Identify coral and possible problem

[reefnoob87]

Good morning all,
new to the hobby and forum. My wife stopped by the lfs and picked up some coral. I believe what she purchased was favities coral. It seems to be doing pretty well. Sweepers come out, color looks good, and I've been target feeding it twice a week. This morning I've woken up and it has a mound growing on it. Is this bad? Any help would be appreciated!

Is it the same color? Hard to identify with the blues on

Sorry, yes it is the same color. Hopefully this picture will help!

Looks to be a war coral. Which is a type of favites.

Thank you that's what I was leaning towards but needed confirmation. Any insight on the bump growing up on it?

It doesn't look bad, I'd keep an eye on it but I think it's probably ok, almost looks like where the original plug may have been but if you didn't notice it before then probably not the case
