My wife bought tetras near where she works about a week ago but we she didn't ask what they were. They are mainly a whiteish, silver colored and nearly transparent from just behind the gills back to their tail. They have a faint yellow strip on their fins and a faint orange or red tail. On 2 of them the tail is so faintly colored you almost can't tell that the tail has a tint until they turn the right way. They are very pretty. Any idea what kind these are? She hasn't been back to the store to ask them.
