Their bodies resemble Lobophyllia in many ways, but unlike lobos, they have a much more diverse color arrangement. I’ve seen them come in just about every color imaginable, and it is very common for them to have large bands of colors. Unfortunately, I don’t do very well with Symphyllia. As colorful and amazing as these corals are, they’re a no-go for me until I learn more about why they might be struggling in my system.
