About 3 months ago my green colony of zoos started closing up. Now it seems to be spreading to an orange colony right next to it.
I have another orange colony near it on another rock that is doing fine. All corals are open and look well.
I also have a sea squirt that is fully open and looks good.

Any ideas??? They are under 300wt MH 20k bulbs. But they Are kinda shaded.
