This fish was found mixed in with a tank of Satanoperca daemon's.
Can you guys confirm the ID of this fish?

GREAT pics (normally ID pics always suck and leave you holding your laptop in front of your face, thanks!).. Where exactly did you get the shipment from? There are no spots/lines under the dorsal fin, a large black spot on the top of the caudal peduncle, and the facial markings appear to break into a spotted muzzle, along with the large lips. This screams Satanoperca Mapiritensis to me but I am sure many will quickly pass it off as Satanoperca Leucosticta. My first guess says this fish is right about 4" TL correct?? My group is right about this size and the muzzle spotting is just now starting to break up. Let me know if you want a pic to compare.. :) BTW mine have the exact shade of red in the dorsal as well. Very unique and pretty. Let me know if you would like to sell it. ;)
 
Japes, Darth_Pike or Ed may disagree and jump in but I am pretty sure. See the below it is the best pic I can find of mine that includes the dorsal pattern. The right is a juvie, the left is an adult of unknown origins. My Juvies came from Jeff Rapps and are F1 european bred stock. I believe they were bred in Poland but that is just my opinion... It's an old pic, you should see them today ;)

I'm not touching this one with an answer based on these photos. There is so much variation in facial patterning between Satanoperca sp. locale variants. I do agree that the patterning is somewhat off for typical S. leucosticta, as they're tightly bunched (indicative of S. mapiritensis).

Could be a variant of S. leucosticta, S. jurupari, or S. mapiritensis. Based purely on being housed with S. daemon, if it came in with the same shipment it would indicate they're wild (Orinoco perhaps - granted that is hoping they wouldn't get mixed up as aquarium bred), in which case S. mapiritensis is a real possibility. JK47 makes a good observation about the lack of iridescent scales along the top of the back under dorsal hard-rays which S. leucosticta typically have to some degree.

I'd contact the LFS and try and get an answer from the supplier.
 
JK47: The fish is approx 3".

Hey guys, thanks for the help. Here are more pics, hopefully they're more helpful.
