Choose leaves carefully
Some keepers use dried botanicals as cover and grazing surfaces. Leaves gathered outdoors may carry pesticides, road residue, or unknown contaminants, so source matters.
Choose aquarium products with clear identification and preparation guidance. Do not assume that a leaf is safe because it looks clean or comes from a familiar tree.
Add slowly and observe
A new botanical can release tannins and alter the appearance of water. Add a small amount first and track the tank's response rather than adding a handful at once.
Remove material if it breaks down excessively, traps debris, or contributes to a water-quality problem. It is an optional habitat feature, not a required shrimp food.
For your own tank
Start with one known, prepared leaf and observe how it softens and changes the water color. Remove it if it creates excessive debris or an unwanted parameter shift. Botanicals are optional; shrimp can thrive without collecting leaves from outdoors.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
