Dragon Stone vs Lava Rock vs Alternatives: What to Choose?
Choosing the right hardscape is a game changer for any aquascape. Whether you’re a seasoned aquascaper or just starting your first planted tank, your choice of rock and substrate lays the foundation for your aquascaping masterpiece. In this guide, we compare Dragon Stone, Lava Rock, and popular alternatives to help you make an informed decision for your aquarium.
Understanding the Essentials: Why Hardscape Matters
The hardscape forms the “bones” of an aquascape. Rocks and stones not only provide structural support but also influence plant growth, water parameters, and fish behavior. That’s why selecting the right hardscape materials is vital for both aesthetic harmony and aquatic health.
Dragon Stone in Aquascaping
What is Dragon Stone?
Dragon Stone, also known as Ohko Stone, is a favorite among aquascapers. Recognized for its earthy color and rugged, scale-like texture, Dragon Stone brings a natural, dramatic appearance to aquariums, especially in Iwagumi layouts.
Pros of Dragon Stone

- Fish and Shrimp Friendly: Smooth surfaces minimize the risk of injuries.
- pH Neutral: Minimal effect on water chemistry, making it safe for most aquatic species.
- Lightweight: Easier to handle and position compared to other stones.
Cons of Dragon Stone
