Duncans not opening for weeks

[Floyd-]

I have a little 25G lagoon tank with mainly SPS and LPS. The duncans normally are fluffy and always open but for the past 2 weeks other than a small peek they have been closed most of the day. Nothing has changed in the tank and no other coral is close to them. Parameters are the same as they have been for the past year. Ive seen LPS be pouty before but this length of time is worrying me. All other coral are doing great and growing very fast with great polyp extension. Even my clove polyp corals are doing great!

I'd post a picture of the duncan, it will help people see what it is doing. Even though everything else is fine I'd post parameters as well

I can get pictures later. Parameters were
Temp-78f
salinity-35ppt
no3-3
po4-.12
cal-390

I dont test mag or anything else. I do have a hanna PH meter but never use it. My parameters have been near 0 no3 and .3 po4 with everything thriving. Not sure whats messing with this one coral in the tank.

Has something been bothering them? What about your lighting?

No other coral is really close to them. Lighting hasn't changed in almost 2 years since I setup the tank.

I heard that fish will pick at them. I don‘t know if that would cause them to stay closed for that long though

Here are some pictures from last night when I got home. This is the best they have looked in weeks. Normally they are fully retracted.
