If it's in a group of six and avoids infection it should be okay, I have a one eyed rasbora caudimaculatus that is doing fine, I named her one-eyed Agnes
I would put him in quarantine so aggression issues don't happen and watch him closely. He will probably survive if it doesn't get infected. Maybe he got nipped at or got scared and hit a rock or something?
Sadly my gt got hold of him it was like it when I brought it but didn't notice until it was in my tank looked healed up. My gt was to much trouble got a few of my sd's so removed him. Back to a empty looking tank. 5 squeaking catfish and 4 sd in a 70 g tank
