Sailfin Molly Identification Help

[mcarm]

Hi - first time poster

I have had my 40g tank up for a couple of months and recently added two sailfin mollies. Beautiful fish - I am just wondering if anyone can help me identify if they are males, females or both? I 'think' they are both male...sound right?

Thanks. I am lovin' this hobby!!

They both have pointed tail fin so they appear to be male mollies.
