Just took a look at my tank, and my plate is looking kinda funky. I've got two plates, the other one is sitting just a couple inches away and is fine. Every other coral is fine as well. His mouth is all ballooned up and sticking up significantly higher than normal. Almost like he's puckering up. And it looks like there's bubbles under his flesh around his mouth. Should I be worried, or perhaps did he just eat something a little sour? Thanks
