Not really in the sense you mean. All are basically similar in that they show you microscopic slides of the aflictions but no "live" fish specimens as a comparisson which can make it rather tough since the general references to each problem can be ambiguous. The key is to ID
a given affliction so that is where I would spend your efforts. Once properly ID
'd, treatment is easy to recommend and implement in most cases. I would just keep looking online at various reference sites in hopes of catching a few images. I'd ignore most of the additional info about how and why though, tends to be rather conflicting. About the best author to look for is Dr. E. J. Noga in terms of accuracy. There are a few sites that quote Shawn Prescott but I would just look at some of the available images and only lightly scan the articles.
Should I leave my main tank fallow for any certain period of time? It will at least be a few weeks while I have a new fish in my Q tank.
Sounds to me like you may have not ID
'd this problem correctly and I would err on the side of caution. As Quarryshark said, would be safest. I wouldn't beat yourself up about it though, some problems can be obvious but many more are quite dificult to pinpoint without a microscope..
It might also be an idea to figure out how this problem came about in the display tank and take steps to eliminate/prevent it in future.
