Design Decision Making: Complete Guide for Beginners

Starting your first aquascape can feel overwhelming with so many creative choices to make. Thoughtful design decision-making is key to creating an aquarium that’s beautiful, thriving, and uniquely yours. In this complete beginner’s guide from Aquascaping Academy, you’ll learn how to confidently plan layouts, choose materials, select plants, and build the aquascape of your dreams.

Why Good Design Decisions Matter in Aquascaping

Successful aquascaping blends art and science. Every choice—from the arrangement of stones and wood to the type of aquatic plants—impacts the health, balance, and appearance of your tank. Understanding the basics of design decision-making ensures your aquascape stays visually inspiring and easy to maintain.

1. Setting Your Aquascaping Goals

Define Your Aquascape Style

Nature Aquarium: Mimics natural riverbanks or forests, inspired by Takashi Amano’s works.
Iwagumi: Minimalist layouts focusing on carefully placed rocks.
Dutch Style: Colorful, lush plant rows and groups.
Biotope: Exact replicas of specific natural habitats.

Consider Tank Size and Location

The available space, lighting, and accessibility of your aquarium will guide key design decisions. A nano tank, for example, requires careful choice of smaller plants and hardscape, while larger tanks allow for more ambitious layouts.

2. Planning Your Aquascape Layout

Essential Aquarium Layout Principles

Great aquascapes incorporate proven design principles that please the eye and create harmony. These include:

Rule of Thirds: Imagine dividing your tank into a 3×3 grid. Place focal points off-center for natural balance.
Golden Ratio: Use a focal point roughly 1.6 times from one end, guiding the viewer’s gaze.
Depth and Perspective: Layer hardscape and plants from front to back, using smaller items in the background to enhance depth.

Sketch Your Plan

Create a rough sketch of your ideal scape. Consider where rocks, wood, and main plant groups will go. This not only helps visualize your design but also speeds up setup on the day.

3. Choosing Your Hardscape Materials

Popular Aquascaping Hardscape Choices

Rocks: Seiryu, Dragon stone, Lava rock, and Ohko are favorites for their unique textures.
Wood: Driftwood varieties like Spider wood, Mopani, or Malaysian wood add organic shapes and surfaces for plants.

Arranging Your Hardscape

Use odd numbers—3 or 5 stones/wood pieces look more natural than even groupings.
Anchor large rocks or wood as your focal point; then add supporting pieces around them.
Angle items slightly for a dynamic, non-symmetrical look.

4. Selecting Aquarium Plants

Factors to Consider

Light and CO₂ Requirements: Choose plants that match your setup and maintenance preference.
Growth Rate: Fast growers help outcompete algae but may need more trimming.
Foreground, Midground, Background: Arrange plants by size and growth habit to add visual layers to your aquascape.

Plant Placement Tips

Place carpeting plants like Hemianthus callitrichoides or Eleocharis acicularis at the front.
Mid-height plants such as Cryptocoryne and Anubias fill the tank’s midground.
Taller stems like Vallisneria or Rotala make lush backgrounds and add height.

5. Making Choices About Livestock

Your fish, shrimp, and other aquatic inhabitants are a vital design element. Some fish complement delicate plants, while others, such as cichlids or goldfish, might uproot them. Always research compatibility with your chosen aquascape layout and plant species.

Start with fewer species for easier care.
Patience pays off—allow your aquascape to mature and plants to fill in naturally.
Keep a maintenance routine for healthy growth and clarity.
