Fish ID

Anyone know these 2 types of fish? They are either mollies or platys, I just can’t tell which or what type. I forget what they were called and the pet store just called them “tropical fish”

The first one is the guy who has a red tail, and is front and center. Also, water is green due to medication

The bottom picture is definitely a silver lyretail molly. If the one in the top picture is the same size it's also a molly. Mollies get bigger than platys (especially lyretails)
