A few of the differences between ocellaris and perculas include the color of the color of the eyes, the number of the dorsal spines, and the thickness of the black lines of the body. Typically, perculas have more orange in the eyes, 10 dorsal spines (vs 11 on the ocellaris), and thicker black lines on the body. If you can get a clearer picture of the head and side then we can probably help with the ID.
I’d read that description but this guy doesn’t fit into the typical mould. She’s got black tipped fins. That’s what’s throwing me off. Otherwise looks like an ocellaris to me. I dunno. What do u think?
