duncan

Hard to see, about the same color as the body, not sure if it was there before or not. It is kinda limpet shaped? But honestly, I don’t know and I would love some input.

Hello! I have a 20 gallon running with live rock, aragonite sand, an AI Prime, and Reefflowers Coral Salt Mix. Right now I have lots of zoas and GSP that are doing great. The only stony coral I have that has consistently done well in my tank is the duncan colony. It is growing super well and I...

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!

My Duncans has retracted all of its tentacles, and just looks flat now... Its been like this for 1.5 months now... but yet its still growing new smaller heads.. Alkalinity = 9.8 Calcium = 480 Magnesium = 1500 Nitrate = 11 Phosphates = under 0.25 Ph = 8.1

I couldn’t figure out why my Duncan is receding so I put my camera on it for 9 minutes with flow on and off throughout. Tiny pods like creatures are running around at the base and I think those are what is irritating it. Does anyone know what these are?

I have two large Duncan colonies available that I have grown from single head frags. Both are balling types. Located in Las Vegas with shipping available. Each Colony has easily over 100+ heads but more like 150+ heads. Top colony (shorter polyps) $350 hipped Bottom Colony (Longer polyps) $400...

So my duncan isnt looking too hot. Bought 2 from same store and were placed next to each other add at the same time also. One is doing great the other wasnt. I just recently moved him down to the bottom of the tank after giving him over 2 weeks of not coming out. ive had good parameters as the...

Picture Attached! I just got a Duncan a week ago, first few days he was doing great. But yesterday it completely closed up, today it’s tentacles are completely retracted and it’s mouth is open. Is it dieing please help. Water parameters are all in check, only 10 point down on calcium so I...

Any idea what these tube things are on the base of my Duncan?

Hey, I just started my first reef tank and just got my first duncan coral. After looking at some images online of these corals, I noticed that my coral looks nothing like them, not even small frags. It looks like a SPS to my beginner eye, it has many small polyps. Can you guys tell me if this...

So for the past 5 days my Duncan's have just been angry. Color looks good, flesh is fine and not receding, but it will not inflate/extend fully. I DID have to move it about a week ago, but it was open for a few days after just fine. Literally only moved it about 2 inches. Just got it to a...

Recently purchased a Duncan Coral for my 10 gallon tank and today I came home to find an odd scenario. The duncan has its mouth open with a red tentacle coming from its mouth. All of the corals around it are agitated. I have owned duncans for a while now but have never seen this. Doss anybody...

Hey guys, newbie here, Sexy shrimp has been hanging out on my Duncan for a couple of days and I noticed the coloration on the stem has been decreasing not sure why or maybe I’m overthinking it? Hopefully pictures aren’t too bad lmk if I need to remove him he loves to hang out on the frag rack. I...

I bought a Zoa rock today and it has this on the end. I don’t know if it is a Duncan or an anemone it’s more purple in normal light. I bought a pair of clownfish the other week but don’t have an anemone yet so would be great if it is one!

Hi all, Dendros, Acans, Favia, Duncan, Frogspawn, Hammer, etc... When target feeding, do you have to feed each individual coral mouth/head for every parts to grow? Or will feeding one "distribute" the food to the entire colony? Thanks!

So the story goes like this, I have been on a vacation for 10 days . My tank is 4 month old and the parameters have been stable .my brother took care of baby sitting while I'm away and tank is doing fine all this long except for ugly phase with different algae ( dino,red cyano). While I come...

So I’ve had my Duncan for quite some time now and can say that it is by far my favourite coral I own. It’s grown 4 new heads since the time I originally purchased the single polyp frag and looks absolutely fantastic! With this I can’t help but wonder why the base/skeleton hasn’t grown at all...

Hi all, I have this Duncan for almost 6 months and was happy as can be. It even grew in size. I haven’t noticed any changes until today evening. I have 2 head missing all of the sudden without warning. I mean yesterday had all the 5 heads and today I have one completely missing an one seems...

Hi reefers, I have a 75g tank, its running for almost a year now, recently (10 days back) i added a duncan frag, for the first day it was fine, fully opened, the day after it closed and never opened again, some reefers suggested to move it to moderate flow area in the tank, so i did. yesterday...

I have a single head of Duncan coral in my tank. Also have a large head of a torch, GSP, and 2 different mushroom. The duncan has been in the tank for nearly a month and has done well up until the last few days. Ive had to move him around a bit but he's been in his current spot for about a week...

Help! I was out of town for the holidays (~10 days, never again!) and came back to an angry tank. I lost a peppermint shrimp, cleaner shrimp, yellow tang and lawnmower blenny (my first & all time favorite :( ). I brought a water sample to the local aquatic shop and they said everything was fine...

Hey there Reefers! I want to sell my Duncan colony! It’s about 25-30 heads and growing. I’m asking $200 for it and will entertain trades. Located in Miami I prefer local pick up.

Hey folks! So I had a minor cyano outbreak. After chatting with some folks at my LFS, I took their advice (against my better judgement) and dosed with chemiclean. I was pretty hesitant about the use of chemicals as I am generally weary of any chemical additives. Hindsight being 20/20, I...

I have a small two headed Duncan coral in my NUVO Fusion 40 that I fear has Brown Jelly Disease (see photo). For the last two weeks, I’ve noticed it just wasn’t opening fully and I wasn’t sure why. Yesterday I found two or three hermits “cleaning” the skeleton. Today, I found both heads nearly...
