It takes just as long to make BEL's as it does albino morphs, if you start with female albino VS male lesser.

Here's a loose timeline, I realize 18 months is young to breed females but they do and will(I have eggs in the inc from two females that bred at 18 months old).

Buy a hatchling male lesser(May 2011) and breed it to a normal(Nov 2011) and hold back female lesser that hatches in June 2012
Raise that female lesser 18 months(Nov 2013) and breed to the male lesser(Nov 2014) for hatchling BEL's in June 2014

OR

Buy a female hatchling albino(May 2011) and raise her to breed at 18 months old(Nov 2012)
and hold back male morph het(June 2013)
Breed that male morph het to mom(Nov 2013) for baby albino morphs (June) 2014

In the end it is what you want to see in your tubs, I've got both projects going and they each are exciting in their own right.
