I have to wonder, when I log on and it says under general reef discussion, 174 viewing...its the same number of people viewing much of the time! Is it us same 174??? Just wondering

(where is the smiley peering at its computer???)
Why I really created this thread was I was shopping for books and I came across a book that seems very similar to Scott W. Michaels Marine Fishes: 500 Essential to know Species. here is the link. is it the same book? an updated version? a new book containing only reef safe fishes? anyone know?
