Aquarium, Terrarium, Fish Tank Accessories & Decorations

The Underwater Potter is a distinctive accessory shop supplying handmade stoneware hides for your aquariums and terrariums.  These unique playground structures provide stimulation and a sense of safety for your fish, reptiles, rodents and arachnids.  

More than just eye-candy for the avid aquarist, these stunning caves also serve as fish feeding stations.  Most pieces are designed to hold sand, which fish love to dwell upon, sift through, and feed from.  Feeding upon sand allows fish to protect their delicate mouths and keeps sinking pellet debris to a minimum.  

Towers can be stacked to create statuesque seascapes.  Tunnels can be linked together to yield elaborate mazes for your aquatic friends to explore.

Furthermore, if you’re having issues with larger fish taking food from smaller fish, custom-sized holes can be created to allow for exclusive feeding.

Come explore our shop to find your ideal stoneware hide!
