Query: incomplete information

This is a nice book to read if you are mildly interested in bredding tropical fishes. If you really want to do it, you will not find the specific information you may want to have in this book. For example, in breeding Betta Splendens the author suggests water temp and aquarium size. Unforunately, water quality may well be much more important. What is the recommended Ph? Water hardness and other chemical factors if properly reproduced as the fish experiences it in the wild will help in spawning the fish. This kind of lack of information repeats itself throughout the book. Luckily it is out of print so you won't have to suffer...
