Lights are out but I have seen some movement.
Sorry, but this bears repeating - turning the lights out for Amyloodinium infections does not help - this species does not have chloroplasts. Lowering light levels helps against overall stress, but keeping the tank fully dark disrupts the fish's ability to feed.
