Heavily doubt it. Polys are very varied in terms of colour, so it's probably a mix of catch locality genetics, substrate and lighting. The other polys in the back are also green it seemsPerhaps it's a recessive trait for color like how the red in red lizard catfish had to be bred out of them to show.
Green color is natural and common color for delhezi in wild.Very nice fish Giseok!
