I recently got offa amazon 2 books with detailed info on bettas. 1. Animal Planet Aquarium Care for Bettas by David Boruchowitz and 2. Bettas by Ph.D Robert J Goldstien. Amazon is cheaper than the ones at Petco ( $12 a book!!!?? ) The first one has loads of pretty photos and many tips on bettas, however, the 2nd one is mostly breeding/genetics but still awesome. Im getting the full version of that one at Petsmart :) I have the shortened version which strangely has the same fish on the animal planet book.... :/
any other great betta books out there?
