There are some specific books on reef keeping that has chapters on fish and their challenges. Reef fishes Vol 1 as one example by Scott Michael. Bob Fenner has a couple books relates to butterflies, tangs, etc. If you are looking for an actual list, diets, and other meta data then no, probably not readily available today.
Books are always nice to have and a life long reference but these days not that cheap unless you can find them used. Even then. Searches are ideal but just be aware that you may end up with conflicting opinions. When that happens the onus is on the hobbyist to do more research and then come up with their own conclusions.
Not to trivialize what expert means one thing that always stands out is the source of product. Collection, handling along the supply chain, isolation, quarantine, etc. Expert may mean food requirement(s), may require display maturity (sponges, algae, pods, etc), or it may mean temperature. A lot of variables.
Anyway Scott Michael, Fenner, few other authors have some amazing books that may help and will serve you well with your time in the hobby. Otherwise search the 'net and do your best to vet the results. You will see a pretty good pattern before you know it on who is giving the advice and the quality of it.
All the best.
