Hi guys!
my tank is preparing to fall asleep under blue lighting sunset schedule.
polyps retracted and noticed these blue marks on the skin. Coral is looking very good by day and growing well.
Therefore I’m not too worried, but anyone had a clue what this is? Maybe a biological concentration of something inside the coral?
