So back a couple of months ago I got a L14 pleco. For the most part he would hang out on the bottom and come out during feeding time. Recently he's being sucking on the glass and hanging out near the middle of the tank, keep in mind this guy usually stays ont he bottom. Also I see him munching on pellets, but his stomach doesn't seem as full as usual. if anything his stomach seems flat. physically he looks good. anybody?
