1 inch?

at what ever size you want to do it at...they are like cockroaches
 
i think the question is worded wrong lol i was wanting to know how long it takes them to grow to an inch. PS its my fault its worded wrong i had my wife post this while i was at work and i didn't word it correctly because i was busy painting or doing cut in or something
 
You can transfer as soon as they are free swimming if you use a large soft net, but don't lift them from the water in the net. use a small cup or a big spoon to gather them from the net under the waters surface.

And it can vary on how fast they grow. If you power feed them they will grow very fast.
 
It will be dependent on your feeding routine and quality of water.
