... on a flame hawkfish and a whiteish mottling/film on baby blue tang. Neither of these "conditions" look like ich to me, but as always, I could be wrong. 
Both fish have been in QT since I got them on 12/13. This is day 24 of QT and day 15 of hypo treatment. 1.010. Water quality good. Both fish eating really well, not lethargic, the tang does tend to flash.
First, the details on the hawkfish: this little white what looks to be a parasite is on his left side. It's the only one. It's very difficult to get a good picture of it - I'm afraid it's just a blur and the best I can do:
The tang is about an inch and a half long. The condition I'm refering to doesn't show up no matter how much I tweak the contrast of the image. It's not fluffy or cottony. It doesn't look raised off the body and it doesn't look like salt, as I said, or ich. It only seems to be visible on the black palette marking. I would say it most closely resembles a scaling or flaking, but there are no flakes or scales coming off. Does that make sense? Could it just be a discoloration related to something other than disease or parasite?
I have some other medication I can use, but I'm hoping both of these things can be dealt with through the hypo and time in QT since medications really tend to mess with the pH. Otherwise, I have Praztastic, Paraside-D (25 mg), Formalin-3 and Marycyn 2. And copper. I'm about to do a 5 gallon water change - they're both in a 20 gal.
Any thoughts? I don't want to harm them more with needless medication, but I don't want them to get worse while I just wait for hypo to work.
