I Would like some input. The picture I took shows him in his average color. He has really beautiful golden color to him. As you can see his tail fin has a blue tint which makes me think he's a grass pick. Sometimes his tail fin gets a lot more blue and his other fins turn slightly blue. Other times he gets darkish brown/red with a more pronounced black spike under his eyes, resembling more Redfin. Hes still quite young (close to 4 inches) so maybe ID at this time isn't possible. One would assume that having the blue tint in the fins should mean he's a grass but I'm not sure.
