Long term yes it isn't the best size tank for a coris (as I noted in my post ), however the OP wants a must have fish for a zoa/paly dominated tank and they are some of the best protectors of z's and p's and IMO a must have.
I agree, you can always move it once it grows too large but if you start with one individual about 3/4"-1" you will have a great friend of the zoa dominated tank for quite some time
