I only have the first two Walls books that you mentioned, MTUPup. They are both definitely pretty outdated. I was laughing the other day when it said Azureus are rare in the hobby.

Does anyone know about this book, Poison Frogs: Professional Breeder's Series by Henkel and Schmidt?

Here's a link to it. Is it worth picking up?

Yes....that's a decent book worth owning, especially at a good price.

Well it looks like they have it at $47 after adding shipping. Would you call that a good price?

yeah.....I'd spring fer it if under $50.00.....

Before I buy a book I check it out at my local library to be sure it is worth the money.
Typically these books are not on the shelves but I put a request in for an inter library loan and typically get it within a few days.
Just a thought.

Good idea Beth. I work down the street from the big downtown library here in Sacramento. I bet they'd have it or I could get it from the UC Davis library.
