Dendro won't open

[socalmicskills]

After I got my Dendro from the LFS it was nice and open, all of the time. A couple of weeks later I installed a sump. I had a feeling it wouldn't be happy in it's old spot (med light, light flow) because the sump would create more flow there. I was right, it didnt' open again there. So I tried moving it all over the tank low to mid light and flow, still nothing. It hasn't opened in a week. It won't eat anything. It was doing so good before that, even starting to grow two more heads. Any ideas? I've tried feeding it even though it wasn't open, no luck. I've moved it completely into a shadow. Everytime I've moved it I left it for a day or so before trying again. Once in a while one or two tentacles would come out partially, but never staying out, it just stays tightened up the whole time. I've got a whisker (duncan's) coral that is doing fine and I got them both at the same time, didn't have to move the whisker though because it was on the opposite side of the increased flow.

Give it some time the shock of adding the sump couple place him into a brief dormant stage for his protection and natural way of combating natural selection in the oceans. Some corals (duncans included) can survive closed for a while until they settle in a new place, give it time and look for receding structure is what will tell the true health of your species.

still not opening?

[socalmicskills]

Still not opening. The tentacles have loosened up a bit they are raised a tad, but not open by any means. I can't really tell if there are any signs of degeneration. I don't see the heads on it that were starting to form before it all began. It seems like it is getting a very minor amount better by the day, but still looking really bad, hasn't eaten at all

the only thing you can do is just leave it and keep your water as consistent as possible (ie salinity, dKH, temperatures)

[socalmicskills]

That's exactly what I've been doing. And, guess what???? It finally ate last night. And today, the tentacles are all about 1/3 of the way out, it must be getting better. Woo Hoo, I definitely didn't want to lose this one, it's my favorite coral so far, it looked so awesome when it was all the way opened, and I dreamed of when it would grow into a large colony.

its funny how corals can be moody at times isnt it!

[socalmicskills]

I don't know if funny is the word, but I know what you mean. It has been eating regularly now, still hasn't opened all the way yet, but the heads on the sides look like they are coming back, so that's good.

We had a sun polyp corals that did not open for months until we realized that they only come out at night and dont need lots of lighting and in the wild they grow in turbulent darker areas of the reef. We started dropping in frozen Cycloppeze every other day and it started to come out with its tenticals.
