Have you started treating your fish? If so, how? Put salt in this new tank, heating.

Any help on how I can make sure he is alright would be very much appreciated, as well as if someone could answer these questions:
If it is ich or velvet, what are its chances of surviving? He is basically just resting on the bottom, I can see that he is breathing through his gills, he is also gulping with his mouth. His fins are contracted.
If it is not something extremely serious, what is the usual timetable for symptoms to become alleviated? And what is the best way to ensure that there is a proper concentration of bath salt in there, etc.
Pictures attached, and thank you all in advance!
