That's a tough question to answer, since I'm not aware of any hobbyists or companies that have produced a surviving captive generation yet. I've only gotten larvae to transform once, and they were slaughtered straight away by other small crustaceans in the tank. My hypothesis has been that once larvae exist, a system similar to what works for cleaner family shrimp would have reasonable success (there's a book on that called something like "How to raise and Train Your Peppermint Shrimp"). Of course, I haven't had success with shrimp larvae yet either lol. Even those are pretty tricky without a lot of resources to devote to the process (money, multiple tanks, and lots of space). With hermits, getting them to actually pair up and produce larvae seems to be the bigger obstical.
