This is in the 75g there are quite a few of them. Looks like some sort of worm that attaches with its foot at the bottom. You can see it swinging around on the powerhead cord here.

I would think it is not a worm but a real small anemone of some sort (aptasia, tulip or majano) or a really small zoa but it is only visible for a brief time
Half to agree looks like a small anemone.
Your talking about the thing attached to the cord of the little white things moving around? Little white things are a pod.(ispod to be a little more specific) As far as what is attached to the cord it is hard to say. Does look like perhaps a zoa polyp of some sort or an anemone. Yellow polyp maybe? Possible to get a different angle or a higher res still image?
Lol yes I’m talking about the thing attached to the cord, I’ve figured out what pods look like by now lol. I took some more vids of it, so tiny it is hard to get a good pic of it plus it moves. I would think aptasia, but the ends of it (fingers) look ‘frilled’ like singed hair almost.
I honestly remembered the first time I saw that type of isopod. I hadn’t seen them in my system and was at the computer moments later searching the WWW to figure out what they are. I realize most people just see a tiny little critter moving around and call it a pod, but I like to know exactly what it is.
I just assume pods, there are TONs in that tank (75) tiny to large, many different looking types. I’m guessing since there isn’t anything in there to eat them.
+theres nowhere for them to hide,not much lr. idk about the mystery creature.

Big large refugium. Aka refuge from predation. In my opinion it is very healthy for the corals to have that much plankton in the water all the time. Perhaps that is another reason why your Duncan is doing so well.(besides coming from a good source 
)
Well this is in the 75 which only has some snails, anthelia and the mystery creatures
I’ve had anemones appear in a tank a year after adding animals. You think that’s all you have in there, but there is likely a ton of stuff you don’t know about that could appear seamingly out of no where. Post if you get better pics. I hate when I don’t know exactly what something is.
I will upload the other videos he took onto my photobucket account. It will take a little while
In that image it does appear more worm like but still think is an anemone (aptasia).
I wonder what they are living off of?
hydroid perhaps?

I don’t think its a hydroid, but I could be wrong. I did see a few of those in the that tank, maybe they are feeding off of them? Which are then feeding on the pods?
Are aptasia photosynthetic?
A few more pics and another video (all horrible, i know)

After seeing these last pictures I want to change my answer to hydroid (specifically Myrionema) . Get rid of it. on the wire scrub the wire outside of the tank. On the glass scrub it off and make sure it gets sucked out. On a rock either kalk it or get a screw driver or chisel to dig 1/2 inch deep to get to the root.
From a quick read do not touch with bare hands as they are a viral and bacterial infection waiting to happen.
Hmm looking that name up they look pretty similiar execpt for the fingers, these have a ‘singed hair’ look where as those are long and straight (like yllw polyps). According to what I read they are mainly dependent on light so I’ll kill the light for a few days and see what happens!
