What it helps visualise
The extra scene images are look samples: they help customers picture the product in a living aquarium-style habitat, not as a promise that every tank will look the same.
The hollow bark-tube shape gives shrimp, fry, suitable small fish and small plecos a natural place to explore, hide and graze while adding a realistic botanical look to leaf-litter, blackwater and biotope-style layouts.
Use them among leaf litter, cones, pods, bark and driftwood to build a more layered aquarium habitat. Once waterlogged and matured in the aquarium, the bark surfaces can become grazing zones where biofilm develops over time.
These are natural habitat and enrichment pieces, not medicines. Use them as part of a balanced botanical layout with stable water, mature filtration and normal aquarium care.
What you receive Choose from 1pc, 3pcs or 5pcs Catappa Bark Tubes / Indian Almond Bark natural botanical tubes. Approx. size: 7–9cm, with natural variation. You receive the pack size selected from the variation menu. Packed dry, small batch and labelled by Blackwater Botanical Aquariums.
Key benefits
3) Biofilm grazing surface The rough bark texture gives biofilm a place to develop over time. Shrimp, snails and other grazing livestock may explore mature botanical surfaces in the aquarium.
4) Micro-habitat structure The openings, bark texture and tube form create small shelter pockets among leaves, cones, pods and driftwood.
5) Tannins and humic substances Like many natural botanicals, Catappa Bark Tubes may gradually release tannins and humic substances. The visible tint depends on the bark, tank size, KH, pH, filtration, water changes and how many botanicals are used.
6) Works with mixed botanicals Use Catappa Bark Tubes with leaf litter, cones, seed pods and driftwood to build a layered natural aquarium habitat with more depth, shelter and grazing surfaces.
How to use Rinse before use. Do not use soap or chemicals. Optional: pre-soak for 1–7 days to help sinking and reduce the initial tannin release. Add gradually, especially in soft water, low-KH systems or smaller aquariums. Place the tubes where shrimp, fry, plecos or shy fish can explore, graze and shelter. Check the position so livestock can move through and around the tubes safely. White biofilm at first is normal and is often eaten by shrimp and snails. If any piece becomes unsightly, simply remove it and replace with a fresh piece.
Best for Shrimp tanks and shrimp colonies Plecos and small bottom dwellers where the size and placement are suitable Bettas and small peaceful fish Fry and juvenile fish shelter Blackwater and botanical method aquariums Natural biotope-style layouts Leaf-litter scapes with wood, cones and pods Aquascapes needing natural bark tube shelter Aquarists who want to build their own custom botanical mix
Important notes Natural products vary in colour, shape, size, opening, thickness and texture. Approximate size range is provided as a guide only. Some pieces may float at first and sink later. Pre-soaking can help. Botanicals may release tannins and soften the visual tone of the water. Effects vary depending on tank size, KH, pH, filtration and how much is used. Carbon, Purigen and some filtration media may reduce visible tannins and water colour. Botanicals are natural habitat and enrichment tools, not medicines. Not for human consumption.

OTHER CUSTOMER ROUTES
OTHER NATURALISTIC HABITAT USES
Beyond aquarium use, selected dry leaves, pods and woody pieces can also add natural structure, cover and surface complexity to suitable paludarium, vivarium and bioactive setups. Choose materials to suit the scale, moisture level and animals in the enclosure.
Paludarium
Bioactive terrarium
Reptile enclosure
PALUDARIUM MARGIN
Use suitable leaves, pods and woody pieces through damp margins and transitional areas to connect the aquatic and terrestrial parts of a naturalistic layout.
BIOACTIVE FLOOR
Leaves and suitable harder pieces can form part of the litter and structural layer used around an established bioactive substrate. They are not a complete substrate by themselves.
REPTILE ENCLOSURE COVER
Suitable dry pieces can add natural cover and visual structure around established substrate and planting after scale, edges and species suitability have been checked.
REPTILE ENCLOSURE STRUCTURE
Use suitable natural forms as secondary structure only where scale, edges and the needs of the reptile have been checked.
PREPARATION & SAFETY
What it does not do
It does not replace stable husbandry, cure disease or guarantee pH, GH or KH movement. Use it as a prepared botanical, not as a water-parameter shortcut.
PREPARATION
- Rinse all botanicals thoroughly before use. Do not use soap, detergents or household chemicals.
- If needed, pre-soak harder pieces for 1–7 days to help them sink and to reduce the strongest initial tint.
- A white or translucent biofilm may appear as botanicals begin to soften. This is a normal part of botanical decomposition and is commonly grazed by shrimp and snails.
SAFETY
- Add botanicals gradually, particularly in small aquariums or very soft, low-KH water.
- Natural pieces vary in size, shape, colour and texture.
- Botanicals are not a treatment and do not guarantee a specific pH, GH or KH change.
- Remove or reduce botanical material if livestock show signs of stress.
- For aquatic and naturalistic hobby enclosures only. Not for human consumption. Keep unused material away from children and non-target pets.
- Individual botanical pieces are not a complete substrate or complete diet for enclosure animals.
- Approximate size range is a guide only.
- Some pieces may float at first and sink later.
FAQ
Open FAQ
Will every piece look identical?
No. Natural botanicals vary in colour, curve, texture, openings and how they change once soaked.
Can I add several pieces together?
Only if the tank has enough space and livestock are behaving normally. A measured first placement is safer.
What if the piece floats at first?
Some natural botanicals float before they waterlog. Pre-soaking can help, and positioning should remain safe.
