i think its an RTG as its gill plate shines like gold, but im not sure. that's why i wanted to have comments from people who are more experienced than me =)
It's not a RTG. It's a banjar.... The markings on the finages doesnt seen to belong to a golden and it's shine on the body doesnt match as well. The closest it can get is the banjar.
As for the goldish colouration, some banjar do feature a slight colouration on their gillplate. Attached is my banjar of 9 inches. You see the resemblem of the finage's black markings and colouration? Mine is taken under cool white lights.
