Xray Tetra Looks Larger Than Rest - What's Up?

Over the past few weeks I've noticed one of my xray tetras is quite large compared to all the others. It seems to be swimming around as normal, eating normally with the others and generally no signs of any problems. Apart from being larger, it doesn't look ill - or is it?

If I look at the fish from above the tank, it's definitely wider than the rest.

Anyone have any ideas? Photo taken earlier today ... not brilliant, a bit fuzzy!

Maybe it's just fatter or older!! Possibly pregnant?! Can't see any pic I'm afraid.

Sorry, here's the photo.

Thanks for replying anyway.

Fatter, LOL. Are you sure you didn't overfeed them?

It's an x-ray tetra, overfeeding would be visible

Oh yeah... I never thought of that. I'm not used to the 'see through' fishies.

Just looks well fed or possibly gravid to me...

However.... its not an Xray Tetra Its a Glowlight Tetra or something very similar...

This is an x ray tetra:

I agree with MBOU. That is what we call a Glowlight Tetra here in the U.S. Looks a bit overfed to me.
