The quickness

I was surprised with how quick this item arrived! Also I was surprised to see how the sponges were packed. Very condensed and just made sense.

Keeping Hermits happy & hydrated

At first glance, these sponges come in the form of flat disks that look nothing like sponges. But add some water, and voila! They transform into functional sponges

At first glance, these sponges come in the form of flat disks that look nothing like sponges. But add some water, and voila! They transform into functional sponges. What's more, I've observed that the humidity in my tank stays consistently higher with these sponges in place. Now, regarding my hermit crabs, they've been going through a molting phase since I introduced the sponges, so I can't say for certain how they feel about them. However, overall, I'm quite pleased with their performance.

won’t do much

This sponge won’t do much, after doing some research, sponges do nothing but hold bacteria and can grow mold over time, hermit crabs need both salt and fresh water pools and those pools no matter the size will help with keeping your hermit crabs healthy and hydrated and keep up the humidity in the tank
