Do you want to add an exotic touch to your aquarium? Dragon Rock Aquarium “Ohko Stone” has just what you need!

When I first set up my aquarium, I struggled to find rocks that would fit the space and give the right look. My husband suggested Dragon Rock Aquarium, and I’m so glad he did.

Every time I walk by my aquarium now, I can’t help but smile! So I’ll share the Dragon Rock Aquarium love with you and tell you about it.

What Is Dragon Rock Aquarium?

A dragon stone is a sedimentary rock with a scaly, reptilian texture that gives it the look of dragon skin. As a result, most people believe that dragon stones are unnatural, but this isn’t true.

It is a lightweight aquascaping rock composed of silt minerals, clay, and organic matter that has settled together because of high-pressure waves.

Additionally, its rough and craggy surface resembles driftwood or petrified wood, making it a hot pick among aquarium enthusiasts!

Furthermore, the rocks harden and lose color as more clay and microorganisms accumulate. They are either olive green or brown in color, depending on the ratio of organic matter to clay content.

What Are Dragon Rock Origins?

These rocks typically originate from the shores of lakes, ponds, and oceans in Japan. Where rough seas and plenty of mud make it a perfect location for dragon stone formation.

However, these dragon stones are rare since the process of their formation can take decades!

Thankfully, there are also dragon stones from Utah, Canada, and the U.K. that are ideal for a home aquarium setup. They’re safe for your fish and even cheaper than rocks from Japan.

What Is Aquarium Dragon Rock Appearance?

Dragon stone is characterized by its scaly, dragon-like texture. The surface is covered in natural indentations of different depths. 

Also, the high-pressure waves that create this rock leave behind small holes and divots in the soft sections of the stone.

Over time, particulate matter chips away at the surface, leaving deep, rough marks.

On the other hand, the waves don’t bother the hard rock sections. With time, dragon rocks grow as pressure from tides forces sediment onto these areas.

In terms of color, they can be olive green or brown, depending on the amount of clay and organic material on the surface.

However, stones from outside the Ohko region are frequently easily identified because of their color. This region is a hotspot for Dragon stone. 

Instead of a mossy brown or green tone, they have more brilliant red, yellow, and orange colorations.

How To Prepare Dragon Stone for Aquariums?

Before adding dragon stone to your aquarium, prepare it first. This will ensure that your rock doesn’t leach any harmful chemicals into the water and that it won’t alter the pH levels.

To clean the rocks, start by filling a pail with cold water and rinsing them thoroughly in order to remove any superficial dirt and organic waste.

Next, use a water hose on medium pressure to clean the holes thoroughly and remove debris from them.

If there is anything stuck or trapped, you should use a soft toothpick or wooden skewer to remove it.

After that, clean each dragon rock until the water runs clear, without any dirt or pieces of stone. 

When you finish that, fill a container with nine parts water and one part bleach. Then, soak the stones in this solution for 10-20 minutes based on the size rocks to maintain simple rock formations of the stones.

Finally, rinse them thoroughly with tap water and place them in dechlorinated water for around 20 hours before adding them to the tank.

However, never use harsh chemical cleansers on dragon stones since they may seep into the pores and remain there, raising the pH of the tank water and making it more basic.

Instead, you can clean them with a diluted bleach or hydrogen peroxide solution to eliminate hazardous microscopic germs.

What Are the Benefits of Dragon Rocks?

Don’t Affect Water Chemistry

Dragon stones are inert and will not decay in the tank unless exposed to very high water pressure; hence they’re the best safe, all-natural materials for aquarium landscapes.

Also, they have a neutral pH, so they won’t throw off the concentration of hydrogen ions in the tank as corals or limestones do.

In addition, you can keep these rocks in a pH-sensitive planted tank or a freshwater tank without any problems.

However, the only disadvantage is that they may quickly accumulate waste on their inscribed surface.

Providing Hiding Places

The scaly structure of a dragon stone is attractive to the eye and practical. This is why many people use it for their aquascaping setputs. Its many nooks and crannies provide excellent hiding places for tiny aquarium animals such as shrimps, snails, and nano fish.

Besides, the slightly bigger fish can hide behind this structure from predators.

Furthermore, dragon stones create hardscape tanks, which provide fish living there with exploring and relaxing space. Some shy fish, such as bettas, enjoy these setups because they lessen tension.

Perfect for Plant and Moss Support

These stones are perfect for plant and moss anchors as their pores offer a lot of surface area for roots to grip onto.

Since the roots of the plants can grip onto any little nooks and feed off the organic material inside them.

Consequently, more plants will grow roots and make the plant life in the aquarium more robust.

In addition, plant roots will serve as an anchoring system, keeping the delicate stones together and preventing them from chipping.

What Are the Dangers of Dragon Rocks?

Tiny Fish Trapped in a Hole

Although the pores are big enough for fish to hide within, they may trap them sometimes.

Sometimes, small fish can become overwhelmed and lose their way inside the stones.

Therefore, you should select rocks with large enough holes for your small tank animals to move around freely.

Fragile and Likely To Fall Apart Easily

As I mentioned, dragon stones are large chunks of sediment and clay that have been fused together. This is why they can easily chip and crumble, which may frighten your fish pets.

To avoid this, do a crumble test once in a while. It’s really simple and will allow you to sleep well, knowing that your stones will stay intact and maintain their rock structures.

Simply put, soak the rocks in a water container from your fish tank for 24 hours. If the dragon stones retain their form, they are safe to put in the aquarium.

Aquarium Dragon Rock Design Ideas

Some people use large dragon stone rocks in their tanks as the primary decoration, while others like to shape them into different structures as hardscaping materials.

If you want to use small stones, just break them into small pieces to make towers, arches, caves, and more which serve as a natural material for scaly texture.

To break up a large piece of dragon stone is by wrapping it in a towel and hitting it with a heavier object, depending on its clay composition.

However, this may destroy some or most of the expensive stones. Instead, you can use a chisel to create setups with precision and control.

Where To Buy Dragon Rock Aquarium?

Dragon stones are available in local fish and aquarium shops, so you can simply go inside and get some for yourself!

Also, they’re available through several online retailers if you only want to buy them from the comfort of your own home. You can find them on Amazon, LiveAquaria, or FlipAquatics.


Is Dragon Rock Good for Aquariums?

Dragon rock is a good addition to any aquarium as it provides many benefits to the fish and plants living there. It can help clean the water, provide hiding places for shy fish, and support plant life hence a good fit for many acquascaping setups.

Does Dragon Rock Affect pH?

Dragon rock does not affect the pH of aquarium water. It is made of sediment and fresh clay, both neutral in terms of pH.

Do I Need To Boil Dragon Stone for Aquarium?

You don’t need to boil dragon stone before adding it to your aquarium since it can explode when heated too quickly.

Does Dragon Stone Dissolve in Water?

Dragon stone does not dissolve in water. It is made of sediment and clay, both insoluble in water.

Wrapping Up

Dragon stones are an excellent addition to any aquarium because they are visually appealing and offer many benefits to the fish and plants living there.

They provide plenty of hiding places and support plant life, and their reef structure can be used to create stunning aquascapes. Just be cautious, as they are fragile and may break easily!
