Hammer coral tissue recession

[beehive124]

Hi all! I have another question about my hammer coral. So over the past 3 weeks my hammer has been flourishing. All my params are in check and everything is going great. I have noticed tissue recession at the very base of the coral. I have read that this is normal, and that the tissue will stop receeding after awhile. The piece of hammer I got was freshly fragged, so I’m wondering if the tissue is receeding to make room for new skeleton. Any help would be appreciated thanks :)
