hopping yellow tang

[kui loach]

My yellow tang hopped out of the tank. Found him on the ground. Don't know how long he was there. Put him back in the tank. He is alive and eating but has white spots over his eyes and seems to have trouble seeing. Hope he gets better. he is lucky. Question: If I put a glass lid on my tank to conserve water and keep fish in, will this prevent enough lite for the coral that I have *brain, trumpet, mushroom, feathery? Will the white spots go away on the eyes of my fish?

I would not put glass on the top. get some egg crate, this allows the tank to "breath" covering the tank will decrease the gas exchange in the tank
