Buadhai, is the full title Marine Fishes of Tropical Australia and South-East Asia [emphasis mine]? If so, I have had this book for many years, and I have to admit that I never crack it open any longer. While it appears to be very comprehensive with many times more fish per page than other guides, and while I may be able to confirm that a fish I'm familiar with is indeed the one in the book despite the fact that the illustration is very different, I just don't like the book much. For fish I'm uncertain of, I've found this book to be rather confusing. In many cases the images were painted from dead specimens, which means the identifying characteristics are no longer the same as in live animals. Furthermore, the focus is so very Australian (despite the mention of SE Asia in the title) that for me, when added to the problems with the illustrations, it's just too much to wade through and evaluate. I really hope you like it better than I do and that my objections are idiosyncratic!
