Dutch aquascape guide: rules, plants and how to build one

01

What is a Dutch aquascape?

The Dutch style developed in the Netherlands long before the term aquascaping existed, with hobbyists growing stem plants in carefully composed groups. Dutch aquarium clubs still run contests judged against detailed criteria such as plant health, color and texture contrast, composition and the fish chosen. Where the Iwagumi and Nature styles imitate landscapes, the Dutch aquascape is closer to a formal flower border: the plants themselves are the subject.

That means almost no visible hardscape. Rocks or wood, if used at all, are hidden behind or among the plants. Every square inch of the scene is foliage, so plant knowledge and pruning skill matter more than in any other style.

02

Dutch aquascape rules

The rules are guidelines from the contest tradition, not laws, but following them is what gives a Dutch style aquarium its recognizable look.

• Plants cover most of the substrate (often cited as 70–80% or more); bare sand only in streets and gaps
• About one plant species per 4 in (10 cm) of front length, so a 48 in (120 cm) tank holds roughly a dozen species
• Each species grows in its own group; avoid repeating the same plant in several places
• Neighboring groups contrast in color, height and leaf shape: a fine-leaved green next to a broad red, for example
• Plants rise in terraces from front to back, so the layout shows depth
• One or more "streets": rows of low plants that run diagonally toward the back
• Focal points placed off-center, ideally around the thirds of the tank, often with a red group
• Hardscape hidden or absent

Best plants for a Dutch style aquarium

Stem plants are the backbone because they can be trimmed into dense bushes and replanted to shape a group. Mix fine and broad leaves, and greens with reds. A few rosette plants such as the Amazon sword add structure, and low plants form the foreground and the streets. Many of them need root feeding, so plan aquarium fertilizer from the start.

Equipment for a Dutch aquascape

Depth is your friend. A tank with at least 18 in (45 cm) front-to-back depth gives room for terraces; a 75 gallon (280 L) or larger standard tank works well, while a 20 gallon long (75 L) suits a small first attempt. Because dozens of stem plants grow at once, the system needs to supply a lot of light, carbon and nutrients.

• Light: a strong, full-spectrum planted-tank LED that reaches the back of a deep tank; compare models in our aquarium light reviews
• CO2: a pressurized CO2 system is close to essential; see our guide to aquarium CO2 for target levels
• Substrate: a nutrient-rich planted substrate or plain gravel with root tabs under swords and crypts
• Filtration: a canister filter with even flow, so no corner stagnates behind dense plants
• Tools: long straight and curved scissors, long tweezers, a siphon for clippings

How to set up a Dutch aquascape step by step

Build the composition in one go rather than adding species over months. A fully planted tank uses nutrients from day one and leaves algae little room.

1. Draw the layout from above: mark streets, terraces and where each species will sit, with contrast between neighbors
2. Add substrate sloping from about 2 in (5 cm) at the front to 4 in (10 cm) or more at the back
3. Plant densely from day one: stems in bunches of single cuttings spaced about 1 in (2–3 cm) apart, lower leaves stripped
4. Plant the streets and foreground last, so you do not trample them
5. Fill slowly, start CO2 and fertilizing, and keep the light at 6 hours, rising to 7–8 hours over the first month
6. Change 30–50% of the water weekly during the first month to keep organics low while the tank cycles
7. Do the first shaping trim after 2–3 weeks, once the stems have rooted

06

Fish for a Dutch aquascape

The plants are the stars, so choose fish that move as a group and contrast with the foliage. Schools of rummy-nose tetras are a classic choice because they swim tight and show off red. Cardinal tetras and harlequin rasboras work too. Add otocinclus and Amano shrimp to graze algae from leaves. Avoid plant eaters such as silver dollars and goldfish, and large diggers that uproot stems.

07

Maintenance: trimming and replanting

A Dutch aquascape is shaped every week. Fast stems are trimmed to keep each group’s height and outline; when the lower stems become bare, cut the healthy tops, replant them and discard the old bases. Remove yellowing leaves, siphon clippings and keep 30–50% weekly water changes to export the excess nutrients from heavy fertilizing.

Check plants for deficiency signs each week: pale new leaves often point to iron, holes in older leaves to potassium. Adjust fertilizing gradually rather than doubling doses.

08

Common Dutch aquascape mistakes

Most failures come from too little contrast or too little maintenance rather than from bad plant choices.

• Too many species, which turns the garden into a patchwork
• Groups of similar greens next to each other, so nothing stands out
• Stems left to grow into the surface, shading the lower terraces
• Not enough CO2 for the plant mass, leading to black beard algae on slow leaves
• Shallow tanks, where terraces get crushed into one line
• Visible hardscape, which breaks the style
