So we got a purple mushroom coral about 3 days ago. We put it in our tank and it opened up immediately. Now, since yesterday it has been kinda shrively and only partially open. Also it is turning from a purple to a darker purple with rusty red mixed in. It is in a lower flow area and has medium light due to being knida in a cave. Water paramaters are good. what could be causing this? Different lighting? It is under a 4 bulb t5 fixture.
