I’ve had him for a few months now, I believe he’s a common sail-fin, he’s my first pleco (I’ve gotten a bristle nose since because he made me love plecos) but I have a few questions as well, do they change color? Because I changed the bottom from rock to sand and now he seems to be lighter in color. Also, are those little white dots on his face normal? He’s always had them.

I’m not sure how to add a video or picture so I’ll add a picture in the comments
