Up to a few days ago my Duncans we’re really opened but since two/three days ago they have closed and remained like that
Any idea why??

From the looks of your rocks , it appears you have a mature system with healthy coraline growth. What's your nitrate and Phos? Alk?

In a mature system, bothered (like shrimp) or hungry, (nitrate and phosphate), asummin lighting has not changed.

All is good. Around 8.3.
Nitrates are highly, around 30 and phosphate is also higher, around .52 but they’ve been like that all along.
IM using the Red Sea NO3PO4x to reduce them slowly

I meant to say Alk is good

well, its not hungry with high nutrients like that. Anything else angry? Any shrimps or fish that may pick on it?

I have an infestation of asterism starfish that I’m trying to tackle with a harlequin shrimp I bought yesterday. I’m wondering if the starfish are bothering him

it seems whenever my duncan sulks for a week or so a bump for another head starts to form...
