Question about Tuka Anthias

[Oilers]

I was in BA checking out the maxi mini anenome and I noticed that they have the Tuka Anthias in stock as well. They are very pretty, I tell ya. However, the person at BA told me they are not easy to keep since they don't eat much and therefore tend to starve to death. I am wondering if anybody has been successful with them? What kind of food do you feed them? I would like to get one but I want to make sure they have a good chance of survival. Thanks.
