Sorry for late reply , I'm pretty certain its a bump/scratch from the new pics , give him a few days it'll start to heal , try to cut down on feeding so less mess is created and do WC every 7 days Imo

Seeing some improvement today!
Only slight but it seems to be less cloudy.
Keeping up dosage of melafix every day.
Lights are left off.
And will reduce feeding.
Will hold off on the water changes.
