I've got an open brain coral that was a deep rust red colour on the outer flesh mantel and an almost luminous green inner area between the mouth and the outer mantel.
Although the coral seems to be quite healthy, with it "spitting" deep rust red coloured strands out of its mouth every 5 to 7 days, the outer rust red mantel is slowly turning a pale green colour.
Is this normal, or is it something to worry about? Does the colour change indicate some sort of deficeincy in either light or minerals?
TIA
