Three neon tetras not a good idea. Should be minimum six or eight.
The white looks to be one of three things;
Columnaris , Neon Tetra Disease or Lymphocystis.
Keep doing salt bath as it may help if it is columnaris.
Watch other fish .If the issue spreads to other fish I would consider removing them.
