Xingu would be my guess
Some will say azul but I was reading azul don’t have the red tails
Which leads me more to xingu
Hopefully an expert will chim in
To me personally it looks like neither species mentioned, to me it looks like a cichla pleiozona but I could easily be wrong as I don't have much experience with pbass. But with the colors, pattern and facial structure I would say cichla pleiozona.
I think my fish hav 4 fathers...lol..Anyway my arowana is chasing him so i'm not sure how long i can keep him.. he's almost as big as my arowana so i'm keeping a close eye..If i've to chose i'll obviously choose my electric bb arowana
