If it has grown out with the cories. Well fed and plenty of hiding places that the red wolf can't snake in there. There's a small chance it'll survive but I think it will likely go after them.
Even if the wolf doesn't "get them" in an attack and kill them outright, him nagging and nipping them and similar smaller injuries to a fish like a cory cat can definitely become infected fairly easily and then you have a completely new issue on your hands.... And a potential much bigger issue.
Nipped fish are prone to getting sick for a number of reasons. Just one of those slippery slopes. My opinion anyway.
