It depends..lol...based on some reading i did last night on some JP sites there has been at least some type of restrictions on them since 13 Apr 1989. Although at time they were known as not known as D. Pulcher, but instead as Micrloepis. So probably a restriction on the collection point? In more recent years it seems that they either strongly enforce the old restriction or exclusivly banned them from export.
On a somewhat positive note, i did read on those same sites that "Breeding is possible but highly difficult in Home aquaria." But again w/ no hard evidence, thats like anyone on this board saying the same thing.
How do you like the Books? Maybe you'll have better luck translating the "Datniode breeding guide" and can pass on some info to JD762.
