Guppy Fry Growth

[tropicalfish311]

Hey I have four four day old guppy fry and i was wondering when I can start giving them away to people and selling them.

I wait until they are about 2cm long in total, but purely for the reason that they'll be more robust and better capable of handling the stress involved with moving. It hasn't got much to do with anything else. I've moved day-old fry between different tanks within my house before.
