Those are snowflake clowns (ocellaris) bred in England. Live Aquaria has them from time to time as well as Sea In The City in Orloando Fl. I also think a place in Florida in Sebastian (not ORA) has now started breeding them (but I could be wrong).
Here is a thread from a while ago that has recently been brought back uphttp:

This is my pair some people do not like the looks of these clown but I think they are awesome.
