Faded neons

[Tl52505]

I just picked up a couple neon tetras and immediately noticed there color was way less vibrant compared to my other neons, could this be stress related, or could they just not be healthy. The fish with the circle around it is one that I already had and the ones in the background are the new ones

They might need time to settle in
They might be a different species
They might be sick
But probably the first one.

I think it is adapting / stress. Did you buy more than three?

Completely of topic (sorry) : I think to see a juvenile common pleco in the back. How big is the tank ?

That's quite normal when they enter a new environment. Just adjusting to the new environment. Nothing to be worried about.
