Do lawmower blennies and tuxedo urchins compete for food?

Yes, I feed red and green nori sheets to my tang and rabbit fish and have tried putting sheets under rocks where the blenny goes but he is not interested. I haven't been having the lights on as much as I usually do as my chiller is having issues so I am hoping that once I get things sorted out he will have enough to eat again. There was a bunch of algae o nthe power head so I turned it off and he had a good feast on it.
