• Branch form at a bigger scale — the same forking, fine-textured branch wood as the Medium and XL pieces, in the 30–40 cm range that reads as a full aquascape centrepiece rather than a secondary accent.
• One dominant piece — sized to anchor a standard 60–90 cm aquarium as the single structural feature, rather than needing several smaller pieces stacked together.
• Grows biofilm — the branching surface develops the biofilm and microbial layer shrimp and shrimplets graze on across a larger surface area than the Medium piece offers.
• Natural tannin release — a larger piece leaches more tannin than Medium, giving a stronger blackwater tint that tapers off over several weeks.
• Every piece unique — hand-selected from natural stock, so shape, branching and colour vary piece to piece; the piece received won't match a photo exactly.

Bioscape sells this branch wood as single pieces in three sizes, and as multi-piece boxes for anyone furnishing several tanks or one large aquascape at once.

Large is the size to reach for on a standard 60–90 cm tank where one branch piece should carry the whole layout. Drop to Medium on a nano tank where a smaller piece won't overwhelm the scape, or step up to XL on a bigger show tank. The 10-piece box suits anyone building one large branching layout from multiple pieces, or furnishing more than one tank at once.

Suitable for standard freshwater aquariums, shrimp colonies and planted tanks wanting a single dominant branch structure and a blackwater tint. Not tested or sold for marine or reef use — treat it as a freshwater piece only.

New wood floats, and a piece this size takes longer to waterlog than a smaller one. Soak it in a bucket of water for two to three weeks, changing the water every few days to reduce the initial tannin release, or boil it in batches — a large piece may need to be boiled over more than one session to fit the pot. Expect a noticeable tannin tint in a new tank for the first few weeks; it's cosmetic, not a water quality issue, and fades as the wood settles in. Use a black-water conditioner or activated carbon if a clearer tank is wanted sooner.

As a natural product, Bioscape Shrimp Wood is sold as-is rather than under a manufacturing warranty, though your rights under Australian Consumer Law still apply if a piece arrives damaged or not as described. Ships by standard parcel post.

Will one piece be enough to scape a 60–90 cm tank?

Often yes. At 30–40 cm, a Large piece is sized to work as the sole structural feature in a standard tank, though many aquascapers still add a second smaller piece for balance.

Does it need to be soaked before going in the tank?

It's not compulsory, but new wood floats until it's waterlogged, and pre-soaking cuts down the initial tannin release. Allow longer than for a smaller piece — two to three weeks of soaking, or boiling in batches to speed things up.

Will the piece I receive look like the photo?

Not exactly. Each piece is hand-selected from natural stock, so shape, branching angle and colour vary — the photo shows the style and size range, not the individual piece.

Is it safe for shrimp?

Yes — this is the intended use. The branching surface develops biofilm that shrimp and shrimplets graze on, and the wood itself doesn't affect water chemistry beyond the tannin tint.
