Duncan looks weird and twisted

[Robin777]

Hey guys!
This morning when I came down my Duncan looked all weird and twisted as picture shows.
Moved those two hammers that’s above it to that location a few days ago but it should be enough distance for them not to bother the Duncan! Any thoughts?
Thanks!

He's not happy. If the only change was moving those other corals above him, then that's probably the issue. Duncans also do this when unhappy with water parameters, so check those as well. I'd give him a week or so and if he doesn't reopen then he or the other corals will need to be moved.

Thanks for replying! The parameters are good so nothing has really changed other than moving the hammers. But I haven’t seen any tentacles from them touching the Duncan, could it be some kind of chemical thing?

But I’ll leave them be for a week then and see!

Thanks man!

Look later with a flashlight when the lights are out and the feeder tentacles extend. Could be some stinging going on.
