I had a scare after seeing ich in my display tank on three other fish and treated the 275 gallons with enough copper safe for a 200 gallon tank. The ray now has what looks like raised black spots throughout the body and small patches of light brown tear drop shaped spots about the size of large ich under her eyes and along other parts of her body (predominately the eyes). I'm currently doing a large water change after rereading the specifics of which medicines are safe for rays. Does anyone have any advice? I should have been more cautious but I misread a thread saying there was a hype on medications hurting rays
