So I picked up a male ruby red dragonet about 2 ish weeks ago. I have since gotten him weened onto diced frozen mysis and he eats very well. My primary question is how do i go about QTing this guy? I am very big on QT, all my fish go through typically 76 day process (minimum) and corals and inverts about 2 weeks. As of now there are no meds in this tank and I do not see anything to be concerned about externally, but I'd rather be on the safer side and treat proactively. I was going to just do some sort of basic treatment for external parasites for 2-3 weeks, but do have to find a copper alternative. (He is also sharing the tank with an Atlantic sailfin blenny, which also is eating, VERY friendly, and appears to be in good health as well.)
