Since I started my aquarium almost a month ago I have found the need for a good reference book about fishes. After going to the local Boarders store and cruising thought their books I ended up finding nothing. I am looking for a simple yet informative book about freshwater fish only. Something with stats about each species of fish (pH, community or aggressive, water hardness, water temperature, habits, pictures). Most of the books I found have information on how to setup both saltwater and freshwater aquariums then only has 10 pages that talk about different species of fish. What books has anyone used with good information about freshwater fishes?
