Aquascaping is the art of arranging aquatic plants, rocks, driftwood, and substrate to create beautiful, natural-looking underwater landscapes. It's a hobby within a hobby — combining fishkeeping with elements of gardening, landscape design, and fine art.

There are three main aquascaping styles:

Nature Aquarium — pioneered by Takashi Amano, this style emulates natural landscapes using the golden ratio for composition. It typically features a main focal point (usually a rock formation or single large piece of driftwood) with plants creating depth and perspective.

Iwagumi — a sub-style of nature aquarium focused exclusively on rock (Iwagumi means 'rock formation'). Minimalist and meditative, often featuring low carpet plants and a single school of small fish.

Dutch Style — a European tradition that emphasizes plant diversity, color contrast, and dense planting in rows and terraced groups. More structured than nature aquarium, with an almost garden-like precision.

Key principles: Rule of thirds for composition, contrast between foreground/midground/background plants, proper lighting spectrum and duration (8-10 hours), CO2 injection for plant growth, and a nutrient-rich substrate capped with fine gravel or sand.

Beginner-friendly plants: Java moss, Anubias, Cryptocorynes, Amazon swords, and Vallisneria are excellent starting points that don't require CO2 injection.
