Duncan problem

[Uncle Morty]

Ok so I have three Duncan's two on one plug and one separate. All were doin great and would eat well. All of a sudden they all closed and won't open that much. They are three different colors and look all different. Any help would be great. All water tests show that all is well the only change was that I added this coral that was given to me any help identifying it would be great.

It looks like that candy cane is attacking the duncan............try to move them.

"DITTO" move them further apart. Also watch out for that nepthea. My old nepthea killed everything that it got neared to.

Some times they close for a few if they eat a lot.but check the tank at night you be suprised how far lps can extend when the feeders are out.

My Duncans retract at night, but my other LPS are monsters when the lights go out!

the green coral looks like a colt its a leather don't think its the problem duncans are very weak and lose most battles I would put it further away from the trumpet for sure. my duncans close even when a fish swims a little close try moving it and keep an eye out

Thanks all I have made a few adjustments. I moved the candy cane and trimmed back the leather. Lets see if they open again. Thanks again everybody

Matt when I got the coral I was told it was green nepthea, the big one I have in my tank would brush up against my frogspawn and piss it off and wouldn't open for days .

nepthea is nephthieade its the species name for a COLT or tree coral and it is a peaceful coral it would most definitely lost a battle against a frog spawn wich are very aggressive corals

nephtheidae is the correct spelling sorry

nephtheidae is the correct spelling sorry

Oh sorry I'm a product of public school cant spell and it maybe a peaceful coral but my frogspawn didn't think so....

Well thanks for everyone's input on this matter. So far one of three heads of Duncan's opened and seams like it made four baby heads under it. The one Duncan head that's close to the green coral is still closed but has vibrant colors so I'm hopeful that it will open. Ill try to post pics tonight. Thanks again every one.

Nepthea can have a pretty potent sting (for other corals). IMO, that's the culprit.
