I only really noticed what I believ is the HITH becasue of some white
thingys hanging off the oscars head coming from where those whitish
streaks are marked on the picture.

After adding salt (0.1% / 1000ppm) the next mroning they were gone but
the
whitish patches remain - visible from and upward angle catching the
lights
full on.



It is also possible that the whitish slimy patches are an increase in the
fish's slime coat in response to the salt.
Can't say for sure- is there actual erosion in any area?
