Nice aros u got bro and nice pics to see which one is male/female....
Pic 1 (RTG) = Male
Pic 2 (HBRTG) = Female
Pic 3 (SR) = Male
Your aros are old enough to be brooders and having babys.
What u need to do is just waiting till 1 year and pray..hoping that there will be a aro pair...also pray that your aros are getting hony very quickly
