I got this as a "Japanese Perch". But some people are saying it's a barramundi. And now i'm really unsure... So it would be awesome with some identification help!
When the previous owner had it, it was colored 2 times with those white markings, and the white line along with the forehead that the Japanese perches get. (does barras have that too?)
