Cliff Castle Glow! has an enormous cave opning that has a matching opening on the back so even larger fish can swim straight through! So it is basically a castle tower on a cliff cave complete with man made stairs that wind up to the tower or down to the sea depending on which way you are going. Along the parapets of the tower and running down the steep cliff stairs is glow glaze!  Use an aquarium light or a desk lamp and the glow glaze will absorb the light and Glow in the Dark as you can see in the image above!
 perfect for any fish bowl or small aquarium.
