Exactly. Neon tetra disease is no joke. Look for fading colors or curved spines. Once it's in the tank, it's hard to stop.

Good call. Just monitor the Embers at first, sometimes they can be a bit nippy if underfed.

Neon tetras thrive in soft, slightly acidic water, so your pH is good. Keep nitrates below 20 ppm, they're sensitive. For tankmates, avoid anything aggressive. Ember tetras or Corydoras work well. Feed them micro pellets or crushed flakes twice a day, small portions.
