Look like a Rocket, ID please

[SHNICI]

I have this creatures some time ago in the DT and in the QT tank and in another isolated QT (which never had to be mixed water or something with the other 2 tanks.
It look completely as a rocket....., it move very fast and it retract it self when it's flowing around. one I found it start to use very small gap on one LR, and it act similar to duster feeder worm, but looking in the WEB for long time ago..., still can't find something similar to it. It's like 3x3mm big and it look like jelly fish here are macro photos, and video. Sorry but few times I lost the focus on the video, because I use macro lens, so:

Thank you @Crabs Mcjones
Ok, I read they will go by them self, but the tank in which they are isn't new..., just can't find out are they good or bad..

I dont believe they cause any harm.

Ok, I'll watch them, and if I notice they are coming more and more..., then I'll think to remove them somehow.

Look like jellyfish.

Yep, you are right, but can't figure out from where I can get jrllifish spores xD
They look interesting once they attach to peace of LR and they act as a fan worms, look cool there, but really can't find what they feed on, just in case if they can cause problem for the corals. And I find some info, they can release toxins in the water (like most of the corals in the tank actually)

Thank you @Crabs Mcjones and @KJ

Looks like an athecate hydroid to me (pretty much the same as said above). My first instinct was a Gonionemus but it doesn't have the cross-shaped gonads, so it was quickly ruled out

but it don't have any tentacles on it, I watch it and under microscope (can't take photo from now), and one of them which occupied hole on LR start to look now like duster feeder worm..., just because it start to build up a thin tube around it.
Still have few of this like on the photo, I'll try to take and post microscope photo of it.

if it is not one of your preferred tank inhabitants, I would remove it completely. These may live off detritus and other stuff, but also have the ability to attach to liverock and reproduce. They could even be an intermediate stage of something that is large and bad for reefs. Some intermediate stages of jellies, coral, etc, act like mini jellies .

Agree with you about intermediate stages xD...., I'll keep them, I figure out one where stuck..., and like I say it look like duster feeder..., have few nice looking in the tank.... (it's possible to be some of them...), but can be from different LR just bring it in.
I'll watch them, and will decide..., I hope they aren't bad hitchhikers..., looking on almost each think/creature which I see on the web, how it reproduce, and I'm trying to attach this one to any ....
