There are several people who have raised cleaners, there is an article from an UK site, that details how to do it.
Can't get link to work, but do google search for U.K. reefs.com or just search cleaner shrimp breeding, there are also references on wet web of people just getting lucky and getting and having young survive, mine breed every few weeks and I have gotten 1/2 inch juv of Lysmata garbhami but they get eaten within a few days of being seen.
Here is a photo of the larvae just after being released.
Don't have the tank space to try to raise any larvae, I also get my blue stripe and red striped pipes to breed, and every once in a while I see larger fry, but they never make it to adult hood, too many other animals that can prey on a 1/2 inch juv.
