I second what Gary said. At one time discussion boards such as reefcentral were nonexistent the only way to learn was purchasing books or magazine subscribtions.
Most were dated or gave you a 1 page article ,waiting a month for another article.
Moes book and writings were one of the few worth reading,and man how I'd long for the days of Aquarium Frontiers when it was in paperback format.
Worth mentioning is another of his books Breeding the orchid dottyback held to a high standard by many of those that write articles for online magazines.It is good to see he got recognition for his work.Very underated IMO.I have the book you mentioned but not the other but its on my list to own someday.
