I knew the Care Forum members would come up trumps on missing eyes!
I brought some neon tetras home Tuesday night, and put them in the quarantine tank, and left the light off.
Yesterday morning I noticed that one is missing the right eye, but it appears well healed over.
The poor mite swims kinda funny, and likes to stay near cover of ornaments and the sponge filter, but seems to be getting enough food.
Yup, I will monitor, but not fret. Thanks for the reassurance of this thread!
