Rubberlip pleco changed colors?

[clmags19]

I just noticed today my rubberlip pleco is a dark grey almost black color. Hes always been a light grey since i got him. Hes still a baby only 2 inches, do they get darker with age? Or is he stressed or something? All other fish are behaving normally....

My bristlenose pleco changes color all the time, it's normal.
