I have one of these little guys in my tank right now. Actually, I also bought them at PetSmart and if I remember correctly, they were sold as Gold Von Rio Tetra, but I'm sure they are the same thing. I saw some of them swimming in a tank and noticed that several of them were missing their eyes. I asked what had happened and apparently when they got the fish in, they were placed in a tank with more aggressive fish who ate their eyes.

Anyway, I couldn't just not bring some of them home! I think I ended up getting 3 without eyes and one with eyes. The eyeless ones survived for quite a while. All that survives now is the one with eyes. He's been a hearty little fish who gets along very well with the other tetras in my tank. Good luck with yours!
