Ha yes I have a golden one too it is great but they hide alot. One of my regulars lives in the sump and he got into the skimmer section tonight. I tried to get him out but he pinched me so now he stays.
I've had a CBS for over 2 years now and I can confirm they are predators. It is definitely the boss among the inverts. It chases smaller fish. I used to have a Tanaka's Pigmy wrasse that was caught and eaten by the CBS within a week after I bought it. He was forgiven and given the time already served. About two weeks ago I bough a sand sifting starfish and 2 days later I notice the CBS eating a piece of the starfish leg. The starfish has not been seen since. Due to the amnesty the coral banded shrimp still lives but his file is thicker and thicker.
