Okay my dad just bought a new Brain coral a multicolor brain looks like a Trachyphyllia geoffroyi. But i noticed our old brain same family just white is dieing and i don't want that to happen to the new one.. i am reading they like Calcium.. How do i feed them Calcium??? I attached a picture of the old brain. The picture i attached is a old picture when it was healthy. My other question is there any way i can nurse the brain back to health? I will go take pictures now and attach them in the next post.
