Does Anyone Know What Kind Of Fish This Is?

Supposedly this fish is a tetra, but it doesn't look much like a tetra to me. Does anyone know what it is?

im no expert, but it looks like a Killifish to me...

I agree, maybe a type of pearlfish killifish or a type of goodeid.

Hmm, they told me it was a tetra at the pet store, but considering how little it looks like a tetra, they could have been wrong.

Here's another photo of it:

If it's a killifish, should it get along with my others? I have a snakeskin guppy, a pearl gourami, a black widow tetra, a swordtail, a pleco, a blue ram, a diamond tetra, and an x-ray tetra.
