Its not just for Reptiles & Amphibians any more! Its like a Crab Spa. I like to try other products I think could work well for the Hermies. *Stimulate all tropical & Forest dwelling *Creates terrarium Humidity (vent lid) *Can be used with any air pump (small works best) *Fits in terrarium corner & Easy to Clean *Habi-Scape rock texture saves pet from drowning I use a natural sea sponge over the top of the air stone to reduce splashing on the glass or water getting into the substrate too much. This product can be found in the Reptile Dept of most PetsMart stores for about$12.oo its a PET-Tech Product. I love the idea of keeping the water moving.
