This book is supposed to be a complete guide to care and breeding of over 100 catfish species. It ain't.
For example, Corydoras species (probably the most commonly kept catfish in the UK) barely get two pages (with a few glossy stock photos).
The book details the care of some species, but 100? Maybe 100 are mentioned in the text, but the majority aren't individually attended to.
As for breeding, this is only cursorily covered and there is scant (if any) information about raising fry. There is a suggestion to patronise a couple of websites, but that's just not good enough. I'm right here on the internet - if I wanted a link to a web site, I'd use Google instead of buying a book.
Very disappointing and nowhere near the book that the title claims it is. Very disappointing.
