Hi,
My lionfish has gone blind. He at first became stressed out swimming into the live rock and sides of the tank. After a week he has felt his way around the tank to know where the rocks are and how long the tank is. He hasnt eaten for 3 weeks now. I try force feeding him white bait and green prawn meat but he coughs the food back out. He is shedding his cuticle once a week. My tank is 300 litres. Tank has been established for 2 years. Have had the lionfish for 18 months - 25 cm long. Nitrate is 80, Nitrite is 0, & Ammonium is 0. Phosphate is 4 after the last test. This is usually 0 and this is the first time its been above 0. PH is 8. Since the last test have done 30% water change. Previously we do a 25% water change every 3 weeks. There is no cloudiness in his eyes. No opaque covering over the lens or sign of a catarat. I also have a longhorn cow fish. Would the cow fish be secretting any poison? Our domino damsel, and blue ribbon eel appear healthy and fine. Also have a sea urchen in the tank. His feeding history - was feed fresh water fish for the first 3 months but havent feed him this since. Any thoughts on getting him to eat & the cause of his blindness? And can this be cured?
Many thanks,
