New aquarium plants with shrimp: origin, rinsing and separation

Before buying, ask about origin, product form and pesticide treatment. Rinsing removes loose material; keeping plants separately allows inspection. Neither demonstrates that an unknown chemical has disappeared. Where treatment is unclear, prefer better-documented stock.

Distinguish product forms

Tropica describes its own 1-2-Grow tissue culture as free from pesticides, snails and algae. This guarantee does not automatically cover a potted plant, another producer’s bundle or an opened cup stored elsewhere. Its product information specifically warns that some externally produced bundles are not guaranteed pesticide-free.

Prepare without false certainty

1. Keep the product name and ask for the supplier’s preparation instructions. A reassuring general sales description cannot replace that information.
2. Remove packaging, loose rock wool or culture gel as directed. Rinse carefully without unnecessarily damaging roots or rhizomes.
3. Inspect leaves, roots and attached material. Keep uncertain stock separately with its own tools, sufficient light and appropriate care.
4. Follow new growth and visible hitchhikers. Request product-specific information if treatment remains unknown; do not use shrimp as a safety test.

A fixed number of quarantine days cannot certify removal of unknown residues or every hitchhiker life stage. Avoid improvised bleach, salt or disinfectant baths. A method for one plant or organism is not a general shrimp-safety guarantee.

Dispose of clippings and unwanted organisms without releasing them into outdoor waters. If problems started after planting, use the post-introduction deterioration route.
