Toxic Pinwheel Duncan

[dflightx]

Its my first reef tank, had it for about 3 months now and one of the first corals i put was a duncan. Since then its been doing great, feeding it with mysis shrimp or reef roids, even started tiny pups on the base of the frag. Was also consistent on water change and parameters.
The only change i’ve done was feeding the tank with live Phytoplankton that i got from TSA, then the next day it just shrink down, and its been 3 days that it haven’t opened up so I dont know what’s wrong with it.

Hi

If other corals are doing fine I would wait for other 2 o 3 days. If it doesn't open I would do a 50% water change to remove anything that may be bothering him.
