Use the back wall as terrain
Build a coastal rise instead of a flat tank floor.
CoastDune creates a strong vertical transition with a rugged wall on one side and a raised shelf ready to carry sand, stones, moss, or plants. A tucked-away lower opening gives the structure a functional cave beneath the scenery.
Place it near a back or side wall in freshwater tanks, betta and shrimp setups, terrariums, planted aquascapes, and displays that need height and a more dramatic substrate profile.
Hidden lower cave
Creates a sheltered opening beneath the visible landscape.
Tall rocky wall
Introduces height and a strong backdrop within the aquascape.
