I guess you should have posted it in the disease forum, but what the hell...
I don't know if this is normal coloration: I know pleco's will change color, to blend into their environment (for example: black gravel results in very dark, sometimes even pitchblack pleco's). My own pleco's have different colorations as well, changing from time to time. But yours has an odd coloration.
Is he behaving and eating normal?
Sorry, I can't help you...
btw: isn't this the pleco that you have beaten up by Flipper?
