Quirky Duncan

[NuckChorris]

So I have two Duncan corals. One is happy and putting on new heads. The other is right beside it and has never been fully extended. I’ve had it for over 2 months. I previously had two colonies here with about 14 heads each. But a GFO reactor dropped my PO3 too fast and sadly I lost them.

But I was debating on moving this frag just to see if it would act different. What do you think?

Swap places and see.

Looking again, the flow can be wildly different.
One is next to the rock formation and one not. That can make a hugh difference.

So you think it’s not getting enough or too much? I’ve turned my power heads up and down just to see how it would react and it never fully extendeds. Just wouldn’t think it’d be a light issue

Maybe to much.
Swap them, see what happens.
I'm interested if the other opens up.
I've always had good luck with my LPS closer to rock faces.

Any resolution on this?

Nope. Moved it and it still opens but doesn’t fully extend. No clue why. Never had a Duncan that was this finicky.

If there not the same colony, perhaps they are just different.
Did that one ever open up more?

Duncan’s do vary in polyp length. I have one that the heads are just smaller it’s likely a younger colony and the tentacles are short (looks a lot like your smaller headed duncan), One that the heads are huge (easily exceed the size of a quarter) but have short tentacles and one with large quarter sized heads with tentacles so long they look like an RFA.

Mine are all located in proximity to one another. I use the fat head one as barometer. If it’s happy the rest seem to equally love life. Mine like to barely wiggle.
