Ok, I thought Oscars had scales. Then I was told they didn't....THEN I was told they did. My question: Do Oscars have scales? The reason I'm asking is my Oscar has Ich. I got some Wardley's Ick Away, and on the back it says not to use on scaleless species. I've already added the first dose! So if he doesn't have scales, what's going to happen to my little guy?
