Natural Conch Shell Fish Tank Aquarium Landscaping Decoration Size Shell Underwater World Ornaments Shelter

Small thorn snail size fits my nano tank just right. The 5x4x4 cm shell gives shrimp a cozy hide and the texture pops under light.

I chose the large thorn snail and the 20x12x11 cm size stands out on the sand bed. Looks like a real bit of the sea in the tank.

Edges are smooth and the natural pattern really shows underwater. It gives fish a cool tunnel to pass thru and makes the scape feel complete.
