My porcupine puffer seemed a little lethargic last week but was eating. A couple of days ago I noticed his eyes got all foggy. I was assuming it was flukes. I gave him a fresh water bath yesterday for 5 minutes. No noticeable change in appearance but he was definitely more active after that. Since the eyes were still foggy today, I did a fresh water bath for 10 minutes. He is active as ever now, but no noticeable difference in the eyes. Any ideas or suggestion? I have attached the latest pictures. Hard to take when he is moving so much, but I think it captures it fairly well. The second picture shows how part of his eye is clear.
