Driftwood and hardscape for discus: 5 types + full preparation
Driftwood for discus — an advanced guide with 5 types (Malaysian, Mopani, Spider, Manzanita, Redmoor), step-by-step preparation (boiling, soaking), Golden Ratio layout rules and where to buy quality wood.
Quick summary
- 5 safe types: Malaysian (#1), Mopani, Spider wood, Manzanita, Redmoor/Savanna
- Never use: foraged DIY wood, conifers (resin), bamboo, submerged cork bark
- Mandatory prep: boil 30–60 min + soak 1–14 days until it sinks on its own
- For discus: hiding spots, antibacterial tannins, support for epiphytes, less stress
- Layout: Golden Ratio (focal point at 1/3), keep 40–50% of the footprint open
- Tannins lower pH gently and tint the water amber — beneficial, not a problem
In short
- 5 types safe for discus: Malaysian driftwood (#1 — dense, sinks on its own, releases tannins), Mopani wood (two-tone brown/tan), Spider wood (aesthetically branched), Manzanita (light, minimal), Redmoor / Savanna (European, accessible).
- NEVER use: foraged DIY forest wood, conifers (fir, pine, spruce), bamboo, submerged cork bark.
- Mandatory prep: boil 30–60 min + soak 1–14 days (until it sinks on its own).
- Function for discus: hiding spots for hierarchy, releases antibacterial tannins, support for epiphytes (Anubias, Java fern), reduces stress.
- Layout: Golden Ratio (focal point at 1/3, not the middle), open swimming zones over at least 40–50% of the footprint.
What you'll learn
Driftwood is the central element of the hardscape in a discus aquarium (Symphysodon) — in the wild, discus are adapted to habitats full of submerged roots and branches, hiding among the roots of fallen trees in calm water. This advanced guide shows you 5 safe driftwood types, the wood to avoid, step-by-step preparation (boiling, soaking, testing tannins), layout principles (Golden Ratio, visual triangle) and where to buy quality pieces.

Why driftwood matters for discus
| Benefit | Explanation |
|---|---|
| Hiding spots | Reduces stress, provides territories for the natural hierarchy |
| Tannin release | Slightly acidic water (pH 6.0–6.5), a documented antibacterial effect |
| Less aggression | Broken sightlines = less bullying between discus |
| Wild aesthetics | Recreates the natural habitat — a striking effect |
| Biofilm support | Food for L-plecos, cory and shrimp |
| Epiphyte support | Anubias, Java fern, Bucephalandra attach directly to the wood |
5 safe driftwood types for discus
1. Malaysian driftwood ⭐⭐⭐⭐⭐
The most popular for discus. Dense, dark wood that sinks on its own after a few days of prep.
| Feature | Detail |
|---|---|
| Color | Dark brown to black |
| Shape | Substantial, with natural grooves |
| Floats | NO — sinks in 1–3 days |
| Tannins | ⭐⭐⭐⭐ Lots (months–years) |
| Sizing | Medium piece ≈25–35 cm (10–14 in) |
Perfect for: Amazon biotope, tannin-focused discus tanks, beginners.
2. Mopani wood ⭐⭐⭐⭐⭐
Two colors on the same piece — light and dark brown, striking contrast.
| Feature | Detail |
|---|---|
| Color | Two-tone (cream + dark brown) |
| Shape | Substantial, often branched |
| Floats | Initially YES — needs 5–14 days of soaking |
| Tannins | ⭐⭐⭐⭐⭐ Very high initially, drops after 2–3 months |
Note: it releases far more tannins than Malaysian — you'll need more frequent water changes for the first 2–4 weeks (or accept "tea-colored" water — perfect for a biotope).
3. Spider wood (azalea roots) ⭐⭐⭐⭐⭐
The most "aquascaper-friendly" — impressive branched shapes, "Takashi Amano" style.
| Feature | Detail |
|---|---|
| Color | Light brown to cream |
| Shape | Branched, "spider-like" |
| Floats | YES — floats for 1–4 weeks, needs anchoring |
| Tannins | ⭐⭐ Low |
Perfect for: Nature Aquarium style, "forest" style, combinations with stones.
Downside: decays faster than Malaysian (2–4 years vs 5–10 years).
4. Manzanita ⭐⭐⭐⭐
Light, elegant wood, a favorite of premium aquascapers.
| Feature | Detail |
|---|---|
| Color | Light gray-brown |
| Shape | Branched, airy |
| Floats | YES initially — needs 7–14 days of soaking |
| Tannins | ⭐ Very low |
Good for: bright tanks, Iwagumi + wood style, minimalist aquascape.
5. Redmoor / Savanna wood ⭐⭐⭐⭐
European roots — sustainable, local, accessible prices.
| Feature | Detail |
|---|---|
| Color | Reddish-brown |
| Shape | Branched, natural |
| Floats | Initially YES — soak 5–10 days |
| Tannins | ⭐⭐⭐ Moderate |
| Origin | Europe (Poland, Germany, etc.) |
Bonus: widely available across European aquarium shops.
Wood to AVOID completely
| Wood type | Why |
|---|---|
| Foraged DIY forest wood | Risk of pesticides, parasites, fast rot, unknown pH |
| Conifers (fir, pine, spruce) | Resin is TOXIC to fish — never |
| Bamboo | Rots fast, releases problematic compounds |
| Submerged cork bark | OK for paludariums, not aquariums (breaks down) |
| Fresh green wood | Sap still active — releases unidentified compounds |
| Wood with visible mold | Spores that contaminate the aquarium |
| Lacquered / treated wood | Toxic chemicals |
Preparing driftwood — step by step
Step 1: Inspection
- Look for large holes, fragile pieces, an off smell
- Reject wood with mold or visible insects
- Make sure it isn't a conifer species
Step 2: Mechanical cleaning
- Stiff brush (NOT metal) + warm tap water
- NO detergent, soap or baking soda — toxic to fish
- Rinse thoroughly under running water
Step 3: Boiling (strongly recommended)
Why: kills bacteria, spores and parasite eggs + removes 50–70% of tannins + helps it sink.
| Wood size | Boiling time |
|---|---|
| Small (under 20 cm / 8 in) | 30 minutes |
| Medium (20–40 cm / 8–16 in) | 45–60 minutes |
| Large (40–60 cm / 16–24 in) | 60–90 minutes |
| Very large | Pour boiling water over it + prolonged soaking |
Tip: change the water 2–3 times if it stains heavily — a sign it's releasing lots of tannins.
Step 4: Soaking in cold water
1–14 days in a large bucket of water, changed daily:
| Wood type | Soak time |
|---|---|
| Malaysian, Mangrove | 1–3 days |
| Mopani | 5–14 days |
| Spider wood | 7–21 days or permanent anchoring |
| Manzanita | 7–14 days |
| Redmoor | 5–10 days |
Signs it's ready: it sinks without anchoring + the water stays nearly clear after 24h (minimal tannin release).
Step 5: Testing tannins (optional)
Put the wood in a bucket with 5L (≈1.3 US gal) of clean water for 48h. Assess the color:
- Nearly clear water = ready, you can add it to the tank
- Yellow water = OK, but expect "tea" water in the tank (perfect for a biotope)
- Dark brown water = soak another 5–7 days or boil again
Layout — aquascape principles
The Golden Ratio (1.618)
Don't place the wood in the center. Put the focal point at 1/3 of the width (left or right).
Example, 120 cm (47 in) tank: focal point at 40 cm or 80 cm — never at 60 cm (the middle).
The visual triangle
The dominant elements (main driftwood + accent) form an imaginary triangle — this creates visual stability.
Popular styles for discus
"Amazon Jungle" style (biotope)
- 1–2 large Malaysian pieces as the base
- 3–5 branched Spider wood pieces above

"Nature Aquarium" style (Amano)
- 1 dominant piece (Mopani or Manzanita)
- Branched Spider wood for depth
- A minimal carpet (Echinodorus tenellus)
- Bright tank, moderate plants
"Minimalist breeder" style
- Just 2–3 large vertical pieces
- No plants (or minimal Anubias)

Functional rules for discus
| Rule | Why |
|---|---|
| 40–50% open footprint | Room for mid-water swimming |
| Hiding spots at 2–3 levels | Subordinate discus have somewhere to retreat |
| NO enclosed canyons | Fry or adults can get trapped |
| NO sharp wood | Discus can scrape their flanks (sensitive mucus) |
| Keep the vertical column open | Discus swim mid-water — don't block it entirely |
Driftwood with attached plants
Plants that are NOT planted in the substrate — they attach to the wood:
| Plant | How to attach | Note |
|---|---|---|
| Anubias nana / barteri | Thread or super glue gel | The most popular |
| Microsorum pteropus (Java fern) | Thread | Tolerates 29°C / 84°F |
| Microsorum "Trident" | Thread | Aesthetic narrow leaves |
| Bucephalandra | Super glue gel | Limit ≈28°C / 82°F |
| Mosses (Java moss, Christmas moss) | Thread or mesh | Slow at 29°C / 84°F |
💡 The aquarium super glue gel method (cyanoacrylate) — put a drop on the plant's rhizome, press it onto the wood, it bonds instantly. 100% fish-safe once cured (5–10 seconds).
Maintenance
| Task | Frequency |
|---|---|
| White biofilm on new wood (2–4 weeks) | NORMAL — disappears on its own (or plecos/cory eat it) |
| Vacuum under and around the wood | Weekly |
| Clean the wood surface | Soft brush as needed, NO detergent |
| Replacement | Malaysian/Mopani: 5–10 years · Spider wood: 2–4 years |
| Signs it needs replacing | Goes soft, crumbles, smells rotten |
Common mistakes
❌ "I'll put the wood straight in, no boiling" — risk of bacteria, parasite eggs, rot in the tank, brown water for months.
❌ "I'll grab wood from the local riverbank" — risk of pesticides, rotten wood, fungi, unknown species. Only if you clearly identify the species (e.g. willow or birch dried 6+ months).
❌ "The wood floats, I'll weigh it with a stone for a day and that's it" — Spider wood floats for weeks. Anchor it with a stainless bolt under the substrate or super glue gel to a heavy base stone.
❌ "The water turned brown, I'll swap out the new wood" — brown water is BENEFICIAL. Antibacterial, gently acidifies the pH, recreates the Amazon. Only change it if you want clear water aesthetically (more water changes + temporary activated carbon).
❌ "I'll add 5 big driftwood pieces so it looks full" — an over-decorated tank = less swimming room for discus (large mid-water fish), dead zones where waste accumulates, and harder cleaning.
❌ "The wood goes white and slimy in 2 weeks, it's spoiled" — fluffy white biofilm is NORMAL on new wood (2–6 weeks). It disappears once the ecosystem stabilizes, or is eaten by plecos / cory.
❌ "I'll buy cheap wood from a general store" — these are often furniture offcuts or unknown wood. Pay a bit more for a verified source (a specialist aquascaping shop).
Where to buy
Specialist aquascaping retailers carry selected, fish-safe driftwood — search for the named types ("Malaysian driftwood", "Mopani", "Spider wood", "Manzanita", "Redmoor") from a reputable local or EU supplier rather than generic stores. Well-known EU names include Aquasabi (DE), Tropica (DK), Garnelio (DE) and Green Aqua (HU). Check availability and shipping for your country.

Did you know?
Driftwood doesn't just look natural — the tannins it leaches (humic and fulvic acids) gently lower pH and have a documented mild antibacterial and antifungal effect, which is part of why blackwater-style tanks are popular for sensitive fish like discus. The catch: activated carbon adsorbs those same tannins, stripping the color and the effect — so if you want the tannin benefits, leave activated carbon out of the filter.
Final checklist — driftwood and hardscape
- ☐ Wood type chosen: Malaysian (safe, accessible) or Spider wood (aesthetic)
- ☐ Wood boiled 30–60 min + soaked 1–14 days until it sinks on its own
- ☐ Wood free of resin, mold, rot smell — checked before buying
- ☐ Layout using the Golden Ratio (focal point at 1/3, not center)
- ☐ 40–50% open footprint for discus swimming
