Wow, that's a tough ???. There are many and it depends on where you are starting from. If you are a total Newbe, the best advice I can give is to post a new thread here and ask the general membership what books they recommend for Newbies.
If you are asking me what books are good for learning the coral fragging business and you are not a newbie, then I'd highly recommend Anthony Calfo's
"Book of Coral Propagation". You can get it direct from the author at
his website . He'll autograph it for you. (A nice touch)
You would want to have Eric Broneman's book
"Aquarium Corals, Selection, Husbandry and Natural History". There are others. You could pose that question on a new post here as well.
These will get you started. Remember, learning is a life long adventure. I've been strictly saltwater for thirty years and I learn something new everyday. Ask, seek out information, read constantly. If you have that kind of passion this is a worthy profession. If you are haphazard or wishing, it won't happen. You've got to have passion for whatever you do in this endeavor.
Oh by the way did I mention a MILLION DOLLARS would be nice too.

If you want to see what I'm in the process of building go to my web site,
The Cultured Reef. If you'd like to be updated as to our progress, please join the "Members Only Club" and be sure to confirm your membership by clicking on the link that is automatically e-mailed to you. And if you have time sign the guest book and put a pin on our map to show your location in the US. That sounds like a lot but it's all quite easy.
If you have questions you'll find our toll free number on the web site, give me a call.
Good luck.
