Prepare a calm maintenance window
Use clean aquarium tools and switch off equipment only if needed for safe access. Trim a manageable portion rather than removing every plant at once.
Shrimp may hide during disturbance. Keep hands and tools away from animals and avoid crushing moss or uprooting hardscape suddenly.
Remove and inspect the debris
Collect loose leaves and stems so they do not clog the filter or decay unnoticed. Check that intake guards remain in place when equipment restarts.
If the trim stirs substrate or releases a lot of debris, pause feeding and observe the tank. Do not follow routine trimming with a drastic water correction unless tests indicate a problem.
For your own tank
Collect plant fragments before they reach the filter or settle into dense moss. Work in short sessions and leave shrimp cover intact. If a major trim is needed, avoid pairing it with a substrate clean or a large chemistry adjustment on the same day.
