Will My Cory Be Ok

i cleaned my tank a few days ago and i noticed tht one of my corys was bleeding a little. now around where the cat was it has gone white

If you keep the water in check then he should heal up by him self.

Just wanted to point out that the substrate you have isn't ideal for corys... They like to rummage around and pointy sharp gravel will do his barbels damage, sand is better here.
Also makes me wonder how did he cut his self? What other fish do you have in the tank? Is he in a group?

i only have cories and two golden snails (my firsst thought was the golden snail bit him they bight hard)

Maybe he cut himself on the substrate, they spend most of their time on the bottom of the tank, if you only have corys then I would change over to sand.
He will heal though which is the main thing

It could be a heater burn, have you got a guard on it?
Keep the water pristine & keep an eye on it for signs of infection, does it look fuzzy?
