I have disagreed with Bruce before -

- but not this time. The body coloration and pattern is not BG but is somewhat RES. The body shape is BGish. Note the length of the pictorial fin's length (see below) - long like a RES. Seems to be a gray edge to the opercular flap which is not BG but is hybrid and RES.
Not positive of its heritage but it is not a pure BG and has some RES traits. Could be other genes in there as well.
