Live Aquarium Plants
Live plants are the foundation of a natural-looking aquarium. They absorb nitrates, produce oxygen, and provide shelter for fish and fry. Beginner-friendly species include Java Fern (attaches to wood and rocks), Anubias (slow-growing and nearly indestructible), Amazon Sword (striking background plant), and Java Moss (versatile carpet or accent plant).
Most beginner plants thrive in standard aquarium lighting without CO2 injection. Use a nutrient-rich substrate or root tabs for rooted species.
Rocks, Wood, and Hardscape
Natural hardscape materials create structure and visual interest. Popular choices in the UK include Seiryu stone (dramatic grey rock), Dragon stone (textured orange-brown), Mopani wood (dense and sinks immediately), and Spider wood (branching, creates a tree-like effect).
Always ensure rocks and wood are aquarium-safe. Avoid anything that could alter water chemistry unless you specifically need that effect (e.g., limestone raises pH).
Artificial Decorations
Artificial plants and ornaments are low-maintenance alternatives that never need trimming, fertilising, or specific lighting. Modern silk plants look remarkably realistic and are softer than plastic versions, making them safer for fish with delicate fins like bettas.
Popular ornaments include caves, castles, sunken ships, and themed pieces. Ensure any decoration is specifically designed for aquarium use — non-aquarium items may leach harmful chemicals.

Aquarium Decor FAQ
Do fish need decorations in their tank?
Yes. Decorations provide essential hiding spots, territorial boundaries, and enrichment. Fish in bare tanks often show signs of stress and poor colouring.
Are live plants hard to maintain?
Not at all. Many beginner species like Java Fern and Anubias require minimal care — just standard lighting and occasional liquid fertiliser. They actually make maintenance easier by absorbing waste products.
Can I use rocks from my garden?
It is not recommended. Garden rocks may contain minerals that alter water chemistry or contaminants that harm fish. Use aquarium-specific rocks from a reputable supplier.
