What it does
Helps create botanical texture, hiding edges, grazing surfaces and visual habitat detail as it settles.
PRODUCT DETAILS
Open product details
The half-cup shape creates a ready-made hide area for shrimp, fry, small peaceful fish, bettas and suitable bottom dwellers. It can be used as a natural cave, a shelter zone or a hard botanical detail among leaf litter, pods, cones, bark and wood.
Once waterlogged and matured in the aquarium, the textured shell and fibres can become grazing surfaces 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 1 × Coconut Cup / Cocos nucifera botanical cave Approx. size: 12–20cm, with natural variation. You receive one single botanical piece. Packed dry, small batch and labelled by Blackwater Botanical Aquariums.
Key benefits
1) Natural cave / hide The cup shape creates a shelter area and line-of-sight break for shrimp, fry, shy fish, bettas and suitable bottom-dwelling livestock.
2) Strong botanical structure Coconut cups add a natural cave-style detail to leaf-litter scapes, blackwater aquariums and biotope-style layouts.
3) Biofilm grazing surface The natural shell texture and fibres give biofilm a place to develop over time. Shrimp, snails and other grazing livestock may explore mature botanical surfaces in the aquarium.
4) Micro-habitat detail The hollow interior, rim and natural shell texture create little exploration zones among leaves, cones, bark, seed pods and driftwood.
5) Gentle tannins and humic substances Like many natural botanicals, Coconut Cups may gradually release tannins and humic substances. The visible tint depends on the piece, tank size, KH, pH, filtration, water changes and how many botanicals are used.
6) Works with mixed botanicals Use Coconut Cup with leaf litter, cones, bark, smaller pods and driftwood to build a layered natural aquarium habitat with more depth and shelter.
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 cup where shrimp, fry, plecos or shy fish can explore, graze and shelter. Check the opening and position so livestock can enter and exit safely. Use with leaves, cones, bark and wood for a more natural botanical layout. 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 one.
Best for Shrimp tanks and shrimp colonies Bettas and small peaceful fish Pleco caves and bottom-dweller shelter where the size is suitable Fry and juvenile fish shelter Blackwater and botanical method aquariums Natural biotope-style layouts Leaf-litter scapes with wood, cones and pods Aquascapes needing a natural cave / hide botanical 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.
HOW TO USE / LAYOUT GUIDANCE
- Position safely so shrimp, fry, plecos and suitable bottom dwellers can explore and exit freely.
- Some pieces may float at first and sink later once waterlogged.
- Remove or replace if the piece becomes damaged, trapped with debris, or unsuitable for your livestock.

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
Amphibian 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.
AMPHIBIAN ENCLOSURE COVER
Suitable dry pieces can add natural cover and visual structure around established substrate and planting after scale, edges, moisture and species suitability have been checked.
AMPHIBIAN ENCLOSURE STRUCTURE
Use suitable natural forms as secondary structure only where moisture, scale, edges and the needs of the amphibian have been checked.
PREPARATION & SAFETY
Best for
Layouts where the customer wants visible natural structure, not a rushed water change.
What it does not do
It does not treat disease, replace filtration or guarantee pH, GH or KH outcomes.
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
What should I expect?
Expect natural texture and habitat detail. Exact colour, shape and breakdown speed vary by product and aquarium.
When should I slow down?
Pause or remove excess botanicals if livestock look stressed, water clouds unexpectedly or the tank is already unstable.
