They won't get along once the grouper gets some size on it...the smaller fish will become food. I kinda hate to mention it, but your tank (even at 200 gals) is a bit tight for a full-grown panther grouper. They reach about 20" in the wild, so count on about 16"+ for a healthy, well-fed captive specimen.
