Only a handful of people have ever successfully done it as far as I'm aware, it's not that easy. However unlike L. amboinensis which has reportedly needed 120+ days to settle, L. debelius is closer to 60+ days which is more similar to its peppermint cousins at 40-50 days. I have gotten peppermints to the final stage a few times, but they don't settle for me. Sexy shrimp has been better documented in hobby circles.
I have that book, and it's quite outdated but has some decent nuggets of information - though most of it is disseminated on the internet now.
Most important for the larvae is that they are constantly able to eat, they require decent food-density in the water column. If you can account for that and the resulting clean up, it is probably doable along with discipline to keep up lol. Attached is a scientific paper that details their culture.
