30-40 cm long
Bioscape Spider Wood Medium 30 - 40cm
Ten pieces of fine, twisting wood for nano to mid-size scapes. Bioscape Spider Wood Medium ships as 10 pieces of slender, branching root wood, sized to build fine tree and root-tangle structures without overwhelming a smaller tank.
Key features
- 10-piece pack – ships as ten pieces of the Medium, 30-40 cm size grade, confirmed by the pack listing.
- 30-40 cm grade – sits between Small (20-30 cm) and Large (40-50 cm) in Bioscape's Spider Wood range, suited to nano through to mid-size layouts.
- Slender, twisting branches – fine root-and-branch shapes good for tree-style scapes, moss attachment and shrimp-tank hardscaping.
- Lower tannin release – noticeably less tannin than Mopani or Malaysian driftwood.
- Every piece unique – natural product; shape and colour vary piece to piece, and the photo is a representative sample.

Which size do I need?
Bioscape grades Spider Wood by branch length: Small (20-30 cm) suits nano and shrimp tanks, Medium (30-40 cm, this listing) suits nano to mid-size layouts wanting several pieces to build a scape, Large (40-50 cm) suits standard to larger tanks, and XLarge (50-60 cm) is scaled for centrepiece layouts. Because Medium ships as a 10-piece pack, it's the size grade best suited to building a full root-tangle or forest-style layout rather than a single accent branch.
Suitable for, and not suitable for
Suitable for freshwater aquascaping, particularly nano and shrimp tanks, and also used in reptile enclosures and terrarium or paludarium builds. Bioscape doesn't publish a marine-safe claim for Spider Wood, so treat it as a freshwater and terrarium product.
Care and maintenance
New Spider Wood is dried for shipping and floats – weighting pieces down for about a week is usually enough for them to waterlog and sit on their own, though timing varies and denser pieces can take longer. Presoaking or boiling speeds up sinking and helps reduce tannin release. A harmless white biofilm sometimes forms on new wood underwater; shrimp, snails and some fish will graze it off.
Warranty and delivery
Covered against manufacturing and packing defects under Bioscape's warranty, in addition to your rights under Australian Consumer Law.
Common questions
How many pieces do I get?
Ten pieces of the Medium, 30-40 cm size grade.
Will it turn my water brown?
Some tannin release is normal with any natural wood, but Bioscape's Spider Wood releases noticeably less than Mopani or Malaysian driftwood. Presoaking or boiling reduces it further.
Is this a good size for a shrimp tank?
Yes – the Medium grade's finer branching and multi-piece pack make it well suited to nano and shrimp-tank hardscaping.
Does it float?
Yes, initially. New wood is dried for shipping and needs weighting down until it waterlogs, which typically takes around a week but can vary.
