Detailed Exploration of Setting Up an Iwagumi Tank

Creating an Iwagumi aquascape involves several detailed steps. Let’s break them down!

Choosing the Right Aquarium

Start with a clear glass tank to best display your aquascape. The size is up to you but remember, larger tanks are generally easier to maintain once set up.

Substrate Selection

Positioning Your Stones

Position your main stone first. It should be the largest and most impressive. Supporting stones are placed in a way that complements the main stone, usually in odd numbers to maintain natural asymmetry.


Plant your chosen aquatic plants while the aquarium soil is still dry. Once planting is done, gently fill the tank with water to avoid disturbing the setup.

Examples and Case Studies

Example 1: A Successful Iwagumi Setup

A 20-gallon tank featuring a dramatic Ryuoh stone as the main stone, complemented by smaller Seiryu stones, and planted densely with Dwarf Hairgrass. This setup took about 6 months to fully mature, resulting in a breathtaking, lush green carpet.

Example 2: Common Challenges

Often, beginners struggle with algae due to inadequate lighting and nutrient imbalances. It’s crucial to monitor and adjust your lighting duration and intensity, and consider CO2 supplementation for better plant growth.
