Duncan corals

[Want to learn reefing]

My Duncan's keep closing for several days. I started with 6 heads and now have 12 . They're not huge but seem healthy most of the time. Any idea why they are closing up like this?

They are actually on a rock several inches above the sand my parameters are what you said except the mag is a little high.

It's not a good pic the lights are on night mode. Maybe I can get a better picture tomorrow

any little bugs on them upon inspection? Mine are super happy always and each head larger than a silver dollar

I haven't seen any pest on them. I've had a sail fin tang packing around them after I feed them.

They are about the size of a quarter when they open with some smaller heads beginning to grow

That could be enough to shut them down for a bit.

I have a small frag with two heads that was open looking great in my QT lagoon. Put them in my display and within a week they closed up and wouldn’t open up. Move them a few times to stronger flow or lighting. Every time I moved them they’d open up for a few days then close up again. So back in the lagoon they went and opened up within a day or so and stay open. They even grew a third head. Water perimeters are same as I use DT water for lagoon water changes. So after a month I moved them back to the DT. Two days later they’re closed up again. So then I start looking at a WiFi camera I have set up and found that my moorish idol is picking at them when I’m not around. Now they’re a permanent fixture in the lagoon tank.

Can anyone tell me what this is? I was examining my Duncan's and this pinkish gel was around the base and that critter was inside it

Pic is too blurry. What are we looking at there? It looks like a human organ.

It's a pinkish gel that grew around the base of my duncan and there seems to be some kind of animal almost a tiny octopus or something living in it. I cleaned it from the Duncan
