Blind Tetra?

[AlliSten]

I have 5 GloFish tetras (white skirts). I have 2 red ones. One perfectly normal black eyes, the second one however, his eyes are red. It reminds me of what Albino eyes would look like, but with him being a GloFish, not sure how that would show up. He definitely acts like he can't quite see right. Hides in the back, and it takes him quite awhile to come when he is being fed. I tried to get a picture, but he is hiding. I will try again when I feed them later. Is this even possible?
