I was checking on everything in my tank, as I do daily, and noticed one of my brain corals looked extremely swollen. I'm about 3 months into the hobby and only had this coral for a few weeks. But this is my 1st time noticing anything like this.
Is this normal or should I be concerned?
Unfortunately, I do not have a picture of it not swollen.
