I have a Green Lobophyllia for about 2 months, the first month when I bough it was looking healthy and no concerns, untill this month that I have noticed that there is red small spikes and my lobo is spreading apart from the other parts of the lobo, I keep my light on about 7 hours a day, should i be concerned and take action to try to fix it? (I also feed with brine shrimp)
