Are they Neurergus crocatus? If so, their care is like that of other Neurergus species. They are not common in captivity but they have seen a substantial increase in numbers in recent years. They had a "bloom" many years ago, then nobody seemed able to breed them for what felt like forever but now they are back. Hopefully their numbers will continue to grow as they are a fascinating species.
How are you hoping to help, though? Breeding them in captivity does absolutely nothing to help wild populations. I don´t know of any reintroduction efforts and if there were any it is almost certain that captive animals from the hobby would be of no use. If you like the species, you can keep it, of course, and if you succeed in breeding them that will help the captive population but not the wild ones.
