Well my 12 inch silver didn't eat this morning. When I got home from work no luck getting him to eat again. But I noticed he has got some eye issues. It looks like he might have rubbed them on something. He is breathing heavy with his mouth open and puffing out his gills buy they are not discounted or curled out . Any idea what it could be . He also has his weekly treat of small crickets last night could that have something to do with it?
