Time for breeding bristlenoses?

[Barracuda]

How long does it take for a common bristlenose to reach breeding maturity? Is it the same time for all bristlenose (albino and peppermints?)
Will they cross breed and produce fertile offspring?
Thanks

Also, is the growth rate the same?

commons 10-12mths
albino's 12-18mths
peppermints atleast 2 years, though 3-4 year olds have better spawns
orange spots about 2yrs aswell
