Crab not eating or bathing itself/drinking?

[topbunkbear]

I supply my crabbies with salt and fresh water, and because of my Ecoearth substrate I can tell if they go into the food or water dishes as they leave a little trail. I change out the food every 2-3 days and I change the water either when it's dirty or every 4 days.

I've had my hermit crabs for 2 months and 2 weeks respectively, and I haven't seen them eat or noticed any food missing...ever.
Why is this? Is it okay?

Thanks!

What types of food are you feeding them? Crabs can devour certain things at one feeding then not touch it for several more. They do like a variety since they are scavengers. Depending on what you are feeding them several options of plants, veggies, animal/fish proteins, nuts/seeds and calciums may encourage them to eat more.

I generally feed mine 2-3 options of each food type above. Then change up the next feeding. I will also toss organic apple cores, and other fruits I eat for them to pick at. Those are usually well received. I also keep a journal of what I feed my guys and note what they eat and let sit. That way I know what to not order again.

Every crabs food preferences are different so it may take some samples in order to find what they like. I highly recommend foods from The Healthy Hermit on Etsy. The one moderator on here, Gotbutterflies , runs it. I believe you can get do a custom order of little sample packs to try a bunch of different foods. There are a ton of food shops on Etsy and eBay. If you click on the link in my profile it will take you to a lot of food stores.

Perhaps you are also giving the two crabs a lot more than what they can eat in a day or two. That could make it more difficult to see what they have been eating.

You can also take a picture of the food dish when you first put it in the tank. Then compare that to what it currently looks like.
