Long Spider Wood 90cm

• Sold as one piece – a 90 cm branch, long enough to be the sole hardscape feature in most large setups.
• Natural spider wood – fine, twisting limbs rather than a single solid trunk, in the azalea-root style used across freshwater aquascaping.
• Each piece is unique – shape, thickness and exact branching vary piece to piece; the photo is representative, not the exact piece you'll receive.
• Spans tall tanks and open tops – long enough to break the waterline in paludarium and vivarium builds, not just lie flat in an aquascape.

Bioscape doesn't publish a weight figure for the individual branch – it's a natural product sold by the piece, and weight varies with how much branch structure survived selection. We're not printing a figure we can't confirm.

In a 180 cm tank, stand this piece upright at the back third for a full-height centrepiece that still leaves room either side for planting. In an open-top bioactive paludarium, angle it from the substrate up through the waterline as a combined climbing and basking branch.

Suitable for large freshwater aquascapes, open-top paludariums and terrariums where a tall branching centrepiece is wanted, and a common choice for bioactive terrarium and vivarium builds as a climbing feature. Not intended for reef or marine aquariums – driftwood is an organic material that will slowly break down in water, which has no place in a saltwater system.

Spider wood is buoyant and will float until it's waterlogged, so plan to soak or weigh it down before adding it to a display tank. Being the larger piece, this one takes noticeably longer to waterlog than the 60 cm branch – soaking in a bucket of water, changed every few days, can take several weeks for a piece this size. Tying or wedging it against rock, or using an aquarium-safe suction mount, holds it in place while it soaks down. Once submerged, spider wood releases tannins that tint the water a tea-brown colour – harmless, and the look many blackwater aquascapes are built around, but easily reduced with activated carbon or regular water changes if you'd rather keep the water clear.

Covered against being not as described under Australian Consumer Law. As a natural product, the branch you receive will vary from the listing photo in exact shape, thickness and colour – that's expected, not a fault. Being a long, awkward-shaped piece, it may ship in a larger box than the product size suggests.

Will it float?

Yes, at first, and more stubbornly than the 60 cm piece simply because there's more wood to waterlog. Budget extra soaking time before it will stay down on its own.

Will it turn my water brown?

It will release tannins that gradually tint the water tea-brown. This is cosmetic, not harmful, and can be reduced with activated carbon or more frequent water changes.

Is 90 cm too big for a standard tank?

For a tank under about 120 cm, a full 90 cm branch can dominate the layout – the 60 cm piece is usually the better proportioned choice there. This size comes into its own in larger tanks and open-top paludariums.

Can I cut it down if it's too long?

Yes – spider wood can be trimmed with a saw once it's dry. Many aquascapers buy a larger piece and shape it, rather than trying to size up from something too small.
