Checklist: Judging Criteria Explained – Setup Done Right

Are you looking to elevate your aquascaping skills and create aquariums that truly stand out? Whether you’re entering a contest or perfecting your next setup, understanding the official judging criteria can make all the difference. In this comprehensive guide, we break down the elements judges look for, explain how to check your own work, and offer expert aquascaping tips for achieving a visually stunning, healthy, and competition-worthy aquascape.

Why Judging Criteria Matter in Aquascaping

Competition aquascaping is all about the details. The criteria used by expert judges help set the gold standard, ensuring that each aquarium is evaluated for both beauty and ecological health. By understanding and applying these benchmarks—even in your home tank—you can create more balanced, aesthetically pleasing, and sustainable aquascapes.

Essential Aquascaping Judging Criteria: Your Master Checklist

The following checklist is based on the most common standards used in international aquascaping competitions. Use these criteria to evaluate your current setup or guide you through your next project.

1. Composition & Layout

• Balance: Does the aquascape show visual harmony? Achieve balance with the strategic placement of hardscape and plants.
• Focal Point: Is there a clear “center of attention” or highlight in the layout? Effective use of the rule of thirds can help.
• Depth: Does your layout create an illusion of space? Layering, perspective, and gradual plant height transitions help add depth.
• Flow: Are the lines, curves, and hardscape elements guiding the viewer’s eye smoothly through the scene?

2. Plant Health & Arrangement

• Vibrancy: Are aquatic plants lush and vibrant, free from algae or nutrient deficiencies?
• Diversity: Is there a thoughtful mix of species, textures, and colors without overcrowding?
• Pruning: Are stems and leaves carefully shaped and maintained for a natural look?

3. Hardscape Integration

• Naturalism: Are rocks, wood, and substrate positioned to look natural and stable, integrating seamlessly with plant choices?
• Creativity: Does your hardscape tell a story, evoke a landscape, or present a unique artistic theme?
• Scale & Proportion: Are hardscape elements suitably scaled to the aquarium and to each other?

4. Technical Execution

• Cleanliness: Crystal-clear glass, clean substrate, and healthy water parameters are non-negotiable for high scores.
• Equipment Visibility: Have you minimized the appearance of filters, heaters, and other hardware?
• Maintenance: Ongoing care should support long-term aquascape health, keeping all aspects in pristine condition.

5. Ecological Stability

• Healthy Fish & Invertebrates: If livestock is included, they should appear healthy and complement the aquascape design.
• Sustainable Setup: Has the tank matured naturally, with stable plants, cycling, and minimal visible algae?

How to Self-Evaluate: Use the Checklist for Setup Success

Before submitting your tank to a contest or sharing it online, walk through each of the above judging criteria:

1. Take photos from several angles and compare them to reference layouts.
2. Check plant health under bright light for signs of algae or deficiency.
3. Review hardscape placement—ensure nothing looks out of place or artificial.
4. Observe flow and depth—do viewers’ eyes move naturally through your scene?
5. Test water parameters for ammonia, nitrate, CO₂, and more to confirm ecological stability.

Pro Tips to Impress the Judges

• Patience is key: Allow your setup to mature; rushed aquascapes are easy to spot.
• Less is often more: Avoid clutter and focus on highlighting key features.
• Document your process: Keeping before-and-after photos helps you identify improvements and catch mistakes early.
• Participate in community feedback: Share your setup in online aquascaping forums or our Community Showcase for constructive critique.

Common Mistakes to Avoid

• Ignoring the growth patterns of fast-growing aquatic plants
• Forgetting to sync livestock choices with your aquascape style
• Neglecting hardscape anchoring, leading to shifts or collapse
• Over-lighting, which can trigger unwanted algae blooms
