I don't know much about them but I believe that is a picture of
Coreoperca kawamebari?
here's a pic of my
C. whiteheadi...got him from Rapps last batch

Not the greatest shot, they're fairly cryptic fish (or at least mine is) seems to prefer lurking back in the shadows
Slightly different pattern than the fish you showed a pic of, less red in the fins etc...I like those
C. kawemebari...hopefully someone will bring them in someday
Mine eats cut shrimp but only if he sees it hit the water...if it's just floating or sinking he doesn't see it as food..yet. Hoping he will figure out the feeding thing a little better soon, he has only been off live for a few weeks.
Mild territorial aggression towards other fish that come too close to his current hiding spot but he will back down in a hurry if they push back at him.
Hasn't grown much in length but has filled out considerably, not sure on max size.
I keep mine with some cool water fish, he seems fine in 68 to 70 degree water but per Fishbase they are a 'tropical' fish so I assume they can tolerate warmer temps just fine. I haven't tried it above 72 myself.
Thinking of getting more myself, I only have the one. Good luck if you try them, pretty cool fish.
