A cove with more than one way in
Layer caves, tunnels, and terrain into one form.
DuneCove uses an irregular, weathered surface to create several protected spaces within one low formation. Work sand, stones, plants, and moss around its perimeter to soften the edges and deepen the natural cove effect.
Its multi-opening design is suited to shrimp, bettas, bottom dwellers, nano fish, freshwater tanks, and planted layouts that benefit from more routes and viewing angles.
Porous rock texture
Adds depth and shadow without a rigid geometric outline.
Landscape-ready base
Pairs naturally with sand, gravel, plants, moss, and stone.
