Dragon rock—also known as Ohko stone—is a lightweight, earthy-brown stone with a distinctive, dragon-scale texture full of holes and crevices. It’s popular in aquascaping and terrarium design for its weathered, ancient look.

In terrariums, dragon rock is great for:

• Creating rugged, natural landscapes

• Providing texture and depth

• Pairing with mosses and small plants that grow in its crevices

It’s lighter than Seiryu rock and won’t affect pH, making it a safe choice for most terrarium setups. Use it to build cliffs, valleys, or cave-like features—its unique surface adds instant character and a wild, earthy feel.
