Hermit Crab Food Diet – The Hermit Crab Food Pyramid

What Hermit Crabs Eat

So what do hermit crabs eat?  Hermit crabs are omnivores, meaning they eat both meat and plant matter.  This great, meaning that hermit crabs eat just about anything!

Many hermit crabs in captivity are protein-deficient as their owners wrongly believe that their hermit crab only eats meat or only eats plant matter, so please make sure your hermit crab has a well rounded diet if you want him or her to live as long as possible.

Hermit Crab Food Pyramid

In captivity, hermit crabs are not known to be allergic to any particular type of meat, but owners need to be careful when preparing the meat of their choice.  Canned pet foods (for fish, turtles etc.) that have been freeze-dried are generally safe (e.g. shrimp, blood worms), but “hermit crab food” products should be avoided.

Organic vegetables and fruit provide plenty of nutrients for your hermit crabs, mango and coconut flesh are two popular hermit crab food choices.

"This book is very helpful for both the novice and experienced owner. I personally like to learn as much as I can on my pets.

This book explains the background of the species as well as how to care for them properly.

I hope someday people will start realizing that hermit crabs ARE NOT disposable pets that are meant to live in a little plastic container with a cm of sand.

They are so interesting little pets and can live a very long time if taken care of properly."
"I purchased this book as a gift for a friend who had just rescued a hermit crab from a content sale. She tried her best to save the little guy, but it didn't seem like things were going well.

Thanks to this book, she's been able to nurse Roger back to life. He's now an active, entertaining and engaging pet. With a much better quality of life than his little plastic box. If you've got crabs, buy this book. "
