I just got a rubber pleco and im wondering if there fins ever go up. My rubber pleco has his dorsal fin down but also his tail fin is condenced together making it look like he doesnt even have a tail. Since all of his fins are tucked in (except the pectoral fins) he just looks like a weirdish big blob that ends in a tiny tip (like a rain drop). So is my new pleco going to ever put his fins up?
