How do you know if coral needs more light

Started a candy cane on the sand bed. Its under LEDs. What are some indications it would need to go up higher?

I dropped a rock on them yesterday so they're still a little ****ed. But if they look good there, I will leave them.

I'd be angry too if you dropped a rock on me. Seriously though, the corals look great (actually really great) and I'd leave them where they are.
