zemuron,
I have never heard of or seen any specimen from Australia; it is recorded from Cebu (Philippines, rarely imported), Sulawesi (sometimes imported) and Bali (photo record), both Indonesia, Papua New Guinea (described based upon specimens from PNG), and Vanuatu (sometimes imported) at present.
Rudie Kuiter & Helmut Debelius' Atlas (2006) narrates that it comes also from Coral Sea but it seems to me PNG and Vanuatu.
A friend of mine in Australia will import and export fishes from Vanuatu on occasion; it is natural that they will show pylei in their lists for sale.
YoungLe,
Yes, I agree at these sizes. Thank you.
