My clownfish seemed to go after him the first day but now everybody minds their own business. I plan on adding a Coral Beauty next and that will be the last fish in there. I like the Royal Gramma because the colors fade together, instead of having that definitive line. Does anybody know about a Knobby star? I can't seem to find much on them and the pictures that I do find don't look like the one that I got. I will get a pic of mine and post when I have some time. (when I am not at work

) I would hate to take the fish back, besides trying to catch it, my wife is so proud of herself for getting the fish on her own, and she is starting to show interest in my tanks.
