CIAC 2025 Review: Six Lessons Before the 2026 Results

06 October 2026

599

Before the CIAC 2026 results arrive on October 10, there is time to look again at the aquascapes that made the previous season memorable. The most useful question is not simply which work finished highest. It is how each composition earned our attention—and what we notice when we return to it.

CIAC 2025 Review: Six Lessons Before the 2026 Results

This CIAC 2025 review brings together six works from the Aquascaping Group, spanning first to nineteenth place. Each offers a different lesson: guiding the eye through wood, protecting open space, using plant colour, arranging rock, shaping atmosphere with light, or giving fish a meaningful place in the image.

The selection is an editorial reading of the published photographs, rather than an explanation of the official scores. Explore the CIAC 2025 gallery alongside this article, then follow the linked AquaRank profiles to discover the people behind the layouts.

1. Build a route through the landscape

Veins of Nature 2 — Muhammad Yusuf, Indonesia — CIAC 2025, Rank 1

Muhammad Yusuf's winning aquascape makes a dense forest feel navigable. Large wood forms occupy the foreground, hanging roots interrupt the upper space, and a brighter opening draws attention into the distance. The eye has obstacles to travel around, but it also has a destination.

The curved wood establishes continuity between the near and far parts of the scene. Planting softens its surfaces while leaving enough of the structure visible to preserve that movement. The restrained sandy opening at the front provides an entrance into a landscape that might otherwise feel closed.

In his official CIPS interview, Yusuf identified the Petungkriono rainforest in Central Java as his inspiration. That context helps explain the scene's sense of enclosure and discovery.

The design lesson: establish a visual route before adding detail. Follow the main wood lines with your eye: do they carry you into the composition, or stop against unrelated objects?

For 2026: will the strongest forest layouts offer a fresh spatial experience as well as impressive construction?

2. Give the empty space a shape

The Pulse of Life — Gang Zhao, China — CIAC 2025, Rank 2

Gang Zhao, listed as Zhao Gang in the official interview, gives the central opening as much importance as the rock around it. Projecting shelves divide the scene into overlapping levels, while the pale background remains visible through a narrowing passage.

This negative space has an irregular outline. It changes width as the surrounding forms move forward and recede, giving the canyon a stronger sense of depth than a straight, uniform gap would provide. Dark undersides make the brighter planted surfaces appear more prominent.

The official judges' comments also discuss the layout's spatial structure. They include criticism of some planting details, a useful reminder that a highly placed work can still offer opportunities for refinement.

The design lesson: sketch the open space as carefully as the hardscape. Its contour, interruptions and connection to the foreground help determine how the whole aquarium reads.

For 2026: how will designers keep ambitious rock structures readable once the planting fills in?

3. Use plant colour to connect the composition

Eternal Blaze — Rahul Mukherjee, India — CIAC 2025, Rank 6

Eternal Blaze places warm tones within a predominantly green landscape. Reddish planting appears across the upper background and in smaller accents through the middle, creating connections between areas separated by wood and shadow.

The colour is effective because it has a supporting structure. Sloping wood and planted surfaces carry the eye through the scene; the warmer accents reinforce those relationships. Broad leaves, fine growth and moss-like textures also prevent the green areas from becoming a single visual mass.

The photograph shows how colour and texture can work together without making every planting group equally conspicuous. It does not establish the species used or the conditions that produced those colours.

The design lesson: decide where colour should lead attention. A repeated accent can connect the foreground, middle and background more effectively than one isolated patch added for contrast.

For 2026: will warm planting become an essential part of more compositions, or remain a finishing accent?

4. Make the rocks share a direction

Takachiho Gorge — Gustavo Pimenta do Nascimento, Brazil — CIAC 2025, Rank 10

Takachiho Gorge is a useful contrast to the more enclosed forest scenes. Its central rock mass projects above smaller surrounding forms, with dark exposed faces set against bright planting and a pale opening behind.

The stones differ in size, but several sloping edges create a related directional rhythm. Smaller rocks and low planting carry that rhythm into the foreground. A pale channel travels between these forms, helping the eye move from the front towards the brighter distance.

The vegetation leaves important rock faces visible. That restraint matters: covering every surface would weaken the shapes that give the landscape its character. The alternation of exposed stone and planted pockets gives the viewer enough information to read the terrain.

The design lesson: choose a dominant direction, then vary it. Supporting stones should contribute to the landscape's movement while retaining differences in angle, height and spacing.

For 2026: can a relatively open composition hold attention through strong structure and precise detail?

5. Let light reveal the structure

The Returning Breeze — Lich Do, Vietnam — CIAC 2025, Rank 15

The Returning Breeze — Lich Do — CIAC 2025, Rank 15. Published contest photograph from the AquaLibs archive.

The Returning Breeze is organised around a contrast between a bright upper opening and a darker lower landscape. Long, planted forms cross the aquarium diagonally, while the reflected surface extends the luminous area above them.

Light helps separate those forms. Green growth remains readable against dark recesses, and the brighter background provides a reference point beyond the foreground structure. The effect gives the photograph a sense of movement without requiring a conspicuous central path.

The image cannot tell us exactly how the lighting or photography was arranged. What it does show is the value of tonal separation: different parts of a complicated composition remain distinct because they are not all equally bright.

The design lesson: use contrast to reveal relationships. A dark area should support an adjoining shape or suggest depth; too much uniform darkness can conceal the design you worked to build.

For 2026: which photographs will use atmosphere while still preserving enough detail for a closer look?

Explore Lich Do's AquaRank profile, listed as Do Lich.

6. Give fish a visible role in the landscape

Lost World — Raúl Gargallo — CIAC 2025, Rank 19

Lost World — Raúl Gargallo — CIAC 2025, Rank 19. Published contest photograph from the AquaLibs archive.

Lost World frames a bright background opening with a substantial overhead wood structure. Beneath it, planted ledges, exposed roots and stones create a landscape with several levels of enclosure.

Small blue and reddish fish are especially noticeable against the darker water around the lower middle and right. Their scale helps the large wood forms read as a surrounding landscape, while their colour gives the eye another reason to explore the foreground.

Their position in this photograph also shows why fish presentation deserves attention alongside hardscape and plants. Fish need visible space within the composition; if every part of the image is equally crowded or bright, their contribution can disappear. A single photograph, however, cannot establish schooling behaviour or long-term suitability.

The design lesson: consider fish as living inhabitants throughout the design process. Appropriate care comes first; visual scale, contrast and swimming space can then strengthen how the finished aquarium is presented.

For 2026: which works will make the relationship between fish and landscape feel especially convincing?

Explore Raúl Gargallo's AquaRank profile.

What should we look for when CIAC 2026 is revealed?

These six works offer different answers to the same design challenge: how to make a small, bounded space feel coherent, expressive and alive. Their most useful lessons emerge from relationships—wood and distance, stone and open water, colour and texture, light and shadow, fish and their surroundings.

They also suggest a way to approach the new results. Look first at the whole image. Then trace the route through it, examine the transitions between materials and planting, and notice where the fish become visible. Finally, return to the overall impression: do the details strengthen it?

The official CIAC schedule lists October 10 as the 2026 results date. Until then, the previous season remains an excellent place to look, compare and learn.

Spain at IAPLC 2026: Roberto Buenadicha’s Forest and the Space Between Trunks

Roberto Buenadicha’s aquarium is the only Spanish work in the published ranks 1–300. Its slender dark trunks, fine green planting and conspicuous pale fish make it a rewarding individual study. This instalment returns to the older Spain introduction through one photograph, keeping the scope small enough for the evidence available.
France at IAPLC 2026: A Close Reading of Jean Christophe Grosset’s Woodland

Only one French work appears in the published ranks 1–300. That gives this instalment a different task: a close reading of Jean Christophe Grosset’s aquarium, with the older country introduction as context. The photograph deserves attention for its own wood, planting and fish relationships, rather than being made to represent every French aquascaper.
Singapore at IAPLC 2026: Open Stone and an Enclosed Planted Passage

Two Singaporean works appear in the published ranks 1–300, and they offer an unusually clear contrast. One makes open water and two main stones central; the other encloses a small rear opening within dense planting and roots. The pair is useful precisely because it does not support one simple visual label.
Hong Kong at IAPLC 2026: Three Studies in Light, Layers and Visual Impact

A low timber ceiling, blue-toned terraces and converging planted diagonals create three visibly different aquariums. Hong Kong’s represented works at ranks 1–300 offer a compact study of visual impact beyond the season’s leading awards. Looking at them closely is more informative than treating the cutoff count as a verdict on an entire aquascaping community.
Italy at IAPLC 2026: Calm Routes and More Dramatic Planted Frames

A clear route through planted banks can feel quiet; a coloured ridge beneath a dark frame can feel theatrical. The four Italian photographs selected for this study offer both experiences. Together, they make a useful contemporary comparison with an archive that once placed particular emphasis on calm, enduring-looking compositions.
United States at IAPLC 2026: Four Distinct Readings of a Wooded Aquarium

The four American photographs selected here all contain important wood structures, yet they do not produce one uniform wooded scene. A broad canopy, a low diagonal, a fine-leaved light window and an exposed timber subject organise attention differently. That variation lets us discuss design diversity through specific decisions rather than a broad national label.
Germany at IAPLC 2026: Four Ways to Balance Hardscape and Open Water

A dark wooded frame, a rocky valley, a brighter mixed scene and green-covered root contours make this German selection particularly useful for comparison. The photographs share an interest in separating materials from the water around them, but achieve it through different outlines and lighting relationships.
Taiwan at IAPLC 2026: Planted Contours and Changing Routes into Depth

Dense foliage, planted wood ridges and a low central route create different senses of distance in this four-work selection. The photographs are particularly rewarding when viewed through changes in leaf shape and planting height. They offer a present-season comparison with an archive that once described both graceful composition and more contemporary experimentation.
Thailand at IAPLC 2026: Surface Colour, Green Arches and Open Rockwork

Three Thai aquariums in the published Top 300 present contrasting visual priorities. MAGIC LEAVES makes the water surface a signature; another work carries a route beneath planted arches; a third exposes rock peaks against rounded greenery. This small group gives a useful reason to look beyond the first shared award photograph.
Indonesia at IAPLC 2026: Forest Craft Through Four Different Frames

The four Indonesian works published at ranks 1–300 offer a compact comparison. A coloured surface canopy, a dominant trunk, a dense grove and a wood-and-rock opening all reward close attention. The small group makes it possible to examine every represented work in this range, while keeping the conclusions specific to this season and cutoff.
Malaysia at IAPLC 2026: Wood, Plant Texture and the Visual Role of Fish

A bright gap between broad wood layers, a fine-leaved canopy and a conspicuous individual fish offer three different entrances to this Malaysian selection. The photographs invite attention to the space inhabited by fish as well as the hardscape around it. They also show why a creator’s reputation and a new aquarium’s visual decisions should be discussed separately.
Brazil at IAPLC 2026: Rock Landscapes and Wood Beyond the Familiar Label

Enchanted Hills offers an immediately recognisable rock valley, with coloured planting and fish in bright water. Three other selected Brazilian photographs build their scenes around substantial wood. Seeing them together is a useful way to revisit a familiar label without asking individual creators to fit a single national recipe.
Japan at IAPLC 2026: Nature Aquarium and Many Contemporary Visions

A pale path through hanging roots and a bright interval between exposed rocks can both make an aquarium feel spacious. Japan’s 2026 selection is rewarding because it places these different approaches beside richly planted foregrounds and coloured slopes. Six photographs offer a practical way to discuss variety within a familiar Nature Aquarium heritage.
China at IAPLC 2026: How Layered Wood Creates Convincing Depth

The Grand Prize photograph gives this study an obvious first stop, but the comparison becomes richer when it reaches beyond the winner. Six selected aquariums show different ways of framing light with wood: unequal trunks, fine leaf curtains, successive arches and repeated vertical roots. Their interest lies in how each arrangement keeps a densely constructed scene readable.
Vietnam at IAPLC 2026: Wood, Stone and a Broader Design Identity

Vietnam’s two leading 2026 awards both invite us into wooded environments. That is an interesting starting point for revisiting an archive which once associated the country strongly with stone. The most useful reading is not that one material has defeated the other. Six selected photographs show several ways of organising planted ground, open water and the route into a scene.
CIAC 2026 Official Results Update: Rankings Extend to 119

The CIAC 2026 Aquascaping Category results have received an official update. A results sheet distributed by the organising committee on 14 October lists ranks 14–119, extending the ranking information available beyond the image cards previously covered by AquaLibs.
