Thank you for your reply. I agree with you. The first fish it consumed was near death from a power head mishap. This incident was an unfortunate surprise for me. I'm remembering that right before the incident with the Naso, he was lingering dangerously close to and above the nem. I've made a couple of serious mistakes setting up this tank and this is one of them. I intend to keep the nem but perhaps not in this tank.
