This thread should help, there are links to some really good articles on breeding bristlenose and caring for the fry, as well as a couple of first-hand-experience posts describing their breeding behaviors.

But to answer your questions...

1. I don't know
2. Hard to say, there's too many factors involved
3. 1 male, 1-2 females
4. Yes

Butterfly

1. approx 2-2 1/2 inches
2. Depends on the BN species, water quality, food available
3. 1m/2f

Our regular bns were almost full sized when ready to breed. We put them in tank together and they bred within days. It takes a year or so to be full grown. Our last 2 babies are 2-2.5" big and our bns bred back in February.
