| HIya RC, nope not at all my friend. Corals extend thier polyps at night for a variety of reason. the main one is that most preditors are asleep and thus wont eat thier polyps. Polyps are not the only place a coral has zoox, the zoox is all over the corals. Hmmmm back..hehehe
Edge I was refering to Danas statement. I do believe that actenics do provide lighting that a coral can use, just not alot of it.
