NIger trigger with pop eye

[daniella3d]

Few days ago I bought a niger trigger which has been in quarantine since then. It had some sort of cloudiness in the eye, but it looked more like internal. I thought it was from the netting and that it would pass but today his eye is sort of swollen and is poping out a little and it is larger than the other eye.

Should I treat it with antibiotics? I have kanamycin. The fish has a great appetite and still eat like a little pig, but I surely cannot let this go.

Will kanamycine work? especialy since he eats I can soak his food in kanamycine, will that work?

Can it be a parasite inside the eye causing the cloudiness? It sort of look like something reflecting the light inside the eye of the fish rather than a cloudiness on the lens outside the eye.
