Yes, don't allow your parameters to shift drastically or these puppies will crash like a rock. In the right light, they are stunning rich in color. There are many variation of this polyp. Some with different eyes, rings etc, but they are all very pretty, I mean very pretty. I hope they grow well for you as they are simply gorgeous if you can get them to cover a wide 4 or 5 inch rock.
I had 5 that grew to a nice colony of 20, then one day, my yellow tang ate them with a passion. I lost every single one of them. I wish you the best with them.
