WIO 다윈 블랙 라바 나노 스톤 1.5kg

The porous texture grips plant roots perfectly, and the dark lava color makes my tetras really pop against the black background. I spent a good hour arranging the pieces into caves and crevices for my shrimp to explore.

The texture on these rocks is incredible—my cichlids love weaving through all the nooks. They’re lighter than regular stone, so stacking them felt surprisingly easy. A solid natural look without weighing down the tank.

Finally got these arranged in my tank and the crevices they create are perfect for my shy corydoras. The porous surface seems really good for beneficial bacteria, and the dark color makes my plants pop.
