Another Barron's book on tropical fish, this one specifically about live-bearers including swordtails (which aren't mentioned in the title). It describes the biology of live-bearing fish, how they reproduce, how they are selectively bred to create all the different colors and forms, and how to interpret some of their behavior. There's a profile section that shows lots of other live-bearing fish I wasn't familiar with like goodeids and halfbeaks. The usual care section and information about water quality, aquarium setup and so forth. Each chapter has a helpful question-answer section that addresses things like how to transport new fish a long distance, euthanize a fish that is fatally ill, or what to do with all the baby fish that you'll end up with (inevitable with these pets that readily breed in the community aquarium).
