Pristine watercondition and the varied diet you feed should help heal HITH.
On your tiger i see sensorypits but no real HITH.
Mind you, these pits are normal!
like in this pic:



On the orange O it looks like someone took a tiny icespoon and scooped out an portion of skin.That's what HITH looks like, imo.

if you look at the pic of them scrapping you can see the hith on the bottom of gill plate and right above the eye on the tiger. thanks

Here's a helpfull article, and it comes down the same to the previously given advice.
