what does my fish have? bacterial? fungal? + what meds into QT

[deadmanh]

I have a Regal Angel in QT with two other fish. He has a patch of white on the bottom of his tail, and two tiny patches on his top fin. Does not look like ich, because I have run into that before.

Do the other fish have to be treated as well when they are not showing any signs? All fish are eating well: Frozen Mysis, Spectrum Pellets, Hikari Pellets.


Before going into QT they all had a 15 min freshwater bath with Methylene Blue... Now what ever medication I use, do I put it straight into the QT? - then it becomes a hospital tank. What happens to the bacteria responsible for the nitrogen cycle. OR do I just dip the fish and keep meds out of the QT?

here are pictures......

Thanks In Advance,
Danny
