We have seen both in person. The Flavoguttatus is a smaller anthia & we recently put 3 in the new reef tank at Bio-Reef. So far they are very shy but eating and are slowly starting to come out more.
We recently had a male with 2 females Pictillis in the store, very pretty fish & pretty easy to get to eat....sold quickly
The Asfur is a nice angel but I would be worried about putting a large angel in a reef tank, but I have heard of it being done. Depends on what you like more your corals or angels

In one of my reef tanks it is turning out that I like my angels more

So now I have to ask what kind of tank are you setting up????
