A very good affordable book is POINSON FROGS Professional Breeders Series. W. Schmidt and F.W. Henkel. You can get this from Saurian or Black Jungle or check the link below.
There is supposed to be a bigger and more complete book, that was supposed to be published in 2005, but no one in the U.S. has been able to get it yet, by the same people with additions by others, including veterinary care. It will probably run around $150.00. POISON FROGS-Biology, Species and Captive Husbandry.
