I just recently got a copy of the above from a charity shop,a good place to get yourself a small library of tropical aquariums and plant books. I agree about UKAPS as good as anything as it challenges and has all the aspects of modern Fishkeeping and the planted aquarium. That said I still likely pick up a Mills book to look up a fish.Those old books still have their place even though things have moved on example activated carbon,aged water etc.Now with up to date filtration carbon in your filter is more of an aid than a need to have. Plus modern day explorers are getting in once previous wild places previously impossible Ad Konings,Julian Dignall,Dennerle plant hunters discovering new habitats and plants,fish. My best new book at the moment Stuart Thraves Setting Up A Freshwater Aquarium good book for people coming into the hobby
