Dave if they were sexable 10 months ago then i would say you should not worry about it then. I get Aggies sexable at about 4 months or less so they are just over a year old I would say. In my florida heat house of a fishroom My Apistos live about 2.5 years so I would guess you safe as far as age goes. You are wise to buy young fish!
