Hey again,
Had a friend from the LFS that was able to stop by and give me a second opinion. Unfortunately, mostly just confirmed what I had already seen for myself. His thoughts were:
Not velvet as velvet is very rapid and the fish would have been dead already (they are almost 3 weeks in QT with me).
Not ich as even though we see a couple white specs here and there, they would be much more affected by now. Possible bacteria/fungal thing that shouldnt be very harmless (the white dots).
Doesn't look like flukes as he checked the eyes (apparently you can see them if you look at the right angle, in the light).
So, pretty much back to square 1 - possibly something internal, not sure what we're dealing with. Could also be a possibility of stress/malnutrition (from not eating). He suggested I try blood worms, and a blood worm feeder which floats at the surface and slowly releases them (gives that grazing like effect which makes sense). I picked some frozen bloodworms up and purchased the feeder on amazon. We'll see how it goes for dinner.
While he was over the one fish did exhibit what looked to be some flashing and itching around the gills. However, then proceeded to resume normal behavior for quite a while. We did see a white stringy object floating through the water (hungry fish was checking to see if he wanted to eat it) - which could have been poop and could have meant internal parasite.
He also suggested trying a freshwater dip to drop whatever might be itching in the gills... However he said that every time he has tried a freshwater dip on his fish, the fish has always died.
Any insights you guys have would be welcome

This guy mostly focuses on coral (because of stuff like this), but definitely has way more experience and insight than i could offer on the situation. Hope it helps us towards resolution!
thanks,
danny
