Cholla Wood

The hollow tubular skeleton of the dried cholla cactus -- a uniquely structured hardscape piece that provides exceptional shrimplet shelter, dense interior biofilm, and a natural aesthetic unlike any other wood in the catalog.

Hollow Tubular Structure Exceptional Shrimplet Shelter Dense Interior Biofilm Slow Tannin Release Fully Decomposes Over Time Natural Cactus Skeleton

Cholla Wood is the dried skeleton of the cholla cactus (Cylindropuntia sp.) -- a hollow, cylindrical tube of interlocked woody fibres with naturally occurring openings along the entire length that create a structure unlike any other hardscape or botanical item in the catalog. The hollow interior, accessible through the openings along the sides, provides a physical shelter environment that shrimplets actively seek out and that adult shrimp explore for the dense interior biofilm that accumulates within the fibrous walls of the cylinder. It releases tannins slowly as it softens and begins to decompose over weeks, contributes to a mild blackwater aesthetic, and provides a continuous foraging surface that improves in biofilm richness as the wood softens with time. Cholla Wood is simultaneously a hardscape element, a botanical item, and a food source -- it decomposes fully over several months and can be replaced with fresh pieces as old ones break down. Safe for all Neocaridina, Caridina, and snails.

Structure, Biofilm and Use

Hollow tubular structure with openings along the full length -- unique in the catalog -- the defining structural quality of Cholla Wood is the hollow interior cylinder accessible through naturally occurring gaps in the fibrous woody wall. This creates a three-dimensional foraging and shelter environment inside the wood piece itself -- shrimp enter through the side openings, move through the interior, and forage on the biofilm that develops on the inner wall surfaces. No other hardscape or botanical item in the catalog provides this enclosed, navigable interior structure. Shrimplets actively shelter and forage inside the hollow interior -- the openings in the Cholla Wood cylinder are sized appropriately for shrimplets to enter and navigate the interior freely while being too small for most fish or larger animals to follow. In tanks with an active breeding colony, Cholla Wood pieces reliably accumulate shrimplets in their interior within the first few weeks of introduction -- making each piece a visible, productive shrimplet concentration point that is easily observed from the front glass. Dense biofilm develops on interior and exterior surfaces over weeks -- both the exterior fibrous surface and the interior wall of the cylinder develop biofilm progressively as the wood softens with time in the water. The interior biofilm is typically richer and more diverse than the exterior because the enclosed environment is more sheltered from flow and light -- conditions that favour the microbial communities that produce the biofilm shrimp actively seek. Slow tannin release contributes to mild amber water tint -- as Cholla Wood softens and begins to decompose, it releases tannins that produce a gentle amber tint in the water and contribute mild humic acids to the water chemistry. The release is gradual and moderate rather than the large initial release of some botanicals -- a pre-soak is optional and reduces the initial tannin release without significantly affecting long-term biofilm development. Decomposes fully over several months -- replace as pieces break down -- Cholla Wood is not permanent hardscape -- it softens progressively, the fibrous structure eventually fragments, and the piece fully decomposes over two to four months depending on tank temperature, flow, and biological activity. When a piece begins to fragment significantly, replace it with a fresh one to maintain the shelter and foraging structure it provides. Floats initially -- soak or weight before use -- dry Cholla Wood floats. Soak in water for 24-48 hours before introduction to waterlog the fibrous structure and eliminate the floating period. Weight with a small stone placed inside the hollow interior if the piece continues to surface after soaking.

Getting Started

1Soak for 24-48 hours before introduction -- submerge in a separate container of water to waterlog the fibrous structure. The wood sinks reliably after 24-48 hours of soaking. Discard the soak water if you want to reduce the initial tannin release in the tank.
2Position horizontally on the substrate in an open, visible location -- horizontal placement keeps the side openings accessible for shrimp entry and exit. Position in a visible area of the tank where shrimplet activity inside the hollow can be observed from the front glass.
3Allow biofilm to develop -- do not disturb for the first two weeks -- after introduction, leave the Cholla Wood undisturbed for two to three weeks to allow biofilm to establish on both exterior and interior surfaces. The richest foraging period begins around week two to three as the interior biofilm reaches peak density.
4Replace when the piece begins significant structural fragmentation -- Cholla Wood is a consumable item rather than permanent hardscape. Introduce a fresh piece alongside a decomposing one so that the tank always has at least one piece at the peak biofilm stage.
Bonus Tip

A piece of Cholla Wood positioned horizontally at the front of the tank on dark substrate -- close enough to the front glass that the interior is visible from outside -- creates the most engaging shrimplet observation point in the catalog. Within two to three weeks of introduction to an established breeding colony, the interior of the piece will reliably contain three to ten shrimplets at any given time, clearly visible through the openings from outside the tank. In a planted tank where shrimplets are otherwise difficult to spot, Cholla Wood makes juvenile observation effortless and continuous.

Policies & Disclaimers

Natural materials, preparation, water effects and the existing terms that apply to your order.

Natural variation & representative photos

Leaves, cones, pods, bark and cholla are natural materials. Pieces can vary in shape, color, thickness, texture and markings. Photographs show examples; they are not a promise of an identical piece or a matched set.

Use the listing and selected option for the quantity and any size range. A pack sold by count is not a standardized weight, and the same number of large pieces can add more material to an aquarium than smaller pieces. Wood, pods and bark also differ from one another in density and structure.

Dry leaves and other delicate materials can be brittle. Small edges, loose fragments or surface irregularities can occur, but this is not a blanket exclusion for damage. If an item appears substantially damaged, incorrect or short, document it and contact us.

Preparation: follow the particular listing

Review the preparation instructions for the exact botanical before adding it. Leaves, bark, cones, pods and wood do not all need the same treatment. Check for loose debris and rinse as appropriate; do not use soap, detergents or scented cleaning products.

Where the product calls for soaking or boiling, follow that guidance and allow material to cool fully before aquarium use. There is no universal boiling time or preparation recipe here. Do not assume preparation makes a natural item sterile or suitable for every species.

Prepare only what you intend to use and assess the material before introduction. If you are uncertain about a smell, coating or unexpected condition in the received package, ask before putting it in an established tank.

Floating, sinking & placement

Dry botanicals can float while they absorb water. Sinking time depends on the material, thickness and preparation; do not assume all pieces will sink immediately or on the same schedule.

Position pieces so they cannot block equipment, obstruct water movement or create an unsuitable tight space for your animals. A decorative shelter still needs to suit the size and behavior of the inhabitants. Check placement again as the material softens or moves.

Tannins, amber water & pH

Many botanicals release tannins and other dissolved organic compounds, which can tint water amber or brown. The amount and speed of release vary by material, preparation, quantity and aquarium maintenance. Color intensity is not a dosing measurement.

Do not use water color as a substitute for testing pH or carbonate hardness (KH). Your water’s buffering capacity affects how it responds. A botanical does not provide a predictable fixed pH reduction or replace appropriate water preparation.

Introduce changes cautiously, especially in low-KH systems. Choose botanicals to suit the inhabitants and monitor actual water conditions rather than adding more to chase a darker color or an advertised visual effect.

Biofilm, softening & decomposition

Once submerged, natural materials become surfaces for microorganisms and gradually break down. A film can develop on wet wood or other botanicals, and shrimp may graze these surfaces. Leaves can soften, develop holes and eventually fragment as part of that process.

The pace differs between leaves, cones, bark, pods and wood. A rapidly softening leaf and a slowly changing piece of cholla should not be expected to last equally long. There is no universal replacement interval for all botanicals.

A film that develops after aquarium introduction should not be confused with visible mold or suspicious contamination inside a dry package. If newly received material appears compromised, photograph it and contact us before use. Do not dismiss every unusual coating or odor as harmless biofilm.

Add gradually & observe the aquarium

Adding a large amount of organic material at once can increase microbial activity and oxygen demand. Start conservatively, maintain water circulation and monitor the aquarium’s response before adding more.

Check water quality and observe your animals. Unexpected cloudiness, odor or distressed behavior calls for investigation, not simply another addition of botanicals. Remove excess decomposing material when appropriate to your tank and maintenance routine.

Botanicals can provide structure and grazing surfaces, but they do not replace filtration, water changes or a suitable diet. They are not a guaranteed treatment for illness or a promise of improved breeding, survival or coloration.

Storage before use

Keep unused dry botanicals dry and protected from moisture and contamination. Avoid storing them where aquarium splashes or condensation can reach the package. Retain the product label and keep different materials identifiable.

Do not put soaked pieces back into the dry supply. Follow any product-specific storage guidance, and ask about newly received material that has unexpected dampness or visible contamination.

Package problems, incorrect items & questions

Inspect your botanicals and its packaging on arrival. If the package is torn, wet, leaking, incorrectly labeled or appears to contain the wrong item or quantity, contact support@superiorshrimpaquatics.com promptly with your order number and clear photos. Include the label, the affected product and packaging so we can understand the concern.

Keep the original packaging and avoid using a product that appears contaminated or compromised while you ask for advice. This is practical documentation guidance, not a new claim deadline or a promise of a particular resolution. A routine unopened return and a report that an item arrived damaged or incorrect are different concerns; tell us which applies.

Existing return terms & exchanges
