FOUR FOR A DOLLAR tetras?

[ledieudufromage]

Hey,

I saw guppy tank at my LFS FULL of what looked like tetra fry. They are yellow with red fins and a black spot on their tail. They look really similar to Silvertip Tetras http://www.aquaticcommunity.com/fish/silvertiptetra.php but with red, less black, and fins that look like Pristella tetras http://www.tropicalfishandaquariums.com/Tetras/PristellaTetra3.jpg

I bought them all. It has been two weeks and they are almost large enough to photograph. I'm quite sure they are tetras now. They are starting to school. Once they get large enough I'll send pictures.

Does anyone know what they might be?

I thought I was pretty knowledgeable about Tetras, but I can't think of anything that looks like what you have described. I would be very interested in seeing those pictures.
