That said, I'm sure you're trying to give the fish the best home you can. If I recall, you have a 55 gallon with some mixed African cichlids, including several Mbuna. You might be able to get by with this for a while, but it is very unlikely your fish will coexist harmoniously once they grow and mature. The oscar itself should eventually get large enough to be the only fish in a 55 gallon (although I prefer to see them in 75 gallons at a minimum). Unless you have several other tanks at the ready, you'll probably want to consider rehoming some of these fish before they mature and kill each other.
+1 I agree with this 100%! The only thing is, I highly doubt he was born with one eye. If the oscars are housed where this one was bought anything like the ones where I am, his eye was probably torn out. Most places here that aren't professional with fish keep their oscars mixed in with Africans and those aggressive algae eaters(Chinese, Siamese ?) I just find it too odd for a fish like that not to be culled.
