Aquascaping 101: 3 Easy Layouts for Your First Planted Tank

The dream of a lush, underwater jungle teeming with vibrant fish is what draws many of us into the world of aquariums. But venture online, and you’re bombarded with breathtaking, complex creations that seem more like submerged mountain ranges than fish tanks. It can be intimidating, leaving you to wonder if creating a beautiful planted tank is out of reach.

The truth is, it’s not.

Welcome to the wonderful world of aquascaping—the art of arranging aquatic plants, rocks, stones, and driftwood in an aesthetically pleasing manner within an aquarium. Like any art form, it’s built on a few simple principles that anyone can learn. This guide is your first step. We’ll break down the fundamental rules of aquarium design, introduce you to beginner-friendly materials, and then walk you through three stunning yet simple beginner aquascape ideas to help you create your first easy planted tank.

The Basic Principles: Your Artistic Foundation.

Before we place a single rock, let’s understand the “why” behind beautiful designs. You don’t need a degree in art history, just a grasp of a few key concepts that trick the eye into seeing depth and harmony.

The Rule of Thirds.

This is the most important principle in aquascaping. Imagine your tank is divided into a 3×3 grid, like a tic-tac-toe board. The Rule of Thirds suggests that the most powerful points of interest in your design should be placed along these lines or, even better, at their intersections. Instead of placing a large, impressive piece of driftwood right in the center, positioning it on one of the vertical third-lines creates a more dynamic and natural-looking scene.

Creating Depth: Foreground, Midground, Background.

A flat-looking aquarium is a common beginner mistake. To create a sense of depth and make your tank look larger than it is, think in three layers:

• Foreground: The front of the tank. Use low-growing, “carpeting” plants or fine sand here.
• Midground: The middle section. This is where you place your focal points—interesting rocks or driftwood—accented with medium-sized plants.
• Background: The back of the tank. Use tall, fast-growing stem plants to hide equipment and create a lush backdrop.

A simple trick to enhance depth is to slope your substrate. Make it shallow at the front and much deeper at the back. This immediately creates a forced perspective, making the tank feel more expansive.

Focal Points and Negative Space.

Your aquascape should have a clear focal point—one dominant rock, an intricate piece of wood, or a dense cluster of colourful plants that draws the eye. The rest of the scape should support this point. Equally important is negative space—the empty areas. Open water for fish to swim in and clear sandy patches provide visual relief and make the planted areas pop.

Your Aquascaping Palette: Easy & Forgiving Materials.

For your first tank, we’ll stick to common, hardy, and readily available materials.

Hardscape (The “Bones”).

• Driftwood: Spiderwood is fantastic for beginners, with many fine branches creating instant complexity. Mopani wood is a heavier, two-toned wood that sinks easily. Pro-tip: Boil your driftwood before use to help it sink and to release some tannins, which can turn your water a tea-like colour.
• Rocks: Dragon Stone (Ohko Stone) is lightweight, porous, and has incredible texture. Seiryu Stone offers beautiful colour contrast with deep grey tones and white veins. Important: Avoid rocks with sharp edges for delicate fish, and always test unknown rocks with a few drops of vinegar. If it fizzes, it’s not inert and will raise your water’s pH.

Plants (The “Life”).

Choosing the right plants is crucial for an easy planted tank. The following are hardy, low-light tolerant, and don’t require CO₂ injection to thrive.

• Foreground Plants:
  • Dwarf Sagittaria ($Sagittaria \\textit{subulata}$): Looks like a short, green grass and spreads via runners to create a lawn effect.
  • Marsilea Hirsuta: A very easy “clover-like” carpeting plant that stays low to the ground.
• Midground Plants:
  • Anubias Nana ($Anubias \textit{barteri}$ var. nana): The king of beginner plants. It’s nearly indestructible with thick, dark green leaves. Crucial: Its rhizome (the thick, horizontal stem) must NOT be buried. Attach it to rocks or driftwood with super glue or thread.
  • Java Fern ($Microsorum \\textit{pteropus}$): Similar to Anubias, this plant’s rhizome must also be attached to the hardscape. Its long, textured leaves provide beautiful contrast.
• Background Plants:
  • Vallisneria ($Vallisneria \\textit{spiralis}$): A tall, grass-like plant that grows quickly to the surface, creating a beautiful curtain effect at the back of your tank.
  • Amazon Sword ($Echinodorus \\textit{bleheri}$): A classic background plant with large, broad leaves. It’s a heavy root feeder, so place a root tab in the substrate beneath it.

Idea Gallery: 3 Easy Layouts for Your First Aquascape.

Here are three achievable designs that use the principles and materials we’ve discussed.

Layout 1: The Island (Central Mound).

This classic design is simple, effective, and leaves plenty of open swimming space for your fish. It’s a perfect first step into the world of aquarium design.

• Concept: A single, central structure of rock and/or wood that rises from the substrate, with plants arranged on and around it. The sides of the aquarium are left open.
• Materials Needed:
  • Hardscape: One captivating piece of Spiderwood, or a cluster of 3-5 medium-sized Dragon Stones.
  • Plants: Anubias Nana, Java Fern, Dwarf Sagittaria, and Vallisneria.
  • Substrate: Aqua soil or inert sand/gravel.
• Step-by-Step Guide:
  1. Create a mound of substrate in the center of your tank, sloping it down towards the front and side glass.
  2. Place your main hardscape piece (the driftwood or largest rock) slightly off-center on the mound, following the Rule of Thirds. Arrange the smaller rocks around it to create a stable, natural-looking base.
  3. Attach the Anubias Nana and Java Fern to the mid-level sections of your hardscape using super glue gel or fishing line.
  4. Plant the tall Vallisneria behind the hardscape to create the background.
  5. Plant the Dwarf Sagittaria around the base of the island, which will eventually spread to form a lush foreground carpet.
• The Final Vision: A beautiful, self-contained island of life that your fish can swim around, with clear lines of sight from every angle.

Layout 2: The Valley (Concave Layout).

This layout is a masterclass in creating depth. By building up the sides and leaving the middle open, you create an inviting path that draws the eye into the tank.

• Concept: The hardscape and taller plants are concentrated on the left and right thirds of the tank, sloping down to a low, open area in the center.
• Materials Needed:
  • Hardscape: A good number of Seiryu Stones or small pieces of driftwood (6-10 pieces of varying sizes).
  • Plants: Amazon Sword, Cryptocoryne Wendtii (another great midground plant), Marsilea Hirsuta.
  • Substrate: Dark aqua soil for the planted sides and a contrasting light-coloured sand for the central path.
• Step-by-Step Guide:
  1. Bank your aqua soil high on the back-left and back-right corners of the tank, sloping it steeply down towards the center-front.
  2. Create your “valley path” by pouring the light-coloured sand in the central, low-lying area. Use small rocks as a barrier to keep the soil and sand separated.
  3. Arrange your main stones or driftwood on the high slopes on either side. Point some of the wood or the “grain” of the rocks towards the back to enhance the sense of depth.
  4. Plant your tall Amazon Swords in the back corners, on the highest points of the substrate.
  5. Fill in the midground on the slopes with Cryptocoryne Wendtii.
  6. Plant the Marsilea Hirsuta at the edges of the soil where it meets the sand path. It will slowly creep into the valley.
• The Final Vision: A dramatic underwater landscape with two lush banks flanking a serene, sandy riverbed, giving an incredible sense of scale.

Layout 3: The Triangle (Side Slope).

Also known as a triangular or slope layout, this asymmetrical design is incredibly dynamic and visually powerful. It’s simple to execute but looks very professional.

• Concept: The aquascape is heavily weighted to one side of the tank, with the height and visual mass tapering down to the opposite corner.
• Materials Needed:
  • Hardscape: A large, branching piece of driftwood and a few supporting rocks.
  • Plants: Rotala Rotundifolia (an easy, colourful stem plant), Java Fern, Anubias Nana, and Dwarf Sagittaria.
  • Substrate: Aqua soil.
• Step-by-Step Guide:
  1. Choose one back corner of your tank to be the high point. Pile your substrate high in this corner, creating a steady slope down to the opposite front corner, which will have very little substrate.
  2. Anchor your main piece of driftwood in the high corner, with its branches reaching out across the tank towards the low point. Use rocks around its base to secure it firmly.
  3. Plant the fast-growing Rotala Rotundifolia densely in the high back corner, behind the driftwood.
  4. Attach Java Fern and Anubias Nana along the branches and base of the driftwood, following the downward slope.
  5. Plant the Dwarf Sagittaria in the low-lying corner and midground, leaving the very front of the low side empty for a clean look.
• The Final Vision: A powerful, flowing design that guides the eye from the dense, high corner across the open water to the low corner. It provides a perfect balance of dense shelter and open swimming space.

Final Thoughts: Just Add Water (and Patience).

Once your layout is complete, the journey has just begun. You’ll need to carefully fill the tank, install your filter and heater, and most importantly, perform a “fishless cycle” to build up beneficial bacteria before adding any livestock.

Aquascaping is a rewarding, living art form. Don’t be afraid to experiment. These beginner aquascape ideas are not rigid rules but starting points for your creativity. Your first easy planted tank is a canvas for learning what you love and developing your own style. Grab some rocks, find a piece of wood that speaks to you, and start building your own underwater paradise. The world of aquarium design awaits.
