Books are invaluable to all fish owners, from beginner to advanced. Here are my top choices for books about Discus.
1. Discus Fish
Discus are challenging fish to care for. This little book is a must for any new Discus owner to read. It covers the proper habitat for Discus, filtration and water parameter needs, breeding how-to, and disease diagnosis and treatment. Although there are not a lot of Discus photos, you can't buy a better reference book for several times the price.
2. The Proper Care of Discus
Covers all the important basics to successfully set up a Discus aquarium, as well as feed and breed them. Covers virtually everything, however information on disease diagnosis and treatment scant. Never the less, it's a good book for the price.
