Aquascaping Contest Prep: From Hobbyist to Competitor

You have been aquascaping for a while. Your tanks look good, friends and family are impressed, your Instagram posts get solid engagement. And then you see competition results from IAPLC (International Aquatic Plants Layout Contest) or AGA (Aquatic Gardeners Association) and realize: there is an entirely different level. Entering a contest is not about winning (especially your first time), it is about pushing your skills, learning from the best, and joining a global community of obsessed aquatic artists.

Major Aquascaping Competitions

The Timeline: 6 Months Before Submission

Month 1: Concept and Planning

Study previous contest winners. Identify the style you want to pursue (nature style, Iwagumi, diorama, biotope). Sketch layouts on paper, at least 5 to 10 different concepts before committing. Choose your tank size (larger tanks score better in open categories, but small tanks have dedicated categories too).

Month 2: Hardscape and Planting

Build the hardscape. Take photos from the front view after every significant change. The hardscape should look like a compelling landscape even without plants. Plant the initial species, backgrounds, midgrounds, and start the carpet (consider the dry start method for carpet plants).

Month 3-4: Growth and Refinement

Let plants grow in. Trim regularly to develop shape and density. Replace any species that are not performing. Adjust lighting, CO2, and fertilization based on plant response. This is the patience phase, resist the urge to change the layout fundamentally.

Month 5: Final Adjustments

The layout should be 90 percent complete. Fine-tune plant positions. Remove any algae aggressively. Consider adding final detail plants, small epiphytes, moss accents, or a subtle foreground transition. Do a major water change and glass cleaning.

Month 6: Photography

The photo is what judges see. Read our aquascape photography guide and dedicate a full session to getting the best possible image. Most competitions accept only one photo, make it count.

What Judges Look For

Composition (30-40% of score)

• Clear focal point with supporting elements
• Sense of depth and perspective
• Balanced but asymmetrical arrangement
• Effective use of negative space
• Natural flow and visual pathways

Plant Health and Selection (20-30%)

• Healthy, algae-free plant growth
• Appropriate species selection for the style
• Color variety and contrast
• Proper trimming and maintenance evident

Creativity and Impression (20-30%)

• Original concept or unique interpretation
• Emotional impact, does it evoke a feeling?
• Natural appearance (does not look staged)
• Overall atmosphere and mood

Technical Execution (10-20%)

• Photo quality (sharpness, lighting, color accuracy)
• Clean glass, no visible equipment
• Fish selection appropriate to the environment
• No visible algae or maintenance issues

Common Mistakes in Competition Entries

• Over-reliance on diorama scale tricks: Miniature houses, tiny figurines, and forced perspective are overdone. Judges have seen thousands of these. Natural layouts score consistently higher.
• Poor photo quality: Reflections, blurry images, or visible equipment immediately lower scores. The photo IS the entry.
• Rushing the grow-in: Submitting a layout that is not fully mature. Thin carpets, sparse stems, and visible substrate through plant gaps signal an incomplete layout.
• Ignoring the foreground: Many entries have strong backgrounds but empty, flat foregrounds. The foreground is what grounds the composition.
• Copying famous layouts: Judges recognize copies of Amano's or other famous aquascapers' work. Be inspired, but create something original.
