Creating an Iwagumi aquascape is a wonderful way to make a beautiful rock garden in an aquarium. This style uses a few carefully selected rocks to create a natural and peaceful look. To start, you need to choose three main rocks of different sizes – a large one, a medium one, and a small one. These rocks should be placed in a triangle shape to look balanced and nice. Next, you will add some small plants around the rocks. These plants will help make the aquarium look more like a real underwater garden. It’s important to use only a few types of plants and to keep the look simple. This makes the Iwagumi style unique and elegant. With patience and care, you can create an aquascape that brings the beauty of nature right into your home.
Best Rocks for an Iwagumi Aquascape
When selecting rocks for an Iwagumi aquascape, picking ones that go well together and make your tank look good is crucial. Here are some types of rocks that are great for Iwagumi layouts:
Rock No. 1: Seiryu Stone
Seiryu Stone is popular because of its rough texture and bluish-grey color. It has cool veins and crevices that look natural and blend well with aquatic plants.
Rock No. 2: Ryuo Stone
Ryuo Stone is another good choice. It looks rough and old with mostly white and off-white colors, which can add contrast and character to your aquascape. This rock often has sharp angles and dramatic shapes, perfect for dynamic layouts.
Rock No. 3: Ohko Stone
Also known as Dragon Stone, Ohko Stone has a greenish-brown color and intricate surface textures with lots of holes and crevices. Its unique look allows moss and small plants to attach easily, making your aquascape feel more natural.
Rock No. 4: Lava Rock
Lava Rock, or Scoria, has a dark, porous structure that looks cool and is also good for your aquarium’s ecosystem. Its porous nature provides a great home for beneficial bacteria, helping to keep the water clean.
Best Substrate for Iwagumi Aquascape
Choosing the right dirt for your Iwagumi aquarium is important for your plants and how your tank looks. The dirt helps your plants grow and gives them nutrients. Here are some good options for Iwagumi layouts:
1. ADA Aqua Soil Amazonia
This dirt is popular because it has lots of nutrients, helping plants grow well. Its dark color also makes the green plants and rocks look better.
2. CaribSea Eco-Complete
Eco-Complete is great because it has good bacteria that help start the tank’s cycle. Its black color makes a nice, natural-looking base for plants and rocks.
3. Fluval Stratum
Fluval Stratum is good for planted tanks because it has lots of minerals. Its light and porous texture makes it easy for plant roots to grow and get nutrients. It also helps keep the water’s pH level balanced.
4. Seachem Flourite
Seachem Flourite is a clay-based dirt that supports plant growth well. It lasts a long time and can be mixed with other dirt for more nutrients. Its reddish-brown color gives the tank a natural earth-tone look.
Step-By-Step Instruction to Create a Beautiful Rock Iwagumi Aquascape
Step 1: Select a Suitable Aquarium Tank
Start with the right tank. Iwagumi aquascapes usually thrive in shallow, wide tanks that allow for a low water level. This setup gives the rocks space to stand out truly.
Step 2: Choose Your Rocks Carefully
Rocks are the heart of an Iwagumi aquascape. Pick rocks that vary in texture, shape, and size to make them look interesting. A mix of these elements will give your aquascape a more natural yet simple look.
Step 3: Prepare the Substrate
A nutrient-rich substrate is important for plant growth. Fine sand or gravel works well for Iwagumi setups. Level the substrate to ensure a neat and uniform base for your aquascape.
Step 4: Arrange the Rocks
Follow the “rule of thirds” for rock placement. Place the largest rock, called the “father” stone, at one-third of the tank. Put the smaller rocks, or “mother” and “child” stones, in the remaining two-thirds of the tank. This arrangement creates a balanced and nice-looking setup.
Step 5: Create a Sense of Depth
Vary the height and positioning of the rocks to add depth to your aquascape. This will make the setup look more natural and three-dimensional.
Step 6: Add Aquatic Plants
Choose a few types of carpeting plants to create a lush, green foreground. Plant these between the rocks to enhance the natural look. Common plants for Iwagumi include Glossostigma elatinoides and Eleocharis parvula.
Step 7: Fill the Tank with Water
Fill the tank slowly to avoid disturbing the substrate or uprooting the plants. This careful approach will keep the water clear and the aquascape intact.
Step 8: Install Lighting and Filtration
Proper lighting is important for plant growth. Install lighting that matches the needs of your chosen plants. Also, set up a filtration system suitable for your tank size and the number of fish you plan to keep.
Step 9: Monitor and Maintain the Aquascape
Regular maintenance is key to a healthy and beautiful Iwagumi aquascape. Check water parameters, trim plants as needed, and perform regular water changes to keep the environment balanced and flourishing.
Best Plants for Iwagumi Aquascaping
Plant No. 1: Dwarf Hairgrass (Eleocharis parvula)
Dwarf Hairgrass is a favorite for carpet plants in aquariums. It looks like fine grass and creates a green carpet that looks like a natural meadow. It grows quickly with good light and spreads by sending out runners, making it easy to get a uniform look.
Plant No. 2: Dwarf Baby Tears (Hemianthus callitrichoides)
Dwarf Baby Tears is another great carpet plant. It has small, bright green leaves that form a dense mat on the aquarium floor. It needs a lot of light and CO2 to grow well.
Plant No. 3: Monte Carlo (Micranthemum Tweediei)
Monte Carlo is a flexible carpet plant that can grow in different conditions. Its small, round leaves make a bright green carpet that can cover rocks and the bottom of the aquarium. It is less difficult to care for than Dwarf Baby Tears, making it good for beginners.
Plant No. 4: Anubias Nana Petite
Anubias Nana Petite is a small, slow-growing plant perfect for placing on rocks. Its strong, green leaves can attach to rocks and wood, adding green without taking over the space. It grows well in low to medium light.
Plant No. 5: Staurogyne Repens
Staurogyne Repens is a tough, low plant with bright green leaves. It is great for the middle of the aquarium and gives a bushy look that fits well with simple layouts. It is easy to care for and can grow in many conditions.
Plant No. 6: Needle Spikerush (Eleocharis Acicularis)
Needle Spikerush is another good carpet plant. It has thin, needle-like leaves that make a soft, natural cover on the bottom. It grows well with good light and CO2 and can be trimmed to keep it neat.

FAQs
Q1. Can I use tap water for my Iwagumi aquascape?
Yes, you can use tap water for your Iwagumi aquascape, but you need to treat it with a water conditioner to remove chlorine and other harmful substances. Also, check the water’s pH, GH, and KH to make sure it’s good for your plants and fish.
Q2. How often should I trim the plants in my Iwagumi aquarium?
How often you trim depends on how fast your plants grow. Fast-growing plants like Dwarf Hairgrass and Monte Carlo might need trimming every week or two. Slower-growing plants like Anubias Nana Petite can be trimmed about once a month.
Q3. What kind of lighting is best for an Iwagumi aquascape?
The best lighting for an Iwagumi aquascape is full-spectrum LED lights that help plants grow. Aim for a light intensity of around 30-50 PAR at the bottom of the tank. The light should have a color temperature between 6,500K and 8,000K to look like natural daylight.
Q4. How do I prevent algae growth in my Iwagumi aquarium?
To prevent algae, keep a balance between lighting, nutrients, and CO2 levels. Use a timer for 6-8 hours of light each day, don’t overfeed fish, and change the water regularly to avoid nutrient buildup. Adding algae-eating creatures like Amano shrimp or Otocinclus catfish can also help control algae.
