Hi everyone,
Hope someone can help. Yesterday, most of my corals seemed to be sulking, all of a sudden. Zoas are swollen and closed, some expelling brown stuff, candy cane crimpled and green policopora (spelling) not extending, mushrooms seriously shriveled and retracted. Some fat zoas look like someone's tied a string around the base with swollen heads.
Two things that are different than normal in my tank:
1) harlequin shrimp finally got hold of the starfish and ate one leg off. Two legs still stuck on the glass, so I am not sure that it is dead yet. He's been chowing for 5 days on the one leg;
2) I have a blue led strip light (approx 12w) as a moonlight in my tank in the front (on 1 hour before and after main lights are on). When it is on, it gives a nice blue effect in the tank. I thought it would be nice to add a second one in the middle of the tank that is on with the main 4 T5 lights. So, I bought another one and had it running with main lights the day before.
Now, can it be that I have a nitrate spike due to the possible dead starfish or are the corals stressed due to this new blue led light?
I have removed the led yesterday, and added some SeaGel today. The zoas that are expelling, only started doing it now.
Ps- this evening the corals are overall looking better, but still far from where they were.
Appeciate any help. Will post pics seperately.
