Sounds like an internal parasite. Have you seen them poo lately? Are they still eating? I would try feeding a medicated food, and if that doesn't work, try some prazi-pro, or Jungle's parasite clear.

some of my fish's excrements are having the aspect like they'd have parasites,

and furthermore, theyr fins looks like rotting.

the white patches on the mouth and the finrot sound like a fungal infection. so some of your fish might have internal parasites, some might have a fungus, or both. jungle labs fungus eliminator is excellent and works well with their anti-parasite medicated food. Hopefully you have a quarantine tank because the fungus eliminator may well kill the beneficial bacteria in your tank.
