Where to catch Zealous in Scarlet and Purple Pokémon

Zealous is a solitary and exclusive cave inhabitant of Scarlet, so you will have to wait patiently for it to appear.
It is only in the northern half of Pale, so you will not see any on the way to Alford;
The caves at the base of the glazed mountain are your best bet.
If you only see Dan, you will want to capture it instead, especially because it has a broader territory.
Purple players will have to change for Dan and evolve it to get the three Pokédex entries.

How to evolve to Zealous in Scarlet and Purple Pokémon

Zealous evolves to Hydration at level 64, without special tricks that make you stumble;
Surprisingly, this is only 14 levels after Dan evolves at level 50. Train using the Lets Go mode and a Lucky Egg will save time for Dan or Zealous evolving to such a high level.
In general, Hydration weaknesses can overcome their strengths: a Fairy X4 weakness is easy to exploit, Levitar is fine, but there are multiple skills that would be a great improvement.
Iron Jugular better covers their weaknesses because it is part of Flying and Quark Drive means a great impulse of Special Attack.
