We have two mature male fossies in a 210G tank and are growing out two more hoping for 1 girl.
Not sure how big your tank is but we have the 2 males in a 6' tank and at times I need a referee in there to split them up, 10 mature fossies are going to be a circus act methinks. They have broken equipment in the past on me. Thing is they were very docile until I added other female Haps.
Our dominant male colored up nicely starting around 5-6" and is 12"+ now 2-1/2 years since we got him at 1-1/2". The sub-dom male stayed female silver till 7-9" then colored right up and grew 2" almost overnight.
Great fish, you will never have a dull moment with them.
