Planted tanks
A great planted tank is built in layers. Put the right plants in the right zone — foreground, midground, background, floating, and epiphytes attached to hardscape — and your scape gains depth, your fish get cover, and everything grows the way it should.
The five zones
Where to Place Aquarium Plants
- Foreground (front)
Low carpeting plants that keep the open view. Easy picks: dwarf sagittaria, micro sword, Monte Carlo, or moss.
Keeps the front low so you can see into the tank. - Midground (middle)
Bushy, medium-height plants that bridge front and back. Easy picks: Cryptocoryne, Anubias, dwarf hairgrass clumps.
Adds body and hides the base of taller stems. - Background (back)
Tall, fast-growing stems that form a lush wall. Easy picks: Vallisneria, Amazon sword, Rotala, Hygrophila.
Creates depth and hides equipment. - Floating
Plants that drift on the surface. Easy picks: frogbit, red root floaters, duckweed (careful — it spreads fast).
Shades the tank, soaks up nutrients, and calms shy fish. - Epiphytes (on hardscape)
Plants that attach to wood or rock instead of substrate. Easy picks: Anubias, Java fern, Bucephalandra.
Don’t bury their rhizome — tie or glue it on, or it rots. - Carpet (advanced)
Dense low carpets like dwarf baby tears usually want more light and CO2.
Skip these until you’ve grown easier plants first.

Common Placement Mistakes
- Don’t bury epiphyte rhizomes (Anubias, Java fern) in the substrate — they rot. Attach them to wood or rock.
- Don’t put tall plants at the front — they block the view and shade everything behind.
- Don’t let floating plants cover the whole surface — they’ll starve plants below of light and lower gas exchange.
- Don’t plant a carpet under low light — it’ll grow leggy or melt. Match plants to your light.
Plant Placement FAQ
What are epiphyte plants?
Epiphytes are plants that grow attached to surfaces rather than rooted in substrate — like Anubias, Java fern and Bucephalandra. Tie or glue their rhizome to wood or rock; burying it causes rot.
Are floating plants good or bad?
Good in moderation — they shade the tank, absorb excess nutrients (helping with algae) and make shy fish feel safe. Just thin them regularly so they don’t cover the whole surface.
Where do I put Anubias and Java fern?
Both are epiphytes — attach them to driftwood or rock in the mid or background. They’re hardy, low-light, and perfect for beginners. Never bury the rhizome.
Where each plant type belongs
Plant placement is mostly about growth habit. If the roots, rhizome, and light needs are in the right place, the tank looks better and the plants struggle less.
- Foreground plants need short growth and easy trimming access.
- Midground plants should soften hardscape without blocking the whole tank.
- Background plants can grow tall and hide equipment, but they need room to spread.
- Epiphytes belong attached to rock or wood with the rhizome exposed.
- Floating plants belong where they will not shade slow plants too heavily or clog filter flow.
Think in zones before you buy. A plant that fits the right zone is much easier to keep than one you have to constantly fight.
Plant placement mistakes to avoid
Do not bury rhizome plants. Anubias, java fern, and bucephalandra should be attached to rock or wood with the rhizome exposed. If the rhizome is buried under substrate, the plant can rot even though the leaves looked healthy when you bought it.
Do not put heavy root feeders where the substrate is too shallow. Amazon swords and many crypts need room for roots plus nutrients near those roots. If they are planted in a thin layer of inert gravel with no tabs, they may survive but never really build momentum.
Do not let floating plants shade everything by accident. Floaters are excellent nutrient sponges, but they can block light from slower plants below. Thin them regularly and keep open areas where light can reach foreground and midground plants.
Quick placement review
After planting, review the tank from the fish’s point of view. There should be open swimming space, shaded retreats, grazing surfaces, and enough room to clean around the layout. If a plant blocks flow, shades the wrong area, or traps debris where you cannot reach it, adjust the placement before the roots settle too deeply. Small changes early prevent bigger maintenance problems later.
