Candycane Coral… crack…?

[anthonys8107]

Hey again Reef2Reef! Today I noticed something I’ve never seen before on my candycane coral. It appeared to have a grey crack on one of the heads. It looks weird in comparison to the rest of the coral. I don’t know if it’s starting to bleach or if it’s just a sign of growing like stretch marks. I’ve had it for a monthish and it’s grown a lot(started with 3 mouths, has 6 now). Just wondering if I should be concerned or not, thanks!
