Someone gave me a duncan coral about three weeks ago but it will only open a tiny bit. I have it in a low flo low light area but it just doesn't seem happy. I have moved it around and no luck. My water params are good and when it was in my freinds tank it was open fully...what else do they need?

My guy isn't in heavy flow but he's in a fairly high light area. Seems to really like it. I would make sure noone else is touching it. They don't seem to like being in close proximity to other frags. Not sure beyond that. Maybe a pic would help?

Good luck,

Bill
Is a .6 gallon, LED-powered acro forest possible? We'll see.

Unlike their relatives ( tubastrea ) Duncans need light.
They also need REGULAR spot feedings per head a couple times a week.
Personally I wouldnt blast them with light.
This is because they are found in deep water. So I would assume they would achieve thier best under medium to low lighting conditions with medium to low flow.
They do suck up the calcium as well.

I put it low in the tank in the shade and it wouldn't come out at all...i have moved it around and it just doesn't want to come out...my calcium is good. I'm trying it kinda high in the tank now we'll see what happens.

Anyone one else have any experience with these?

mine has been doing the same thing for about a week and a half now. I need some answers also.

my setup is 150w over a 24G with 50-60x turnover..good water param's..tried it high low with more and less flow. it just doesnt like my tank.

Mattfox27...have u tested ur Nitrates or Phosphates? just wondering if you have anything detectible?

So i just checked on the duncan after moving him up to the top under higher lighting and a tiny bit of flow and he has opened up as much as i have seen so far...so maybe he needs high light that seems to be working...but he still isn't opened all the way...hopefully tomorrow he will be in his new spot during a full photoperiod and open up all the way. I hope so becasue i have never seen him open since i bought him...I will keep ya posted.

My duncan is about 6-8 inches deep, under 150w metal halide + 48w actinic. Pretty decent flow, too. I spot feed him mysis and cyclopeeze every day, but I feed spot feed all my corals daily because it's fun and because I can. I also feed phytoplankton and golden pearls daily to the entire tank, and dose with B-Ionic to keep KH/Calcium up.

Salinity: 35ppt
Calcium: 440
KH: 9.5
Temp: 79.5
Ammonia: 0
Nitrates: 0

Mine grows like crazy...new polyp every couple weeks.

Duncans can handle quite a bit of water movement as long as it isn't direct. I also spot feed mine as much as possible and have seen tremendous growth. I've only had it for a month or two and the single baby head I have has tripled in size and should probably split soon (I hope).

Also what good is a thread on duncans with no pics???

should i keep moving it around until it finds a spot it likes? or do i just have a bad one? I mean should it do well pretty much anywhere in the tank? When it was sold to me i was told that its sooo hardy it will thrive anywhere, you cant kill this thing...but so far its the most sensitive coral i have ever owned.

also theres nothing too see on my duncan i can post a picture but all it would be is shriveled up tube...LOL

Hey Guys - 

 

Here are a few pictures of my Duncan. I took one before I fed it and after I fed it. 

 

I feed it once per week at the moment.

While they will eat and enjoy eating, feeding is not necessary. I have a duncan colony my clowns use as their host and I don't feed it all. Mainly because it's big enough already and I'm trying to slow down the growth.

lol. I use my duncan as a place to distract my cbs so that I can feed my Sun coral.

They can handle flow and light as long as they slowly acclimated to the new conditons. In high flow they get really long tentacles.

 

Feeding it is what got mine to open up.

I have mine towards the top in a Biocube 29 HQI. It get's a fair amount of light and medium flow.  It started out as a single head maybe 6 months ago and now it has about 7 full sized heads. I feed it a lot and it always seems happy.

Mines on bottom and started as 2 heads. Now I have 16! Med. Light and a little flow is all the need. Leave it in 1 spot for about 3 days at a time. If it looks like its starting to come out at all leave it there longer. Mine closed up for about a week when I first got it. To much light and it will really lock down tight.
