Commonly Used and Beautiful Types of Aquascaping Rocks
There are many types of aquascaping rocks on the market today, but not all are suitable for a stable aquatic environment. Below are the most widely used and visually impressive rocks, trusted for their aesthetics and compatibility.
Dragon Stone (Ohko Stone)
Dragon Stone, or Ohko Stone, is one of the most beautiful and popular types of aquascaping rocks. With its reddish-brown tone and porous structure, it brings a wild and mountainous feel to the aquarium.

Lightweight and easy to arrange, Ohko Stone doesn’t affect pH or hardness, making it ideal for beginners. When paired with low-growing aquatic plants like dwarf baby tears, moss, or dwarf hairgrass, the layout becomes vivid and harmonious.
Lava Rock
Lava Rock is a volcanic-origin rock with a porous surface and dark color (black or deep red). One of the most functional types of aquascaping rocks, it provides abundant surface area for beneficial bacteria.

This helps improve water quality and enhances biological filtration. Lava rock is used in both substrate and layout structures—especially in shrimp tanks or low-tech setups—thanks to its neutral impact on water chemistry.
Sedimentary Rock
Sedimentary rocks come in diverse shapes and natural colors like earth yellow, reddish-brown, or ash gray. Formed through the accumulation of natural minerals, they bring a rustic and authentic appearance to the tank.

When arranged cleverly, sedimentary rocks create a layered terrain effect—perfect for mountain or cave-style layouts. Among the many types of aquascaping rocks, this is a great choice for aquascapers who prefer a natural but not overly rugged style.

Quartz, or Chert, is known for its high hardness and white to translucent color. Its standout feature is its chemical inertness—it does not dissolve or react in water, making it extremely safe for planted aquariums.
