Help me ID these Payara / Saber Tooth Tetra

[jklopp]

Saw 4 of these at my LFS the other day for $29.99 and wanted to get some help identifying what kind of saber tooth tetra these are. I don't know how to tell the difference and figured i'd have the experts take a look. Sorry if the pictures are a little blurry.
