Welcome to the forum.

A clearer picture or video would help if you can get one. But from what I can see, it looks like something bit him rather badly. What else is in the tank?

I have a suckermouth catfish and a dojo loach and a Bala shark and a molly

Maybe some decor that has rough edges ?

Do you give additional food to your Pleco ? Out of hunger they can try to feed on the slime coat of other fishes.

And he seems to be much bigger than your RTS. This could be a possibility.

That does look like an injury. So, no illness.
