My Bicolor only nips coral if I'm late with the meals. In the morning a feed a cube of mysid and a cube of formula one. 12 hours later I feed two cubes of frozen mysid. He leaves my euphillias alone. I don't have a whole lot of SPS, just star polyps, xenia, zoanthids, and a green slimer.

He only nips at the star polyps and green slimer but not super often. I keep him fed.
