My last koi angel has been loosing and regaining his fins on and off for the past few months due to an internal parasite (I treated with several meds and every fish was cured except him) but now to top it all off I wake up yesterday morning and he only has one eye left. As of now he's acting friendly as always just has a hard time seeing people but wouldn't you if you only had one eye. Only thing is he isn't eating. I want him to get the best life he can for a diseased, half-blind fish so he doesn't wind up like his brother did. What would be some good methods to try to get him to start eating again? I realize I'll have to really target feed him probably but that's fine.
