Does my coral need more light

[tylerblake04]

I have a biocube 16g with the factory lighting. I know if corals are reaching they need to be moved up in the tank. I’m new to saltwater and not sure how to tell when they really do need more light.

doesn't seem so. alveopora tend to extend, much like goniopora's.
