Torch coral splitting?

Baseball#27 · Feb 10, 2019

So I'm confused on what my torch is doing if it's splitting or what. I got it 7 months ago and it's always done really well and loved my water. And I bought two of them and the other one is doing amazingly as always and my other torch and all my other corals are really really happy. But for the past few days he seems to have shrunken up a lot and I know corals aren't supposed to show skeleton when splitting but it's showing some skeleton down the middle of the coral and it looks like it's forming two heads but I'm not sure. My parameters are: salinity 1.025, temperature 78, Ph 8.3, alk 11, calcium 430, ammonia 0, nitrates 10, phosphates .02. And these parameters are usually very stable in my tank. Like I said everything else include the other torches are doing Perfect what leads me to think it might be splitting but who knows. Any thoughts on this?
