I have a large colony of Duncan that came from Jendub about 1.5 years ago. All has been great until a few day ago. The heads have been closed for 3 days now. The rest of the tanks is great with no problems at all.

Has anyone had a similar experience?

Best regards,

U can try moving it to a different area in the tank. Low Flow, Med/high lighting.

My colony has been closed for a month after being wide open for a yr- why, I do not know?

Hmmm....what are your water parameters and when was the last time you changed your lights? I would start there to find out the source of it's unhappiness and go from there.

mine tend to close up towards the end of the day...I have them high in the tank directly under 250 watt halides...they have grown from 1 head to approx 20 in less than a year...

have you tried feeding it to stimulate it to open again?

This colony is ~ 60 heads and has been close to thelighting since I purchased it ove 1.5 years ago. /most times it closes at night to reopen in the AM. I feed the tank daily si teasing it out is not an option that is not being tried. As for params, all right down the middle on all levels with .15N3 tops

Thanks for everyones input!

Are you around all day to see that the heads are not opening at all?

All is good now, for some reason they closed for about a week and came back to normal......???

Mine did the same thing, they suddenly closed for about a week without any reasons, then reopened?
