Hello, Barry is a 13yr old oscar we rescued at 8yrs old from a guy moving. He is blind with cataracts which happened in the last 6months. We thinks he sees shadows though. We are having trouble feeding him. He has only eaten Tetra large cichlid pellets his whole life and we could never wean him off. We had success splashing the water to get him to come up to eat. Tapping the tank at the top. But now he is freaked out since we went through a course of antibiotics for hith. I've tried shrimp from the grocery store with long tweezers, all foods you can think of with the tweezers. I know maybe time will help but going without food might stress him out and cause his hith to come back. Any thoughts?
