Sick Pineapple Coral

So we purchased a pineapple coral and when we got home he was a bit stressed and had two white bleachish spots. He also had a couple cracks that I didn't notice in the store. Now out of one of the cracks he has a weird tale thing. He has been in the tank about a month now and the beached spots are not growing and the rest of him seems to be doing really well. I would appreciate any advice or knowledge you may have with such situations. Thanks

P.S. if someone could inform me on how to add a photo I will post one

 

Unfortunately I am new and dont know much about sick corals. But I do know how to post a photo...

Goodluck with your coral!

if I had to guess I would say that is an algae. But not close to sure about that
