Vegetables You Must Avoid Feeding Your Hermits

There are a few vegetables that you must avoid feeding your hermits. If they eat any of these, it can cause them to have complications or even die.


You must avoid onions because they can cause respiratory problems or death. Onions are part of the allium family and they contain sulfur that is toxic for hermit crabs.


Tomatoes are part of the nightshade family and they contain alkaloids that can be fatal to hermit crabs.

Also, read: Why tomatoes are not safe for hermits? Know the reasons!


Avoid garlic because it contains a toxin called N-propyl disulfide, which will kill your hermits quickly if eaten in quantities.


Chives contain the same toxins as garlic and onions so you must avoid feeding this to your crabs too! 


Potatoes are also in the nightshade family and are toxic to them. If you notice your hermit crab has eaten some, it’s important to get them medical attention immediately. 


Avocado is very bad for hermit crabs because it contains persin, which will cause them to have diarrhoea and eventually die. 

Dried Beans 

Beans contain hemagglutinins that can cause intestinal problems in your hermits so you must stay away from feeding them beans.


Cabbage is also high in goitrogens, which will cause your hermit crabs to get what’s called ‘goitre’. This means their thyroid gland becomes enlarged and it can lead to hypothyroidism.

Hermit crabs need a balanced diet of protein, carbohydrates, and fat.

Vegetables are an excellent source of fibre which is what hermits require to maintain their digestion process. I

How often you should feed your pet hermit crab vegetables depends on several factors.

Including what kind of veggies they can eat, what kind they have at home, etc. 

You can feed vegetables to your pet hermit crabs daily or every other day.

However, if you notice that they are not eating all of what you give them within a couple of hours.

After offering the food, remove it from their enclosure and do not offer it again until the next feeding time.

How Long Can Hermit Crabs Go Without Food?

A hermit crab can survive up to 30 days without any source of nutrition whatsoever!

Of course, if it is not fed during this period the health and well-being of your pet may suffer greatly. 

For example, during the whole 30 days, your hermit crab might not be able to moult successfully, which results in a much weaker and fragile creature.

How Long Can Hermit Crabs Go Without Water?

Hermit crabs are not amphibians, they cannot survive on land for too long.

They need to keep their gills moist to breathe and if you allow them to dry out, their chances of survival drop significantly.

If a crab gets stuck outside during the daytime when it’s hot and sunny, it won’t have much time to find moisture before it’s too late.

The inside of a terrarium should be kept moist and humid for crabs’ survival.

They can go without food longer than water because their stomachs are airtight and will not dry out like the gills do when exposed to heat or light for extended periods.

Water dishes should be refilled daily (or even twice a day if it’s really hot and humid or there is no air movement) to keep the humidity level up in their living space.

A moisture meter can also help you monitor how moist your tank is throughout the day and what needs to be done to maintain optimal humidity levels for your crabs.
