it is most likely just shedding. you can help by keeping the flow good around it or blasting it with a turkey baster. this is very common after they move into a new enviroment and will become less frequent as it becomes used to its new home.
just a note. be careful dosing too much extra food. most corals get what they need for food from good lighting.
