A little architecture below the surface
Hide a secret room beneath your tank landscape.
Secret House combines an underground cave with architectural detail. Bury the body beneath sand or fine gravel and leave the doorway, window, and rugged upper edge visible to create the look of a hidden dwelling built into the terrain.
It adds narrative character to freshwater aquariums, shrimp and betta tanks, terrariums, planted aquascapes, fantasy layouts, and display builds without sacrificing usable shelter space.
Underground room
Uses the substrate layer to conceal a surprisingly spacious interior.
Storybook detail
Rock texture and masonry-inspired surfaces give the aquascape a hidden-world feeling.
