I'm book freak and find it so much easier to read from them then the computer at times.
I just got (what appears to be),
imo, a very good book:
The Marine Fish Health & Feeding Handbook by Bob Goemans & Lance Ichinotsubo. Copy right is 2008 (so the research should be up to date). It covers a lot of info on maintaining good health;
details on foods and feeding, illnesses (identifies and gives treatments), treatment protocols, medication cautions; acclimating... great pics with specifics literally pointed out
with arrows! Very easy to read and follow. Its presentation is different than most in that it very clearly wants to reader to fully understand health & illness and how to maintain thriving species. It also references resources for further info and/or products.
Hope this helps
