Please ID My silver dollars

Hi, I've been curious if my two silver dollars are the same species? They were both sold as metynnis argenteus. Is the one with
spots a different type or are spots common markings for a metynnis argenteus? Thanks

Two different SD's. More then likely a Meytinnis Lippincottianus (based on length versus height). That would be for the spotted in the picture. The other IMO would be right as an Argenteus.

Thanks!! As they've grow over the years it become clear they were different.
