Can You Identify My Tetras?

[Phishy25]

I have recently rehomed a few tropical fish from different people and I am now trying to identify them all. I had 4 blue neon tetras so I over time I have increased the number upto 10. However, I have noticed the orginal 4 are not the average neon tetras. They have a neon blue stripe through the middle and are approx 2" long. I thought they were cardinals to start with, but they have no red on them. They are a couple of years old so do they lose their colour? They happily swim with the neon tetras, who definately have red on them!

Tried to get a pic, but they are so fast they just blur. I googled blue tetras, but they dont look the same.

Mine are blue too. But if you look down on them at an angle, mine go greeny blue.

Definitely 'green' neons Paracheirodon simulans. Mine are blue too; though I suppose it's a greeny sort of blue. I have no idea why they're called green!
I think 'false neon' is a better common name for them
