starry blenny (beast)

this is my new starry blenny. a very interesting and entertaining fish. he is my new help for my hair algae problem. my foxface passed of unknown causes, it was fine and eating and active and then it was kinda still one night and dead the next morning. not sure what happened. water tested fine, all other fish, inverts, corals are all doing well, he just died! i moved my little redcrown algae blenny to another tank, he was no help with the hair algae. i did some research and was recommended to try a starry or lawnmower blenny so i picked up this guy and i didnt think i would like him as much as i do now. he is very active and curious and one of few fish that is not camera shy. i was wondering, has anyone had success with a starry blenny taking care of hair algae?
