SuperFish Spiderwood Branches:

A Guide to Nature’s Architecture

In the aquascaping community, Spiderwood (often derived from the roots of Rhododendron or Azalea species) is considered the gold standard for creating intricate, “nature-style” layouts. SuperFish Spiderwood is a premium selection of these roots, prized for its spindly, branching structure that mimics the tangled undergrowth of a tropical riverbank or a fallen forest canopy.

Whether you are building a high-tech “Iwagumi-hybrid” or a simple “low-tech” community tank, Spiderwood offers a unique aesthetic that bulkier woods, like Bogwood or Mopani, simply cannot replicate.

Around 15-25cm in length.

1. Physical Characteristics

SuperFish Spiderwood is distinct for its “spider-like” appearance—featuring a central trunk that radiates into numerous fine, twisting branches.

• Colour: When dry, the wood is a pale, sandy tan. Once submerged, it deepens into a rich, warm reddish-brown.

• Texture: The wood is relatively soft compared to hardwoods. It has a smooth bark-like surface that is excellent for the attachment of epiphytic plants.

• Buoyancy: Spiderwood is notoriously buoyant. Unlike heavy African hardwoods, it will almost certainly float when first introduced to the aquarium.

2. Pre-Treatment and Preparation

To ensure the best results and avoid “aquarium-water-woes,” proper preparation is essential.

The “Soaking” Period

Because Spiderwood is light and dry, it can take anywhere from 1 to 3 weeks to become fully waterlogged.

• Option A (Patience): Weigh the wood down in a bucket of dechlorinated water using a heavy stone until it stays down on its own.

• Option B (Anchor): Secure the wood to a piece of slate or a heavy rock using aquarium-safe screws or cyanoacrylate gel (super glue) and bury the anchor in the substrate.

Tannin Release

Like all natural woods, Spiderwood releases tannins into the water.

• The Effect: This will tint your water a light “tea” colour. This is actually beneficial for many fish (like Tetras and Bettas) as it has mild antibacterial properties and mimics their natural environment.

• The Cure: If you prefer “crystal clear” water, boil the wood for 1–2 hours before use or use a chemical filtration media like Seachem Purigen in your filter to strip the tint.

3. The “White Slime” Phenomenon

A common concern for hobbyists new to Spiderwood is the appearance of a thick, translucent white “fuzz” or fungus a few days after submersion.

• What is it? This is a harmless bio-film caused by naturally occurring sugars and nutrients leaching from the wood, which are then consumed by bacteria.

• The Solution: You do not need to remove the wood. It will eventually disappear on its own. Alternatively, Amano Shrimp, Bristlenose Plecs, or Snails view this slime as a gourmet delicacy and will clear it in days.

4. Aquascaping Techniques

Spiderwood is the “skeleton” of a planted aquarium. Its fine branches provide the perfect scaffolding for aquatic flora.

• Epiphyte Attachment: The many nooks and crannies are ideal for wedging or gluing Anubias Nana Petite, Java Fern, or Bucephalandra.

• Moss Trees: By tying Christmas Moss or Java Moss to the tips of the branches, you can create the illusion of miniature underwater trees.

• Depth and Perspective: Position the wood so the branches point towards the front of the glass. This creates “lines of sight” that draw the eye deeper into the tank, making a small aquarium feel much larger.

5. Benefits for Livestock

Spiderwood isn’t just a decorative item; it serves several biological functions:

1. Hiding Spots: The dense branch network provides a “safe zone” for fry and shy species like Cichlids or Shrimp.

2. Grazing Surface: As the wood slowly breaks down, it creates a surface for biofilm and algae to grow, providing a constant natural food source for grazing fish.

3. Water Chemistry: It provides a very slight acidification of the water, which is preferred by most South American and Southeast Asian species.

6. The Verdict

The Pros:

• Unrivalled Intricacy: No other wood offers such fine, delicate branching.

• Fish Safe: 100% natural and non-toxic.

• Lightweight: Easy to position and move during the “hardscaping” phase.

The Cons:

• Buoyancy: Can be frustratingly difficult to keep down initially.

• Slime Growth: The initial bio-film can be unsightly for a week or two.

• Softness: Will eventually decompose faster (5+ years) than denser woods like Mopani.
