If copper was maintained at 2.25 ppm for 30 days straight, he should be clear of ich. Please provide a clearer photo and/or video.

Based on the treatment given, it is unlikely to be ich.

These filefish are tough to diagnose because their skin is naturally spotted and bumpy.

We need a clearer view. Cleaning the glass and taking a closer video would help.

Second everyone above. A clear picture under white lights will help with ID of the infection
