The lava rocks arrived quickly and look very natural. My betta fish now has a place to hide and the Java Fern is growing well. The porous surface seems to help with water stability.

I used these rocks to build a small aquascape. They fit well in the tank and the plants are thriving. The texture is great for root development and the fish seem calmer now.

Perfect for beginners. Easy to arrange and the rocks hold up well in the water. My Anubis plant has grown longer roots since I added them.
