Aquascaping styles: Dutch, Nature/Iwagumi and jungle compared
Three named styles cover most of what you'll see described as "aquascaping": Dutch (dense, terraced rows of contrasting plants, no rocks or wood), Nature Aquarium and its Iwagumi variant (Japanese-garden-influenced, built around carefully placed stone or wood as the visual anchor), and jungle style (deliberately dense, mixed and lower-maintenance). They're not difficulty tiers — they're different design goals with different weekly workloads, and picking one that matches how much trimming time you actually want to commit to matters more than picking the "best-looking" one from a photo.
Before you plan a layout
This guide helps if…
You've got the basics of a planted tank sorted (or are about to set one up) and want to plan its visual layout intentionally, rather than adding plants ad hoc as you go.
Look elsewhere first if…
You haven't decided which plants to buy yet — see our best beginner aquarium plants comparison — or you're setting up the tank itself for the first time, covered in our starting a planted aquarium guide. This page assumes those decisions are already underway.
Worth knowing: these are established hobby conventions and competition categories, not fixed rules you have to follow exactly. Plenty of successful tanks borrow elements from more than one style rather than adhering strictly to any single one.
Dutch style
Dutch-style aquascaping originated in the Netherlands in the 1930s and was later codified into a judged standard by the Dutch aquarium and terrarium keeping society (NBAT), making it one of the oldest formalised layouts in the hobby[1]. The defining feature is what it deliberately leaves out: no rocks, no driftwood, no hardscape at all — the entire composition is built from plants.
Plants are arranged in "streets": rows of a single species running from front to back, typically starting wider at the front and narrowing toward the rear to create an exaggerated sense of depth[1]. Multiple streets sit side by side, using contrasting leaf colour, shape and texture between neighbouring streets rather than relying on any focal stone or wood piece. A commonly cited guideline is that roughly 70% or more of the substrate should be planted, leaving little open ground[1].
The trade-off is maintenance. Because the entire visual effect depends on crisp, well-defined streets, Dutch tanks typically need frequent, disciplined trimming to stop faster-growing species overrunning slower neighbours and blurring the rows together — this is a genuinely higher weekly time commitment than the other two styles covered here, not a one-off setup cost.
Nature Aquarium and Iwagumi
Nature Aquarium is a style developed by the Japanese aquarist Takashi Amano, who founded the equipment and design company ADA (Aqua Design Amano) in 1982 and later documented the approach across his influential "Nature Aquarium World" book series[2]. It draws on Japanese garden design and the aesthetic idea of wabi-sabi — finding beauty in asymmetry, negative space and a composition that reads as discovered rather than deliberately arranged[2]. Unlike Dutch style, hardscape (stone or driftwood) plays the leading visual role, with plants and fish arranged around it rather than replacing it.
Iwagumi is the best-known stone-focused variant within Nature Aquarium, and the one most beginners mean when they say they want to try "Amano-style" scaping. It follows a specific, named stone hierarchy[3]:
- Oyaishi (main stone) — the largest, focal stone the whole layout is built around, conventionally around two-thirds of the tank's height and placed off-centre rather than in the middle.
- Fukuishi (secondary stone) — a visual counterpoint placed to one side of the Oyaishi, usually smaller.
- Soeishi (supporting stone) — reinforces the main stone's visual weight and direction.
- Suteishi (accent stones) — smaller finishing stones, sometimes partly hidden by plant growth as the scape matures.
Two further conventions are widely reported as close to universal in Iwagumi specifically: stone counts are kept odd (three, five, seven), since an even number tends to read as symmetrical and static rather than natural[3]; and only one type of stone is used throughout the layout, with driftwood typically left out entirely[3]. Planting is usually minimal and low-growing (commonly a carpeting foreground plant) so the stone arrangement itself stays the focus.
Because Iwagumi in particular offers very little cover — no wood, dense mid-ground growth or floating plants to hide in — it's worth thinking about livestock choice alongside the visual plan, not after it. Small, calm, open-swimming shoaling fish are the conventional stocking choice for this style; territorial, shy or cover-seeking species are a poor match for a layout with almost nowhere to retreat to. See our choosing tank mates guide for the general temperament and compatibility framework behind a stocking decision like this.
Jungle style
Jungle style takes roughly the opposite approach to Iwagumi: dense, deliberately mixed planting across a wide range of species, heights and leaf textures, aiming for a lived-in, naturally overgrown look rather than a controlled composition[4]. Tall background growth, bold mid-ground species and surface or floating cover are typically combined so the layout reads as full from most angles rather than built around a single focal point.
It's commonly described as lower-maintenance than Dutch style, but that's a relative claim, not "no maintenance": once a jungle tank is established, dense growth genuinely needs less frequent shaping than Dutch streets do, but dead or obstructive growth still needs removing periodically, and a jungle tank left completely untouched can still become an overgrown, light-blocking mess for the fish underneath it[4]. Because it's forgiving of mixed species and doesn't depend on crisp lines the way Dutch style does, it's often a more realistic starting point for a first attempt at deliberate aquascaping.
Comparison at a glance
| Style | Hardscape | Plant variety | Trimming workload |
|---|---|---|---|
| Dutch | None | High — many species in defined streets | High — frequent, disciplined trimming |
| Nature/Iwagumi | Central to the design | Low (Iwagumi) to moderate (broader Nature Aquarium) | Moderate — precision shaping around the hardscape |
| Jungle | Optional, secondary | High — deliberately mixed | Lower once established, not zero |
Which style actually suits you
Rather than choosing on looks alone, it's worth being honest about two things: how much weekly trimming time you actually want to commit to, and what you're planning to stock. If you want minimal ongoing shaping work and don't mind a less structured look, jungle style is the most forgiving starting point. If you want the crisp, layered look of a Dutch tank, be realistic that it needs consistent weekly attention to stay looking that way — it isn't a one-off setup. If you're drawn to Iwagumi specifically, plan your fish and shrimp stocking around the lack of cover from the start, not as an afterthought once the stones are already placed.
Common mistakes
- Adding driftwood or a second stone type to an Iwagumi layout, which breaks the single-material convention the style is built around.
- Centring the main stone in an Iwagumi instead of placing it off-centre — a symmetrical arrangement tends to look static rather than natural.
- Underestimating Dutch style's trimming workload and letting streets blur together after a few weeks of neglect.
- Stocking cover-seeking or territorial fish in a sparse Iwagumi with nowhere to retreat to.
- Treating jungle style as maintenance-free and letting dead growth accumulate and block light long-term.
Frequently asked questions
What's the easiest aquascaping style for a beginner?
Jungle style is generally the most forgiving starting point: it tolerates mixed species and imperfect trimming without the composition falling apart, unlike Dutch style's precise streets or Iwagumi's exposed, symmetry-sensitive stone arrangement.
Do I need CO2 injection for these styles?
Not necessarily. All three styles can be built with low-tech, low-light plant choices — see our beginner plant comparison for species that don't need CO2. That said, denser Dutch layouts and some higher-light Nature Aquarium scapes are commonly run with CO2 injection to support faster, more controlled growth. See our CO2 guide for the trade-offs.
Can I mix elements of different styles?
Yes — these are established conventions, not rules enforced anywhere outside formal judged competitions. Plenty of tanks combine a Nature-Aquarium-style hardscape focal point with a more relaxed, jungle-style planting density around it.
How AquaPulse can help
A more heavily planted, higher-light layout — whichever style you choose — generally means more to keep track of: trimming schedules, fertiliser dosing, and how your water parameters respond as the tank fills in. AquaPulse doesn't identify a plant species or judge a layout, but it can help you log maintenance tasks and water-test results over time, so you've got an actual record to check against rather than relying on memory as the tank matures.
Get AquaPulse on the App Store or Google Play to try it, or see the Water Check feature page for more detail.

What we deliberately left out: biotope aquascaping (recreating a specific real-world habitat) as a fourth full section, since it's a substantially different goal — ecological accuracy rather than aesthetic composition — that deserves its own treatment rather than a brief mention here; and a specific numeric CO2 or light-intensity recommendation per style, since actual requirements depend heavily on the specific plant species chosen within each style, not the style itself.
