something youre not telling us about your fish keeping methods?
I´m just kidding, i´ve had fish that were missing an eye before and they live perfectly normal lives, but ive only had a fully blind fish once and sadly he didnt last too long, just refused to eat even when I put it near his face.
out of interest how long would you say the fish was alive in the LFS before you brought it home? cause if its survived in an LFS blind im sure it can do it in a tank on its own.
Don't know, at least 2-3 months. i just reset my 30 and they were dirt cheap so i got them to cycle the tank. whenever food enters the tank they just skim along the top looking for food, then after 5 minutes they start acting like cories, picking at everything in the gravel.
also they are all astyanax mexicanus fasinatus...
