I have had a happy and growing alveopora for half a year, and suddenly it started to behave strange. Not extending much, leaving the "doors" where polyps sleep wide open. I am worried what is happening, I do not want it to die - it is a large and beautiful piece. It is in this state for a few days already, extending a little bit more during day, fully closing at night.
My parameters have been quite stable, Alk around 7.5, Calc 400, temp 78-79, Phosphates 0.05, Nitrates 5ppm. No changes in flow or lighting for many month.
I am not using filter sock so there is plenty of particles in the water column and I am dosing phyto as well.
Also, all the other corals are behaving normally, this is the only strange thing happening at the moment.
I would appreciate any idea what could be going on - and what should I do?
