I have the Aqualog book and it is very good, but it isn't perfect, and you will find some information in there that contradicts other sources. For example, in the Aqualog book species like the green spotted puffers are referred to as good community fish. This seems to be because the author is a collector with hundreds of tanks, and simply moves out "difficult" fish, leaving the peaceful ones behind. This obviously doesn't work if its just you and your community tank.
It also tends to have the accent on large aquaria without much thought for decoration or aesthetics. There's much talk of leaving algae and cyanobacteria in the brackish water tanks because it looks realisitic; something I doubt very few people will do! I haven't found the feeding advice to be completely helpful, either; the author recommends mussel meat as the staple for all puffers, yet neither of my species (red-eye, red-tail puffers and a South American puffer) will touch the stuff. Finally, the bit on trimming teeth fails to mention sedating the fish first. It's a brave man who trims the beak of an adult puffer without sedating it, and I doubt it's even possible with the small ones!
On the other hand, it has an excellent section on identifying the species, and the comments on optimal water conditions, etc., are rock-solid. Recommended, but do look for second opinions on the husbandry topics.
