How to Feed Your Hermit Crabs
1. Feeding Your New Crabs
The commercial crab food that you purchase must be of high quality. There is a wide variety to select. You can choose a few and alternate.
These will ensure that your crab gets the right minerals and eat a balanced diet.
B). Fruits and Vegetables
Since they enjoy choosing a variety, give them different fruits and vegetables each day.
Don’t first cook the vegetables. First rinse the vegetables’ in clean water, before giving the crabs.
Remember that fruits and vegetables are not a substitute for commercial crab foods. They are just a supplement treat.
Hermit crabs get a lot of nutrients from the industrial food crabs. Since they eat little in a slow way, give them once per day.
Just as the wild crabs enjoy eating wood, it’s not different from your crab. Ensure that the crab habitat has a piece of wood.
Apart from eating, they also play with it. Remove it once it becomes slimy or old. Unlike fruits, woods last longer and are readily available.
If you want your crab to grow stronger, don’t assume proteins in their foods.
Some of the benefits of protein to crabs include; helps in maintaining crabs musculature and exoskeleton. They also require protein to process carbohydrates.
You can get proteins from seafood, animal proteins, grubs or worms after the rain.
You can alternate the protein every day when feeding your crabs.
Note: When giving your crabs animal proteins, first remove the bones.
Just like humans, you can give your crab a gift. Though your crab enjoys eating fruits and vegetables, some natural peanut butter is good.
You can also treat them with some honey or trail mix. Washed grass and popcorns are also lovely alternative treats.
f). Calcium supplements
Apart from proteins, your crab also requires calcium supplements. These will ensure that it retains a healthy body, proper shell maintenance, and a good exoskeleton development.
Food like a crushed oyster shell and Cuttlebones is rich in calcium. Calcium sand substrate is also a great substitute.
g). Feeding them at night
Crabs are nocturnal. They like feeding in the evening or during the night. During the day, they enjoy hiding or burrowing inside the sand.
If you feed the crabs with meat food or seafood, remove it in the morning. Some pests and flies get attracted to these foods.
f). Use shallow dishes
When deciding on the bowl to use when feeding your crabs, ensure it is superficial.
If you use a taller bowl, you will starve your crabs. It might be impossible to access food.
The dish should be plastic and non-porous. They have a high sensitivity in metallic bowls. Germs and bacteria’s thrive well in a porous material.
2. You Need To Control the Environment Of Your Crab
You have to give your crab some water. They will play with it, drink and take a bath. If you are using tap water, use a de-chlorinator.
If the water has chlorine and chloramines, it will affect the gills of your crab. To protect your crab from suffocating, provide both fresh and saltwater. It helps the gills of your crabs to stay wet.
b). Control the level of humidity
To enable your crab breath well, ensure there is a high humid. They are likely to suffocate if the level goes low. It should be around 75%.
A natural sponge can help you. You need to put it inside the water dish. It should be in the enclosure to be able to disperse the moisture.
c). Ensure that your compound is clean
You need to clean the crab tank regularly. These will help to avoid any form of contamination.
Once you clean, replace the woods and the substrate. Twice or thrice in a year, remove all the water and wash the tank clean. Wash the water dishes and food bowl regularly.
When cleaning it, avoid cleaning chemicals. If you accidentally put insect spray or wood polish in the food or water, the crab will die. Room deodorants and fresheners are also very poisonous to the crabs.
When playing with the crabs, avoid putting them on the carpet. In most cases, when washing carpets, people use chemicals.
Those chemicals are very harmful to your crab. If you have to put it down, put it on the lino floor or the floor with tiles.
