Iwagumi aquascape (90 L)

Japanese minimalist style: 3–5 stones, carpet plants, one small school.

Iwagumi aquascape (90 L) — aquarium setup with fish, plants and equipment (90 L)

A style created by Takashi Amano. Key rules: an odd number of stones, one 'oyaishi' (main) and the rest 'soeishi'.

Chili rasboras are the only school — to preserve visual purity. They glow like red dots against the green.

Tips & gotchas

  • Stones — odd count, asymmetric layout. Buy 5–7, place 3–5.
  • Carpet plants need CO₂ + strong light. Without them, you get algae.
  • First month — daily parameter checks; active substrate releases ammonia.
  • Minimal decor. Cleanliness is the rule.
