duncan polpys coming off!

jrod11 · 11/06/2009, 09:23 PM

Hi everyone,
i'm struggling with my duncan colony at the moment.

the heads on my colony are falling off and i find one every day on the sand bed next to it. Is it getting too much flow? I tested for nitrates/nitrites and everything was fine.

Any suggestions?

Lots of possibilities here.
Duncans don't like being blasted but ejecting heads is a last-ditch attempt for it to survive.
Is this a new coral for you or was it doing well in your tank until recently?
How old is your tank?
Are you testing your alkalinity, calcium, pH?
What is your water temp?
Duncans do best when fed, are you feeding it?

the duncans have been in my tank for almost a year. alk and calc are in check. havent been feeding as much lately,i'll start feeding. It was weird because they didnt show any signs of stress and then just started falling off.

should i move them to less flow? i always thought that they liked a decent amount of flow?
