Matt_Wandell,
I agree with your post, however I think that I will attack the situation from a different perspective. How often is it that someone says, "I have a powder blue tang in a 10 gallon, he is scratching and has white spots. What should I do?" The educated, conscientious aquarist does not say, "Make sure you feed lots of garlic, so it doesn't get ich." The educated, conscientious aquarist says " Dude, for the life of this animal which you owe a debt of, at the very least, keep alive, get him into a bigger tank. This environment is not suited for him." Why should a dragonet not get the same treatment as a tang?
