No problem It's a good interesting read and covers other species as well. I've purchased two other books on Horned frogs and they've been bad reads, outdated husbandry and more like a child's book than anything, so be careful if you purchase any others. That one I recommended is the only one directly on Horned frogs that is good that I know of IMO, however Frogs and Toads by Devin Edmonds includes their care but it's only a small section of the book, so not as in depth but otherwise good
