An aquascape plant density planner tells you how many foreground, midground, and background plants to buy based on your tank size and chosen aquascape style. Nature Aquariums use focused groups with open space; Dutch aquascapes pack every centimeter with regimented rows; jungle tanks allow natural density without strict rules.

How to Plan Aquascape Plant Density
Plant density determines whether your aquascape looks intentional or haphazard. The right number of plants covers substrate, discourages algae, and achieves the visual style you're after — whether that's the minimalist tension of a Nature Aquarium or the lush fullness of a jungle tank.
Step 1: Choose Your Style
Nature Aquarium uses negative space purposefully — 30–40% of the scape should be open sand or rock. Dutch style covers every square centimeter with color-coordinated plant groups. Jungle style layers plants in overlapping zones without strict rules, prioritizing lush coverage over structure.
Step 2: Understand Foreground vs Background
Foreground plants are low-growing carpets (Hemianthus, Monte Carlo, Glossostigma). Midground plants are medium-height accents (Cryptocoryne, Anubias, Bucephalandra). Background plants are tall stem plants that fill the back (Rotala, Ludwigia, Hygrophila). The planner estimates realistic quantities for each zone.
Step 3: Buy in Tissue Culture or Bunches
Tissue culture cups typically contain 30–60 small plantlets each. Stem plant bunches contain 5–10 stems. Factor this into your purchase — a single tissue culture cup of HC Baby Tears might plant your entire foreground in a 60×30 cm tank if separated into individual stems.
Step 4: Allow for Growth
Stem plants grow fast — what looks sparse at planting fills in within 2–4 weeks. Carpeting plants spread laterally over 4–6 weeks. Plant at the recommended density rather than over-planting, which wastes money and requires immediate trimming.
FAQ
How many plants do I need for a planted tank?
A 60×30 cm Nature Aquarium typically uses 30–50 stem plants for the background, 10–20 midground rosettes, and 5–15 foreground carpeting plants. Dutch style uses more plants with strict row discipline. Low-tech jungles use fewer but larger specimens.
What is the difference between Nature and Dutch aquascape styles?
Nature Aquarium (Amano style) mimics natural landscapes with open negative space and grouped plants. Dutch style is a formal garden aesthetic with strict rows, contrasting colors, and high plant density. Jungle style is loose and natural with minimal structure.
How close should stem plants be planted?
Stem plants for backgrounds are typically planted 1–2 cm apart for dense coverage. Midground plants need 5–8 cm spacing. Foreground carpeting plants like Hemianthus callitrichoides (HC) are placed every 2–3 cm. Dutch style rows use 2–3 cm spacing within groups.
Is this calculator free?
Yes, completely free with no signup required.
Can I use this for nano tanks?
Yes. Enter any tank volume. For nano tanks under 30L, the planner adjusts to show realistic low counts — you can't fit 50 stem plants in a 10-liter cube.
What's a good foreground carpeting plant?
Popular carpeting plants include Hemianthus callitrichoides (HC/Baby Tears), Micranthemum tweediei (Monte Carlo), Marsilea hirsuta, and Glossostigma elatinoides. HC needs high light and CO2; Monte Carlo and Marsilea are easier for beginners.
