Gerry Allen has done a number of books (lots actually). Many are on damsel and clownfish (saltwater fish) but many are about freshwater fishes of Australia and the New Guinea region. He is also the man who discovered a number of species and went through and re-classified them all a few years ago. He has done another book recently but it is only about Australian native fishes. However, it gives you lots of info about freshwater fish besides rainbowfish, ie; gobies, gudgeons, saratoga, archerfish, grunters/ perch, etc. It is called:
