Starry blenny biting other fish

I noticed the other day that the two biggest fish in my tank (pwder brown tand and mag. foxface) had these weird semi-circular matching maks on their sides. Bite marks, I was sure. I come home the past couple days, more of them. The only culprit with a mouth big enough is the newishly added starry blenny.


I thought these guys were supposed to be peaceful, but Interweb "research" has revealed other stories of bitey starry blennies. I paid $15 for him and a helluva lot more for the other two fish. Unless someone can tell me hell calm the heck down he's gotta go, no matter how cool I think he is.
