then your all efforts will go in vain.
I’m going to introduce a few useful tips that will help you pick a perfect place for keeping the hermit crab tank. Let’s walk through each one of the healthy tip:
1.Keep it Away from Vents:
Make sure the tank isn’t near any air vents. It’s important to keep the tank at a stable temperature.
If it is close to a vent, the crabs could be harmed by sudden blasts of cold air. And you should know that cold temperature and air is the enemy of hermit crabs.
2.Avoid Direct Sunlight:
You should avoid placing the tank in direct sunlight. Whether it’s near a window or somewhere outside, don’t place the hermit crab tank into that place where there is direct sunlight exposure. Crabs are not fans of sunlight, and it can dangerously heat up the tank.
3.Pick a Moderately Busy Place:
You should choose a spot that’s moderately busy, but not overly crowded. Understand it – “Place your crabs somewhere you’ll frequently pass by, so you can easily check on them.”
However, try to avoid placing the tank in areas where you use potentially harmful sprays, such as hair spray, cologne, or room deodorants.
So, many hermit crab keepers have shared their experience that they skip their bedrooms for them. Their hustle and bustle in the night was quite noisy. That’s why I recommend you to keep the crab shindig away from your sleep zone!
