I bought this little guy as an orange spot (aka mustard spot) pleco from my lfs. But on planetcatfish they look a little bit different. Is this just natural variation, juvenile vs adult variation, or did I get something else? I think mine is a boy because he has a ton of those spiny things by his fins(arms)/behind his head. He’s about 3 to 3.5 inches. I adore him and he seems very happy in my angel tank but I just want to make sure he’s getting what he needs. I know pleco care can vary quite a bit between species.
