i think the best resource is the internet.... but if i have to pic a favorite hardcopy it is the one from Ivan Petrovicky (Aquarium Fish of the World - A Comprehensive Illustrated Guide to Over 500 Aquarium Fish). it's completely illustrated, so it may not fit the requirement of 'with pics'. the illustrators really capture the essence of each fish in lots of detail, and it's beautifully done.
i like to keep a small library of fish books, because, as some people point out, each book has different strengths and weaknesses.
