There are 400 questions: each has four possible answers that test your knowledge, tease your brain, and tickle your funny bone. The correct answers are on the reverse of each question page and they are loaded with information on marine fish, marine invertebrates, marine aquaristics, reef and sea - answers that teach you a lot about this fascinating hobby.
Although there isn't a million dollar prize, you could use this book to play "Who wants to be a Marine Biologist" or "Marine Aquarists trivia". Whether it is read as a source of information on the hobby or used as an entertaining exercise, it will leave you with a greater understanding of the reef, the sea, and the captive marine environment.
