I found this book easy to understand, but as a beginner with bettas it didn't answer all my questions. It mostly covers aspects of breeding bettas with more general info interspersed. It did make me want to try breeding bettas however! I would suggest another more beginner book if you've never had bettas or are not going to breed them. I can't recommend any though, as this is the only one I have so far. I bought this one at the recommendation of the guy in the fish store.
