A 1-1.5" yellow and orange couple

the larger one is the femal or will be the female

 

[Icefire]

At what size it get determined? 1" = how many months old?

 

[GSMguy]

not known it is not about age as early as 6 months for spawning hard to guess.
the female will chase the male around a lil bit and he should shake/vibrate for her.
the female will grow faster than the male
