I used to work at a Poopsmart and got to take home the 1 eyed fish every time. The goldfish would always, I'd assume, eat each other's eyes out during shipping, which I thought was strange, but sometimes you could see directly through their heads from socket to socket, and they would still be alive. Those would never last long though, but the one eyed cichlids were more advantageous, and you could hardly tell they had any disability. They almost always looked like one eye just didn't develop for some reason.
Anyway, I had a little one eyed blood parrot, which is already a pretty physically deformed creature having 2 eyes, and I ended up putting it in my 29 with my african leaf fish. I ended up naming him Fsh (fish without an "i" *badumCH*) and he was one of my favorites. He was pretty pugnacious, but since he couldn't bite because of the deformed mouth, the passive leaf fish was the perfect tankmate. He would like charge the leaf fish, but the leaf fish would just slink over him and around to his bad eye side where he would then pretend to be a leaf, and the parrot would feel victorious, or just forget there was a tankmate entirely and go back about his blood parrot business.
ANYWAY X2, one eyed cichlids are difficult to feed! I remember using tubifex worm cubes and pushing them on the side of the tank so the food was stationary, or directly hand feeding pellets to my blood parrot, so keeping him in a smaller tank until you get a feeding routine down is probably the best bet (otherwise you put food into a huge tank and there's a 50/50 shot the fish sees none of it and it goes right into the filter).
