Keep the clip undisturbed
Rest the phone against a stable surface and record the aquarium during normal activity. Avoid tapping the glass or chasing shrimp into view.
Capture enough tank context to show the filter and affected area, while keeping the camera outside the water.
Add a useful description
Include when the behavior started, how many shrimp are affected, and any recent maintenance or additions.
List relevant water readings with test method and units. A video cannot reveal ammonia, hardness, or other chemistry.
Ask for observation, not a diagnosis
Explain what you are unsure about and request help identifying what to check next. Do not treat comments as a substitute for qualified veterinary advice.
Save the original clip and avoid filters or edits that could change color or movement.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
