SunGrow Hermit Crab Tank Humidity Control Sponge, Yellow, 3 Count

Keep your hermit crabs nice and comfortable with SunGrow Hermit Sponge Humidity Control! This squishy sponge expands when it is placed in water and helps maintain the humidity level of your crab’s abode. This helps keep his gills moist so he can breathe when he’s out of the water. When placed in his water dish, it gives your pal a safe way to get in and take a drink without risk of drowning. He can even lap up water in the sponge whenever he needs a quick sip. You don’t need to worry about him ingesting any harmful ingredients when he naturally starts to nibble it—the sponge is made of harmless cellulose that is completely free of artificial additives. You can use it both inside and outside the tank.
