They were around 2.5" female and 3.5" male when I got them first week of February this year, so best guess is that they are around a year old to maybe 13 months. Haven't pulled them to measure for a while, eyeballing is guess the male is around 9" and the female 7". They would probably be larger if they weren't trying to spam all the time. They've had 5 successful spawns so far. Lady spawn was 4 weeks ago and still in tank with them. The fry in pic are from 9 weeks ago, and are in the refugium portion of the dump for my 300g. For some reason they grow faster in there than in the 40g I was using as a grow out. I'm guessing it has something to do with the larger water volume.
