YARNOW3Pcs Aquarium Mountain Rock Ceramic Ornament Mini Mountain Miniature Figurines Sand Table Mountain Model Micro Landscape Decorations

I used to the pieces as o ppl art of an HO scale diorama.

These aquarium micro mountains are exactly as they sound, very small. They are pretty much exactly as they show in the listing. They are ceramic and would work in any size tank as long as you don't mind how small they are. They do have good detail on them for the size and look like nice mountains. Any additional ceramic decorations is helpful for my shrimp and snail tank as it gives some fun and extra surface area for biofilm and algae to grow on.

I thought they were bigger
