Dutch-Style Aquascaping: A Guide to the Plant-Only Layout
The rules behind the Dutch style: dense terraced planting, no hardscape, 'streets' for depth, and the one-species-per-10cm guideline.
What defines a Dutch aquascape
Practical Fishkeeping describes the Dutch style as a formal, garden-like approach that uses neat rows and groups of plants to please the eye. Its two hallmarks are the complete absence of hardscape (no feature rocks or wood) and an absolute mass of dense planting, often built up in terraces from front to back, plus a thick, vibrant carpet. The style's guidelines were codified by the NBAT, the Dutch Society for Aquarists, from 1956.
Streets and terraces
The most recognisable Dutch device is the 'street': a corridor of a single plant (Lobelia and Staurogyne are classics) running back into the layout to create a strong sense of depth. Plants are stacked in terraces so each group is visible above the one in front.

Contrast and plant choice
Dutch tanks are built mostly from stem plants chosen for contrasting colours, textures and leaf sizes. Placing a fine-leaved green next to a broad red, and keeping each group distinct, is what produces the style's rich contrast and visual rhythm.
Keys to success
- Plant densely from day one — bare substrate is not the Dutch look.
- Maximise contrast between neighbouring groups (colour, leaf shape, height).
- Use streets and terracing to build depth.
- Provide strong light, CO2 and fertilisation to sustain the plant mass.
