Males won't start showing their coloring until they are a year or two old. I have a male that is reportedly over three years old who is just now really showing his blacks. I don't know how reliable femoral pores are for sexing Malis. I know they aren't reliable at all for sexing Geryis. Hemipenile bulges are the best way to sex, but I don't know when those begin developing, either. I've not owned a Mali young enough to see the changes.
