Hello, I need some information about my coral. I think it is a toadstool coral but I am not sure. It was given to me as a gift from a friend about 2 months ago. This was my very first coral and it has been doing great. Polyps are extending and it seems really happy. A few days ago I noticed a small white spot but it's grown a little daily. It still seems healthy and polyps are fully extending still except for the edge where the white area is. Do I have cause for concern? Any help would be greatly appreciated. Current water info is below.
