HELP! Whats up with my candy cane?

[Kevlar-0986]

I noticed the last few days my candcane coral has begun to tear in the middle of its body it eats very healthy never thought twice about it being not happy but all of a sudden this happened.... has anyone seen this before, is this (Good or Bad).... I took the rock out and smelled him but he smells the same as the rest of the rock not foul and pungent like some corals that have died.

My water parameters are as follows.

PH 8.2
Ammonia 0
Nitrite 0
Nitrate 10
