sorry no pictures. It has not opened up in at least 4 weeks maby even longer. It is also started to grow algae on the face of it. i have removed the algae but it starts to grow back. I dont get it. the coral looks fine and it is firm to the touch. It dosnt look or feel dead. It hasnt changed colors. It just hasnt opened up in a long time and is growing algae on it. I dont no my water parameters but thats one of my hardest corals everything els looks great. Im just wondering how long do i leave this coral in my tank before i give up on it?
