Great read guys, thanks. I have a FH, about 10" and a real fatty. He's a few years old, not sure exactly. Currently living in a 90 gal tank with no background and no gravel no decor.
Was wondering if I spice things up with the tank if he will show changes in color even if he's an adult? He's mostly dark green with dark red at his "chin/cheek" area. (sorry dont have pic). I like the way he looks already, just curious if an adult will still show much color changes. See him
