OK, I am probably overreacting, but I have to ask. Below is a rock of Green Star Polyps. You will notice that I capitalize the name of the coral in blatant disregard of proper english. But that is alright. Corals are that cool. Anyway, half the rock is not responding. I have moved the rock, but the level WRT the lighting is the same. A few days ago I caught the hermit crab on the rock. He may have been grazing. The polyps look intact, just not perky. Current pic is below. I have yet to do params. I just thought of it. I am going to post without and do them later. Thoughts? TIA. John. Edit: A week ago my params were good. Edit: See that aphasia to the right? It is a big one that just popped up. Any natural remedies I can use to spot kill it tomorrow without taking out the GSPs?
