One of my Penguin tetras has developed this ( see picture )
The other eye is clear, he did have a problem with it a few weeks ago and I think this is the end result.
Is it quite possible that the poor bugger is blind in this eye?
It doesn't seem to affect him at all, feeding fine etc. The only thing is that he's quite jumpy if something comes past him on this side. Hence the assumption he's blind in this eye.

It is quite possible for a fish to lose an eye and live quite happily in an aquarium. In the wild they'd probably be picked off by a predator but there aren't any in an aquarium. As long as a one-eyed fish can find food, it will be fine.
Causes are usually physical damage (caught itself on some decor), the result of an infection, or fighting.
I once had a dragonscale betta which went blind. These bettas have extra thick scaling which is prone to growing over the eye. This is what happened to mine. One eye was completely covered; I don't know if he could see anything with that eye. The other eye had a tiny spot not covered. He managed to find his food and navigate round his tank with no problems.

Wow clever little betta.
It was more of a query rather than a concern.
He seems content enough, he's not being bullied by the rest of the shoal or pushed into isolation. :fishy1:
