Its not corals that they would potentially go after, its the inverts. Shrimp, crabs, snails, worms etc would be the critters you'd need to be worried about.
The Yellow Coris' I have (2 of them) are both in tanks with everything listed above and have showed no signs of aggressiveness towards them. As the coris gets bigger, that may change but I would feel more comfortable with them in the tank and possibly (remotely) losing a shrimp at some point rather than having nudies eating up my prize zoos/palys etc.
I wouldn't be surprised if these things at spiders too since they go after pods as well.
