Angelfish by B. Walker (1974)

Angelfish are probably the most recognized fish by non-fish keepers. They come in a range of color and looks. Angelfish should not be a mystery to keep. This is general no non-sense approach to keeping and breeding these fish. It explains how to raise live foods like brine shrimps to feed the baby. It is illustrated with many photos some are color. It is reasonable priced book. I think you can find it for less $10. It is published by Tropical Fish Hobbyst.
