In the 1960's this was the book to have. Over the years I accumulated others, but this was the one I came to rely on. I seem to remember that it was also one of the first to have a good percentage of colour illustrations, which sounds strange by today's standards, for a book on tropical fish!
As you would expect, it covers all aspects of keeping an aquarium, but is principally about freshwater tropicals. Out of the 480 pages, only the last 17 pages cover marine tropicals. (Thats the part I had completely forgotten about!). And it's the very last page that caught my attention! ........... Dragon Fish, indeed! - mmmm.
Be it Lion or Dragon, it's a nasty little sod, isn't it?
............. and I thought we had a nice community fish in our presence!
