Clownfish cloudy eye

[Jordan C]

Hey everyone I've had my two baby black onyx clowns for almost 2 months now. They are both doing awesome. They eat like pigs and look very healthy. Well yesterday I noticed on one of them that half of its eye was foggy or cloudy. He doesn't look or act sick. Now theses two do get into it quite a bit I guess trying to decide whose gonna be male and female. Could it be just an injury or possibly the start of some sort of bacterial infection? And these two clowns are the only fish in my tank. Thanks for the help
