At least I'm pretty sure it's a tetra. Been googling all night but no luck so far...
I bought three black neons today. Or I thought I did... turns out I got two black neons and this guy - he's exactly the same shape and size, just with different markings. He's kinda smokey dark grey with a dark spot on the sides behind the eyes, and then getting darker as it moves toward the tail. Very nice looking fish! The picture doesn't do it justice. There's also a hint of red or orange on top of his eyes.
Any help with identifying this would be much appreciated!
