Inspect the source and plant
Plants may arrive with snails, eggs, algae, or treatment residues. Ask the seller whether pesticides or fertilizers were used and whether the plants were grown submerged or emersed.
A separate holding container lets you observe hitchhikers and rinse debris without exposing the established colony. Keep the plant in suitable water and light while it is held.
Choose a method you can trust
Use only a plant-preparation method known to be compatible with shrimp and follow its exact instructions. Some chemical dips can damage plants or leave unsafe residues if misused.
When the treatment history is unclear, a longer separate observation period is safer than relying on a quick rinse. Do not place treated plant water into the shrimp tank.
For your own tank
A separate container is most useful when it has clean water, light appropriate to the plant, and enough time for observation. Remove visible snails and damaged leaves with clean tools. Never use a dip recipe unless the plant and shrimp safety instructions are clear.
