Mistaken Identity?

[TeeBee]

Hi, I’m kinda new to the hobby. I got six Pristella tetras from a shop, or at least thats what they said at the shop. I now reckon one of the six is *not* a Pristella and I feel bad for the fishy, but I can't get it friends if I don’t know what kind it is. Can someone please confirm what kind this fishy is.

Looks like a flame tetra (hyohessobrycon flammeus). But I'm not sure about the color for the color of this fish is less red. But that could just be the lighting.

Thanks. Now I just need to find the little guy some friends. And yes I’m not an expert photographer plus I think its a bit stressed being all alone among the other fish

It is assuredly very stressed. All tetras are shoaling fish, requiring a group, and the group should be around 10(or more, but not fewer) of each species. You haven't given the tank size, nor the other fish you may have, but you should get more Pristella to make a group of 10+. Then consider the Flame Tetra which also needs 10, and decide if you want both, or if you don't have room for both return the Flame as it will never be happy alone. And keeping shoaling fish in smaller groups increases their aggression and other detriments.
