What Tetra Fish Is This...?

[vti-chris]

I just bought 4 glow light tetras for my 35G tank and 4 tetras which i have never seen anywhere else.
I haven't taken pictures yet and the LFS doesn't know what kind they are.
They have thin long body,CLEAR(see through) and red tail.Anybody knows what they might be.
My male guppy takes them for guppies(females) and can't leave them alone.

Sound like bloodfins to me. According to Baensch they are hardy and can live for a decade or more if well cared for.
