Watermelons are sweet fruits that are one of the favorite treats of hermit crabs. These fruits not only give them a change from their usual food but also provide essential nutrients such as carbohydrates, minerals, and vitamins.

Watermelons are sweet and watery fruits that can act as a refreshing snack for us, particularly during the summer months. But can these treats work just as well for your pet crabs? That’s what we aim to figure out in this article. If you have any doubts or questions about feeding these melons to your pet friends, you can find their answers below.

Is watermelon healthy for hermit crabs?

Did you know that hermit crabs are scavengers in the wild, eating anything they can come across? In captivity, they’re not all that different either; no matter what you feed them, they will most likely gobble it down.

But just because they will eat anything doesn’t mean it is healthy for them. And since they cannot think about their health, the responsibility of doing it falls on you. So, can watermelons benefit the health of your crabs? We’ll get to that in a minute, but let’s first go through the nutritional table of these fruits given below:

The nutritional value of watermelons

Vitamin A569 IU
Vitamin B1 (Thiamin)0.033 mg
Vitamin B2 (Riboflavin)0.02 mg
Vitamin B3 (Niacin)0.178 mg
Vitamin B5 (Pantothenic acid)0.221 mg

As you can see for yourself in the table, watermelons are rich in Vitamin A, and along with it comes beta-carotene, an organic pigment that is vital for keeping the crab’s shell bright and colorful.

These fruits also contain Vitamin C, which strengthens their immune health, preventing them from all kinds of infections (which are often the cause of their death in captivity). Calcium, a mineral that is most essential for their health, is also present in watermelons.

Additionally, watermelons are rich in antioxidants, carbs, and fibers, all of which are necessary for your crab’s well-being. It would, thus, be safe to assume that these fruits are great for the health of the hermit crabs.


Can watermelon be fed to hermit crabs along with its seeds?

While the inner flesh of watermelon is both healthy and delicious for the hermit crabs, what about the little black seeds present in it? Are these seeds edible to your pet friends as well? No, they aren’t.

It might come as a surprise to many, but amygdalin, the chemical that makes apple seeds lethal, is also present in the watermelon seeds, but a much smaller amount. This small amount might not mean much to you, but it can be highly toxic to the hermit crabs.


What about watermelon rind? Is it edible to hermit crabs as well?

The rind of watermelons is thick and fibrous and is too tough for us to eat, which is why we usually throw it away. Can you imagine your little pets feeding on something that tough? We know you can’t. And even if they somehow manage to cut off a piece of the rind and try to eat it, it’s just too fibrous for them.

Therefore, it is best not to serve them watermelons with the rind attached; serving them watermelon flesh separately is a much safer alternative.


Can hermit crabs eat dried watermelon?

All of us know that watermelons are seasonal fruits that are only available during a small period of time. To preserve these fruits and enjoy them outside of the season as well, watermelons are dehydrated. These dehydrated versions are referred to as “dried watermelons.”

Contrary to popular belief, the nutritional value of watermelons is more or less the same in both their fresh and dried versions, except for one significant difference. This difference is in their sugar levels. Since the process of dehydration sucks all the water out of these fruits, what’s left behind is concentrated sugar, resulting in a higher calorific count.

So, does this mean You should not feed dried watermelons to the hermit crabs? Not really. Your little pets can enjoy these dried fruits as long as you are careful about feeding it to them occasionally and in small quantities. In careful moderation, dried watermelons can be just as nutritious for the hermit crabs as fresh ones.


Is watermelon juice safe for hermit crabs to consume?

If watermelons themselves are safe for your pet crabs to consume, there is no reason why they cannot drink their juice. Moreover, since watermelons are practically all water, blending their juice is much easier and less time-consuming than other fruits.

However, if you’re planning on sharing your watermelon juice with your hermit crabs, there are a few things you might want to know beforehand. The first concern is the seeds of watermelon. While most of you already remove all seeds from watermelons before blending their juice, when making it for your pets, you need to be extra careful.

As we’ve already mentioned above, these seeds contain a small amount of amygdalin which, when broken, converts into hydrogen cyanide and be lethal for the health of your pet friends.

Another thing you must keep in mind is never to feed them store-bought watermelon juice. These juices are highly processed and contain many added preservatives and additives, not the extra added sugar. While these additives are safe for human consumption, they can harm your pet’s health.


Watermelon for hermit crabs: feeding ideas

Now that we’ve covered almost all grounds of feeding watermelons to hermit crabs, what remains is discussing how to feed these fruits to them. It is not as difficult as it might sound. Below are some pointers that might be helpful when you’re feeding them watermelons for the first time:

  1. When you’re purchasing watermelons to feed your pet crabs, make sure to go for the organics grown in a controlled environment and are free from all kinds of toxic chemicals like pesticides and insecticides. This should be followed not only with melons but with other fruits and vegetables as well.
  2. The second step is washing the fruits. If you’ve bought organic watermelons, simply washing them in running water would be fine. But in the case of commercially grown watermelons, use de-chlorinated water for washing them.
  3. Once the melons are washed and ready, you can extract their inner flesh for your pets. You can do this in many ways. You can either scoop it out using a spoon or cut it into little, bite-sized cubes for them. However, we’d recommend you to go with the former for more convenience. Once the flesh has been taken out of its rind, remove all its seeds carefully. The melons are now ready to be served to your pets.
  4. If your crabs have left behind some of the melons (which doesn’t usually happen), make sure to remove them first thing the next morning.
