So I have a rubber lip pleco and since ive gotten him (about two weeks ago) I never see him unless hes in a piece of decor you can see into. He spends most of his time on a peice of driftwood in a small hidden cave hes made under it. Whenever I feed him I never see him out either the only reason I know hes eating is because theres always a large chunk out of the wafer. I know they are nocturnal but hes just such a cool fish and I wish I could see him more. I also noticed since I got him hes gone from solid grey to having yellow stripes on him and was wondering what that was. Any info is useful. Thank you.
