Dunken coral no luck

has anyone ever had any good luck with dunken coral. I never do. I have a very small colony and I can't get them to open at all. The frist 2 days after i got them they were fully open after that they closed up and have not reopen in 2 weeks now.

I have struggled with Duncan’s. Perhaps more than any other coral. It’s not that they die. I have had same issue as you. Sometimes they just don’t open. I had one closed for five weeks. I presently have three of them that I move around the tank. Funny thing is they don’t all like the same parameters or conditions. I have been unable to pinpoint if it’s flow,or lighting I have put them next to each other and in about five days. Only one opens Move them and a different one opens and the original closes. Presently I have two open and one closed. Closed one has been closed for three weeks. He will get moved until I find his happy place. Only trick is you need to leave them be for awhile once you move them. It takes time before the come out even in ideal situations
 
My Duncan has been super hardy and probably my fastest growing coral. I have had my nitrates at more than 60 at one point and now it's at 1.5 and still just as healthy. Flow or no flow. Exactly under the light or off with something shading it.

Yea no clue why mine won't open my water chemistry is dead on tank got med flow at the bottem and high at the top due to the bird nest corals at the top. There sitting say 30% off the bottem its about 75 par at there location. I am useing led lighting. the place I got them from are using the same kinds so the transition should not been to bad.
 
Mine seem to like the water a pinch dirtier. But I can’t pinpoint it. I just move them till they are happy
