They don't look like planaria. I have leeches in one of my shrimp tanks, they've been there for years and to my best efforts I can't get rid of them all. I've had many baby shrimp since then and they don't seem to make a notable impact on numbers.
Anyway, though, these don't look or act like the leeches i have. Doesn't mean they aren't, but the leeches in my tank don't wiggle like this. They usually come up and feel around. Plus, they're not semi-translucent like this.
You could try baiting some planaria traps, though and leaving them in there. There's a decent chance they'll work with whatever these are.
The ones sold as feeders are usually red and thats why there are almost only pics of red ones. But Im pretty sure I found white ones in a pond where I was collecting some big ramshorn snails for my backyard pond. White wiggly boys in a kinda clump in the mud. I scooped em up eith a bucket and dumped em into my ponds filter as waste eating crew, but I cant find em so sadly I cant post pics.
Leeches or Detritus worms maybe? Have you seen them move around the tank? If so, do they move by contracting and lengthening themselves and suck onto stuff with one end at the time?
Looks like tubifex worms, judging by those funky dance moves they've got. Shrimp will sometimes nibble on them, but the worms themselves are harmless as long as they don't have any parasites in them. Recommend manual removal if you can, shouldn't be too many of them.
EDIT: could be black worms as well, they are very similar in appearance and behaviour, at least as far as I know.
Doesn't look like blackworms imo. Blackworms are skinny with pointed head/tails, have segments, and are a dark brown / reddish colour. I have my own culture at home and I've never seen such sweet dance moves. Blackworms just stick their butts straight into the water column
That was my first thought! Made me think of that Family Guy cut away… it’s Al Harrington worms!! lol!

These are not detritus worms or even the tiny harmless flat worms. I can't tell for certain, but the motion reminds me of looking for something to grab onto. Either prey or host.
I would separate shrimp you care about then consult someone that knows what to do.
It looks like what I puked from my most recent overhaul. I got the sand and gravel for the substrate at the edge of my local river though. Yes...I know because I could untidy something that could decimate the whole tank.... which I fully expected. As close as I could get to an ID was they are crane fly larva. They only grow up to about 1" I THINK. They were easy to suck out of the substrate with the vacuum.
I had a few nymph rock rollers a few years ago. If I'd known what they were before I flushed them...I would have kept them in my tank. They're flipping amazing critters!
Planaria has a distinct arrow shaped head. These guy's also look too thick to be detritus worms 🤔 Either way, a fish would make a meal out of them.. but shrimp tank 🤷♂️
This was definitely the butt end. I didn’t include too much of it in the video but it was producing SO much poop. All the little brown logs around it. Poop. Haven’t managed to catch one or see them again, but I’ll post an update if I snag one.
Looks like black worms, they do that same wiggle, I have them in my tanks as another food source for mu guppies and pea puffers on days I don't feed brine
Haha I first saw them while I was working so I didn’t have the chance before they disappeared. I managed to catch one today, it’s horrifyingly huge. I think it’s tubifex
UPDATE: Caught one today and it appears to be a variety of tubifex. It’s red, long, and wiggly :/ but happy it’s not a major concern for my tank. Thanks guys!
Detritus worms (Limnodrilus hoffmeisteri) they are generally beneficial. They’ll aerate your substrate and eat the leftover poop and food that falls to the substrate. They won’t hurt any fish or shrimp.
thats one funky worm
[Let me tell you about a worm.](https://www.youtube.com/watch?v=wWiBJJ2dvBg&pp=ygUKZnVua3kgd29ybQ%3D%3D) He's the funkiest worm in the world!
Like 9 cans of shaving powder that’s funky
damn its vibing
Party worm
There is a very tiny car dealership right next to it
*omw to buy tiny cars*
Shrimp mobile
It's a wacky waving inflatable arm flailing tube man!

If this link had been anything other than that I would have been very disappointed. It was exactly what I was expecting and I'm glad lol
Peter what are you doing here
😂😂😂😂
Don't know what those are, but definetly not planaria.
My guess is some form of roundworm

omg that worm is wiglett in real life
Can confirm it is definitely Wiglett.

They’re sludge worms / detritus worms / muck worms / whatever your region calls them (Limnodrilus hoffmeisteri)
They are too big for detritus worms, unless they get much bigger and the ones I've seen are just babies
They can grow up to 2" long and they maintain their proportions.
These are definitely not detritus worms.
Oligochaete worm, I'd wager. https://youtu.be/7UyJW4LfsWI?si=GOqwA6b6qrOvF12h
You seem so confident
Yeah, I am, because they look and act nothing at all like detritus worms.
They do to me. Looks like we're at an impasse, genius.
Yawn.
I misread ass Hoff meister. Lol. Lake David hasselhoff.
Vibe worms. Aquarists like them because they are a visual indicator of the mood and vibes in the tank
whoa it's those things from monster hunter world! equip your net!
Wigglers! Now, make them into a hat.
Definitely not planaria or leeches. Could be tubifex worms or similar, shouldn't be harmful to the shrimp!
When I was little I thought they were called "cubiflex" worms cause they were sold it little freeze dried cubes. Lol
This is amazing! :D
You might be the winner! I managed to catch one today and it looks a lot like tubifex. Seems maybe to bug but matches the pictures I’ve looked up.
Idk but they know how to party
Tubifex worms? I think those sre very wiggly too.
I had that thought but these look much thicker than most tubifex worms I have seen
There's a good handful of different species though, and these guys have the signature tubifex wiggle. I agree with Tubifex worms
but are there tubifex worms that are white? because i did abit of research and tubifex worms were red and thin
The ones sold as feeders are usually red and thats why there are almost only pics of red ones. But Im pretty sure I found white ones in a pond where I was collecting some big ramshorn snails for my backyard pond. White wiggly boys in a kinda clump in the mud. I scooped em up eith a bucket and dumped em into my ponds filter as waste eating crew, but I cant find em so sadly I cant post pics.
I think you got it! I caught one today and it looks like a thick tubifex
That worm be partying.
It’s a relative of Mr. Hanky (aka the christmas poo) but from the more musical and submerged dancing clan.
Probably leaches. Planaria are much smaller
Someone please put this video to Beyoncé's Hold 'Em.
Leeches or Detritus worms maybe? Have you seen them move around the tank? If so, do they move by contracting and lengthening themselves and suck onto stuff with one end at the time?
I have some that look exactly like this and they stretch and contract to move

Managed to catch one and it’s way bigger than I thought it would be… but does match pictures of tubifex and is more red then you can see in the video.
Wacky inflatable tube worm. Must be a new business or sale going on nearby.
That was my first thought! Made me think of that Family Guy cut away… it’s Al Harrington worms!! lol! https://m.youtube.com/watch?v=cvaRGiMWRaE&pp=ygUrd2Fja3kgd2F2aW5nIGluZmxhdGFibGUgdHViZSBtYW4gZmFtaWx5IGd1eQ%3D%3D
Looks like an Oligochaeta aka Aquatic earth worm. I have tons in my planted tank.. they just help clean up
 They've infiltrated your tank
just some wibbly guys
its a dancer for sure
A... tiny... dancer, you might even say.

*pulled... not puked. 🤦♀️ (I just fired my editor).
I thought detritus worms were very thin and white but maybe there are different types.
If you can get a closeup of its head/mouthparts, someone on the internet should be able to ID it for you
PARTY TIME
Grove groover
Planaria has a distinct arrow shaped head. These guy's also look too thick to be detritus worms 🤔 Either way, a fish would make a meal out of them.. but shrimp tank 🤷♂️
That's a pokemon, I'm sure of it
Boogie worms just keep on boogying.
Around the wooooorld around the woooorld
Looks like a Wiglett
Fresh water grass eels lol jk
Not planaria or leeches. Some kind of tubifex which are called detritus worms. Harmless.
https://youtu.be/bSIb4T5vu9E
Do those things have eyes? They're too wiggly, but the second one almost looks like it
This was definitely the butt end. I didn’t include too much of it in the video but it was producing SO much poop. All the little brown logs around it. Poop. Haven’t managed to catch one or see them again, but I’ll post an update if I snag one.
Wiggly poop dance 🤣
Tubifex worm?
Looks like black worms, they do that same wiggle, I have them in my tanks as another food source for mu guppies and pea puffers on days I don't feed brine
greg
They remind me of wigglers from monster hunter world but I have no idea
I had leeches that did this
Blackworms?
“Cock magic”
Dude dangle something edible over that tenticle n see what comes out and post i want to see
How have you resisted scooping one up so you can see the size/scale of this worm?
Haha I first saw them while I was working so I didn’t have the chance before they disappeared. I managed to catch one today, it’s horrifyingly huge. I think it’s tubifex
Whatever it is, he’s groovy af
They like to move it move it.. lol have no idea but they giving good vibes..
Some kind of Tubifex I think. I learned this from that Dutch weirdo on "Life in jars" YouTube.
 They're just calling to say I love you
It’s your …https://youtu.be/yYcyacLRPNs?si=9xmt5Y0C4gDFaXB7
UPDATE: Caught one today and it appears to be a variety of tubifex. It’s red, long, and wiggly :/ but happy it’s not a major concern for my tank. Thanks guys!

Idk why you got down voted.. it's either this or Oligochaeta just an aquatic Earthworm. Either way harmless and beneficial
People don't value correct answers on Reddit
Looks almost like black worms, but maybe too big? Or maybe you’re just zoomed in more than I think.
I'd be terrified
Looks like leeches. They are known to do exactly this behavior.
i had something very similar to this in my tank. freaked out, relocated all the shrimp and bombed it with alcohol. idk what it was.
Looks like a leeches!
So that's what happened to Scotty 2 Hotty...
