Bronze Fry Questions

[DiddleBug]

I have 2 month old bronze fry and wondered how old/big they will have to be to spawn.  Also, how soon can you sex them?  Do the females have to be gravid before you can tell?  I can usually sex adults fine, so I know what to look for.

9 months to a year before they are able to spawn.

Doesn't stop them from trying.
Got a couple of three month olds that have started the "look at me, look at me". But it's more like kids figuring out boys and girls are different than courtship.
I do have to agree on the nine months of age though.
As for sexing, I rely on resting posture. Flat=male, nose up=female. My girl has just started this. One can also tell by the pelvic fins, but get mine to slow down enough to see.
