One Aquascaper, Two Stages: Five Journeys Across IAPLC and CIAC.

09 October 2026

596

Aquascaping results are usually read one competition at a time. Follow the author's name across IAPLC and CIAC, however, and a richer story comes into view: a double championship, two very different layouts in one season, or a striking work discovered through a second gallery.

One Aquascaper, Two Stages: Five Journeys Across IAPLC and CIAC.

With both competitions scheduled to reveal their 2026 results on October 10, this is a timely moment to look at the people who connect these two international stages. A familiar name in one results list can become an invitation to explore another part of that creator's work.

This feature follows five aquascapers whose published records include both contests: Josh Sim, Gang Zhao, Kawin Arponiam, Antonio Nikolic and Lich Do. The selection combines an important historical milestone with examples from 2024 and 2025, using archived photographs and linked AquaRank profiles.

Five creators, two competition records

Aquascaper	Country	Season compared	IAPLC result	CIAC result
Josh Sim	Malaysia	2017	World Rank 1 — Grand Prize	Rank 1 — Champion
Gang Zhao	China	2025	World Rank 2 — Gold Prize	Rank 2 — Runner-up
Kawin Arponiam	Thailand	2025	World Rank 178	Rank 7
Antonio Nikolic	Croatia	2025	World Rank 231	Rank 16
Lich Do	Vietnam	2024	World Rank 125	Rank 45

Each row pairs results from the same season. The CIAC 2024 and 2025 positions refer to the Aquascaping Group; the 2024 figure follows the final CIPS ranking.

These are separate competitions with separate fields and judging processes. The numbers identify each published finish; subtracting one from the other would not measure an improvement. The connection examined here is the creator, and the photographs show why that distinction matters.

1. Josh Sim: a double championship worth revisiting

Malaysia · IAPLC 2017, World Rank 1 · CIAC 2017, Rank 1

Josh Sim offers a powerful historical starting point. His Congo won the IAPLC 2017 Grand Prize, and CIPS also identified Congo as his championship-winning work when looking back on the inaugural 2017 contest.

The archived scene draws the eye through a dense network of wood and planting toward a bright opening. Large foreground structures establish scale, while smaller branches and fine foliage make the distance feel much deeper than the aquarium itself.

Its two titles make Congo a memorable example of recognition across competitions. The image also offers something more lasting than an award count: a composition that still rewards a careful look at how foreground detail, shadow and distance work together.

Open Josh Sim's AquaRank profile to follow the wider career around that season. For the work itself, explore the CIAC 2017 gallery and AquaLibs' feature on Congo.

2. Gang Zhao: matching finishes, contrasting landscapes

China · IAPLC 2025, World Rank 2 · CIAC 2025, Rank 2

Gang Zhao's 2025 results look remarkably symmetrical: second place at IAPLC and second place at CIAC. The photographs introduce a much less symmetrical—and more interesting—visual story.

The Pulse of Life — Gang Zhao, China — CIAC 2025, Rank 2, Runner-up. Archived contest photograph; the Chinese title is 生命的脉动.

The IAPLC image is organised around sweeping wood, moss-covered surfaces and a forest-like opening. The CIAC image presents a different composition, with rock ledges framing a bright passage. They demonstrate how following one author can lead us to contrasting approaches to structure and depth.

There is a useful viewing exercise here: follow the line that takes your eye into each scene. In one, wood creates much of that movement. In the other, the shape of the open space becomes especially prominent. Similar placements in the results do not make the works visually interchangeable.

Explore Gang Zhao on AquaRank to keep both records together, then open the IAPLC 2025 gallery and CIAC 2025 gallery for a closer look.

3. Kawin Arponiam: discovering Longevity through another stage

Thailand · IAPLC 2025, World Rank 178 · CIAC 2025, Rank 7

Kawin Arponiam's Longevity appears by that title in both archived contest images. Its published positions—178th at IAPLC and seventh at CIAC—show why browsing a second competition can change which works reach a reader's attention.

The wood remains the central attraction. A substantial trunk on the left and a web of exposed roots establish a sense of age and character. Plant cushions settle around those forms, allowing the hardscape to retain its bends, hollows and direction.

A reader who stops at IAPLC's leading hundred would miss this result. A reader exploring CIAC's leading ten would encounter it almost immediately. That difference in visibility is a good reason to follow creators across galleries, while allowing each result to retain its own context.

Visit Kawin Arponiam's AquaRank profile and the step-by-step feature on Longevity to continue from the finished images to more of the work behind them.

4. Antonio Nikolic: a sheltered world beyond the headline places

Croatia · IAPLC 2025, World Rank 231 · CIAC 2025, Rank 16

Antonio Nikolic's Dark provides another reason to keep exploring. The title is printed on both archived images, alongside World Rank 231 at IAPLC and 16th place at CIAC.

Dark — Antonio Nikolic, Croatia — IAPLC 2025, World Rank 231. Archived contest photograph.

Dark — Antonio Nikolic, Croatia — CIAC 2025, Rank 16. Archived contest photograph.

Heavy wood and green growth frame a shaded interior, where a group of pale fish becomes particularly noticeable. The contrast between shelter and open swimming space gives the scene a strong sense of an underwater habitat.

Look at the dark gaps beneath the branches as carefully as the planted surfaces. They help separate the layers and make the fish readable. This is the kind of detail that becomes easier to appreciate when an image is opened at full size rather than viewed as a small results thumbnail.

Follow Antonio Nikolic on AquaRank to explore the broader record. Dark is a rewarding entry point into a creator's work even when the first place we encounter his name is well down a ranking list.

5. Lich Do: two views of a Vietnamese creator's 2024 season

Vietnam · IAPLC 2024, World Rank 125 · CIAC 2024, Rank 45

Lich Do's 2024 record brings the feature back to the importance of reading the archive carefully. The IAPLC image is titled Ramble, while the CIAC image is titled Millennium. We retain those published titles and present the photographs under their respective contest records.

Ramble — Lich Do, Vietnam — IAPLC 2024, World Rank 125. Archived contest photograph.

Millennium — Lich Do, Vietnam — CIAC 2024, Rank 45 in the final Aquascaping Group results. Archived contest photograph.

Both views reward attention to the relationship between large wood forms and the space within them. The IAPLC photograph makes its blue fish particularly prominent against the green interior; the CIAC photograph shows fish spread across the middle water beneath a heavily framed canopy.

For readers following Vietnamese aquascaping, the pair offers a reason to explore beyond one annual list. It also illustrates how the title, photograph and contest label all contribute to a faithful account of an author's career.

Open Lich Do's AquaRank profile, then browse the IAPLC 2024 and CIAC 2024 galleries. The profile uses the name Do Lich; the contest images identify him as Lich Do.

Follow the creator, keep the context

These five examples offer several ways into the archive. Josh Sim provides a double championship. Gang Zhao connects matching positions with contrasting compositions. Kawin Arponiam and Antonio Nikolic show how a second gallery can bring a work into view. Lich Do reminds us to preserve the details attached to each record.

The ranking alone cannot explain why a work received a particular position. Establishing the reasons would require the relevant judging records and commentary. What readers can do immediately is explore the photographs, compare visible design decisions and follow the author's recorded history.

AquaRank brings those histories together through linked profiles and competition records. Start with an aquascape you admire, open its creator's profile, and choose another recorded work. That small step can turn one results announcement into a much longer discovery.

Two announcements, more creative journeys to discover

ADA has scheduled the IAPLC 2026 Top 100 photographs and ranking reveal for October 10 at 1:00 PM JST, with the complete ranking list to follow the livestream. The official CIAC schedule also lists October 10 for its results announcement, without specifying an hour on that page.

The examples in this article are completed historical results. The new lists will give us the evidence to see which authors appear across both competitions in 2026 and which works deserve a closer look.

When the results arrive, keep a name that interests you in mind as you explore the second gallery. The next discovery may be another approach by a familiar creator—or a creator you will want to follow for years.

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.
