Evergreen Pet Supplies4-Pack of Natural Hermit Crab Sea Sponges - All Natural Sponge for Crabs - Assists Safer Drinking, Provides Nutrients, Balances Tank Humidity

These sponges are a great value, and work perfectly for our hermit crabs. We’ve had them for about a month and the one we put in with them is holding up well. They do a great job of absorbing a good amount of water which is great, and out of the package we recieved there were some different sizes which allowed us to pick the one that would work best at the moment based on our crabs sizes. Will buy again if I need more!

These work well. I'm new to having hermit crabs and using these but they seem to like them so far. They last awhile. I felt they are a little pricey but if it works, it works.

Can not recommend more! Much better then the original sponge from the pet store. They retain much more moisture as they soak up water like a sponge!**** Only received two sponges in the bag and sent an email to support. I was sent a pack of four right away and could not be happier with the service provided. Prompt and understanding. I could not ask for any better!"

My hermit crabs love these sponges! We bought 5 hermit crabs on vacation several years ago with the expectancy that they would live a few months. That was several years ago! These sponges have worked well with our hermit crabs for years! I highly recommend.

The sponges for my spider was just bout 4 to 6 inches round. They were just the right size for her water dish. The water was able to be absorbed very easily in the sponge.

The sponge is a little hard. I had to soak them first before I put them in the bowls. But the crabs like them. So I guess it was worth the buy. To pricey in my book.

First order never made it but Amazon always makes it right. These are pretty amazing for the price. Wet them and put them in my hermit crabs bowl and they loved them.

I wish these were a little cheaper, but Kirby, our hermit crab, gobbles them down (not sure if he's supposed to, but can't imagine how I would stop him, and he needs one in his water bowl), so they must be good?
