duncan coral

I've had this one head duncan in my reef for a year now. He has started growing 4 baby heads around the perimeter about 2 months ago. I have him near some xenia, which don't sting. I also have a rhodactis and a clove polyp near him. A frogspawn is not close but is in the tank as well. I have...

Fairy new to the hobby and recently purchased my first Duncan and I'm loving it! They are reactive, they have beautiful colors, appear to be peaceful and even are a good clownfish hoast. I'd love to hear people advice, experiences, and photos!

Duncan never fully extended since I got it at my lfs about 5 weeks ago.. today I noticed that the green skeleton is browning out and falling off. My other corals are great.. hammers are splitting, torches are extended but my Duncan isn't doing well.. would it possibly be to much light? Or not...

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...

So, I have this Duncan coral that I’ve had for about 5 days…. It’s been thriving and I’ve spot fed it and seen it eat. It’s been doing great but today I saw it contorting like a lot almost to the point where the one head seemed like it was going to split in two. Is this normal behavior I...

Take a look at the Duncan coral pictures to help me confirm that it’s dead. I am pretty sure it is but I want to be rational and not just kick him. Thanks. Also, are bleached corals able to be saved to a certain point? Had 3 that didn’t like the light one day and turned all white.

Just curious if anyone’s ever had Duncan’s that form two heads in one like this one or if it’s a common occurrence?

I set up a new saltwater tank two months ago. A Duncan coral was my first piece and has looked great. While I still really dig its look, after a month it has not really grown at the base, but it’s extension out of its base has increased a lot. But...it’s tentacles used to be thin and pointed...

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...

I've had my duncan coral in my tank and it's been doing fine for more than two months, but recently it was stung by one of my nems where there used to be a little hole in it with a polyp growing out of it, but now there's this weird thing growing on it that seems spiraly and is dark red. Anyone...

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...

So I just watched the tidal gardens video on Duncan coral and their Duncan’s polyps were al stretched out and flowy like a torch coral. Does anyone know why mine looks like little stubs? Or how to make it look more opened up?

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.

I have had a duncan coral in my tank since September now, and the past month or so especially it has been completely closed up. Can anyone help me figure out how to encourage it to open back up. It's one of the centerpieces in my tank so it would be awesome to have it back open again. Almost...

ok so i’ve been noticing that some of my lps corals have not been opening up fully such as my frogspawn my duncan and then my blastomusa. the only thing it could be is lighting but here’s some pictures of them and some perameters ph 8.2 dkh 8 nitrate 2 salinity is 1.024 and i dont have test kits...

Midnight Clownfish trying to host duncan.

I know that Clownfish in aquariums are known to host with random things, but has anyone confirmed seeing one try to host or even successfully host on a Duncan Coral? I am asking, because my Midnight has been hanging around my Duncan lately and rubbing up against it. This has only been over the...

Hello I was curious on how much this guy is worth. I won it for free on an auction. it has about 11-12 heads probably 5 are baby heads. Picture is from when I just added to the tank it’s still opening up.

I recently came across Duncans and were interested in adding in the tank. I’ve read mixed reviews online with some people mentioning no issues and others cautioning against. From all I’ve read they are peaceful so was curious to understand if anyone kept or any info if they are compatible with...

A littleback story.. a few days ago my peppermint shrimp was seen trying to take food from my duncans. On my IG @spellboundreefing a handful of people warned about them eating their coral and that I should take him out. Today I went looking for my peppermint ship my duncans ATE HIM! They look...

Hey all, I’ve had a tank for sometime now and just put in this new duncan coral, and I’m wondering what the exact species/family of duncan I have. My friend has one and it’s whiskers are very long but mine are very short. I’ve read stuff about flow and all that, but I’ve changed it around and...

Hi all! So I am still new to the hobby and recently inherited a new (to me) established reef tank. For the first few days my Duncan coral looked beautiful and was fully open. But starting yesterday afternoon it’s only opening about half way and the stem has brown on the lower part. I’m not...
