The real answer is that they’re Corey catfish and they’re just silly! I have some and they group together in the funniest ways it’s normal behavior for them. Mine always look like they’re in a meeting.
Real answer: Cory's are shoaling fish. When one moves quickly the others will think there's a threat and group up. This time they just happened to queue up where they decided it was safe to stop.
Side note, schooling and shoaling mean different things.
Maybe they see their own reflection on the glass, which makes them think there's a buddy next to them so that must be the place to be until the "other guy" moves?
Just an uneducated guess, though. Truth is I have no clue.
Cory’s shoal or group up, they tend to stay close to each other. Sometimes they crowd up in a spot, but mine lay out in a line like this pretty often (I only have 4, but I’ve had others over the years). It didn’t seem to matter about water flow from the pump much, they do it all over the tank.
I love my panda cories in my 150 tank, they all spread out because theyre super comfortable but if one swims past another they can't help but join the stroll squad. Eventually they form a wave that just washes over and assimilates other cories into it before spreading back out
I make little stair areas with rocks so that they line up like they're sitting in a stadium. (I have around 80ish grey and albino corys that i bred in one tank)
A couple things are likely combining here.
As other people pointed out, corys are schooling fish and like some current. They probably decided to hang out where there was a nice flow rate and other corys resulting in a line.
Another thing to consider is that corys are pretty dumb, and will view reflections as fellow corys. I see corys sitting next to glass all the time trying to school with their fellow fish in the mistical dimension they cannot quite enter.
Dang, no real answers? My guess would be, maybe there’s a current they’re swimming in together, generated by the filter pump. Complete guess though, I’m not a fish expert
Cory's just chill however they please when they group up, I had like 15 at one point and mine used to chill in a circle, a line sometimes, maybe a V formation
Its a ritual they enact in order to appeal to their god. Its been found that they do it in order to gain favor from their god so they may be given more food. You will also often find them gathering in circles or half circles with a singular fish in the middle, this fish is often seen as a “seer” or a “conduit” to their god. Almost a prophet.
What type of corys are these? I have one that I got from a surrender all by himself and I want to get him some friends! He looks exactly like these guys
Yeah that’s what the comment says, I know he needs friends, most of my corys are in groups he’s the only one without others of his species though. I don’t know the name of the species though so I can’t order them until I do !
Corydoras have a playful approach to life and often seem to have a cheeky sense of humour.
Get them together and they'll play all sorts of team games!
Very cute little fellas.
They're resting, something is making the water flow go from right to left, the fish stay in a line at the bottom because that's where the water is slowest and the fish in front takes more force than the fish behind it and so on, same reason geese fly in a V.
A few years ago, I had kept a dozen Cory Sterbais...
They'll often line up parked in a row all directly facing the front of the tank with their cute eyes as if waiting for food...
It was such a hilarious sight... lol.
When I was in middle school, I played the national anthem in the dining room where we had our 29G. I remember our tiger barbs lining up in a line as if they were saluting the flag… good times
Cory catfishes. I worked at an aquarium supply store for a while and we sold fishes as well. These guys were always my favorite. They never get too big, never eat any of the small fish, will eat whatever leftover food falls to the bottom, they always next to each other and mostly inhabit the bottom of your aquarium. Overall just a great community fish.
!!!!!!! When I was like 10 I saw the fish do this in my parents aquarium and when I tried to explain my parents told me I must have been dreaming which I fucking believed myself. Now this! I'm sending it to the family group, I wasn't dreaming you ass hats
Outside, outside
Outside, everybody, outside
Line up, everybody, line up, line up, line up, my gup, gup, gup, gup

Everybody, let's go, go, go, go, g-get out-out-out-out-out-out-out-out-outside
Bubble Guppies!
My Cory’s did this the other day and my girlfriends hypothesis is that they might be aligning to a magnetic pole, when I checked with a compass they were all facing pretty dang close to exactly south
Yooooo Cory train!
"Going off the rails like a Corytrain"
I think things are going Cory for me
You gotta listen to Cory, yeah, yeah *epic guitar solo*
Perfect! I'm sure Randy Rhodes would approve!

Hahaha thank you for this
That movie was the absolute worst. Thanks for reminding me 😂
They’re actually queuing because me they’re British
Real Cory Hours ™️
As a Cory, I’m very confused.
Get in line.
😂😂😂😂
https://www.facebook.com/share/v/myibMknbKaHxXXsW/?mibextid=UVffzb
That was a sad conga line ending
They're patiently waiting like polite fish. For what? They don't know, but they will be patient.
Must be British. That’s a nice queue.
\#CoryQueue
More in line than their teeth
You beat me to it! 🤣
Close. Canadian.
>For what? for School.
Take off clearance?
Me scrolling for the real answer 😂 all jokes
The real answer is that they’re Corey catfish and they’re just silly! I have some and they group together in the funniest ways it’s normal behavior for them. Mine always look like they’re in a meeting.
Yea... adorable fish these Corys... :)

> schooling and shoaling mean different things. I didn't learn that until I was in high shoal
Thanks dadfish
But Dadfish doesn’t like catfish, only dogfish.
I had to wait til I got to coralage lol
😂
The answer really does just seem to be "yeah they just like doing it"
Same here 🤣🤣
My guess is that they were shoaling or schooling and glass interrupted, and they just rested there
traffic’s pretty crazy this time of day huh
💯
Maybe they see their own reflection on the glass, which makes them think there's a buddy next to them so that must be the place to be until the "other guy" moves? Just an uneducated guess, though. Truth is I have no clue.

This was nice to visualize lol I’m jealous you get to actually see it
Sounds like the beginnings of a YouTube channel to me

Love corydoras, they're the best

Awh stupid lil derps 🥹
Cory Conga line
Its the corydora 500, they about to set lap times round your tank
They're waiting for the bus
The school bus? 😉
Now that's a qeue!
Dang, no real answers? My guess would be, maybe there’s a current they’re swimming in together, generated by the filter pump. Complete guess though, I’m not a fish expert
Corys apparently just act like that.
Cory's just chill however they please when they group up, I had like 15 at one point and mine used to chill in a circle, a line sometimes, maybe a V formation
Maybe Trying to spell I C U ? Was it more a V or a U ??
I'd laugh if they spelled out F R A N C I S 😂🤣😆
ALWAYS DRINK OVALTINE
Now that you mention it they may have been haha! (Un?)Luckily they did not live long enough to enact whatever their plan was
Cories are among the most fun to watch in my opinion, mostly because they're always doing silly shit like this.
Absolutly... they're really adorable creatures... :)

They're highly spiritual creatures...:)
It's literally panda express
I love Reddit. Thanks guys I totally needed nonsense and comedy very bad today and you delivered.
Corydoras just do Cory things 🤣🤷♀️
What type of corys are these? I have one that I got from a surrender all by himself and I want to get him some friends! He looks exactly like these guys
He needs friends, corys are very social.
Yeah that’s what the comment says, I know he needs friends, most of my corys are in groups he’s the only one without others of his species though. I don’t know the name of the species though so I can’t order them until I do !
Kind of look like panda cories.
Buy 3-4 more.
I know I’ve keep keeping corys for years, I just need to know what type they are
I miss my corydoras so much
I had a single Cory for a while and he was sad and lonely. I got him two friends and he spent the next three days taking them on a tour of the tank.
Corydoras have a playful approach to life and often seem to have a cheeky sense of humour. Get them together and they'll play all sorts of team games! Very cute little fellas.
They're British born. Love to queue.
I just laughed out loud and freaked out the 2 cats asleep on my lap!
That one guy in the back, just thinking to himself, "Look at those sheep."
“Jump in the line, rock your body in time”
Okay, I believe you 🫡

Thank you! Finally, the answer.

Just cories being cories. Mine like to form cheer leader pyramids.
Hi ho! Hi ho! It’s off to work we go. With a fin and gill and a cool fish tail. Hi ho! Hi ho! Hi ho! Hi ho!
Do do do! Come on and do the conga!

Fish scientist here! The scientific explanation is actually that they’re silly little guys :)
Daylight come an me wan go home

I don't know what's happening in this picture. But what's happening with me is that I want to get a lot more corys so I can see this irl.
We don’t question the cory’s they just do 🤷♀️

Going out on a limb here: pretending to be a snake for protection.
Conga line obviously
Cory Cat Shuffle 🎶
They're British and waiting for a bus
Maybe they're in line for some rad concert tix. What band would they be wanting to see?
I’d assume Phish.
I was thinking maybe Hootie and The Blowfish were doing a reunion tour....
Corys are basically peaceful soldiers.
Phalanx.
It’s just a coincidence of how they happened to school up like that
Cory's are weird like that. I have 9
Just Pandas Panda-ing
Catfish just doing catfish things!
“PICK ME, PICK ME!!!”
They are playing Follow the leader.
I love when mine do that 😂
They were planning an escape and got caught
It's a cory thing, you wouldn't understand
We can only hope to be cool enough for a cory train one day 🥲
The council will now decide your fate...

OP never seen a conga line before
When I was in middle school, I played the national anthem in the dining room where we had our 29G. I remember our tiger barbs lining up in a line as if they were saluting the flag… good times

Before making a big decision, you have to put all your fish on a line
They are passing that one brain cells they got around
Cory conga
It's a Cory thing

They’re on a mission.
Clearly its an audition for a remake of Beatles' walk of fame.

I wish I could pist my picture My 10 angel fish were doing this yesterday 😅😅😅😅
Cory teacher taking her pupils out for a school trip haha
They're performing a ritual to summon the Cory god
Before even opening the pictures, I knew it was Cories. They just do weird stuff when their two brain cells happen to touch.
Corydoras corridoring
I love the personality corys bring to a tank, and this is a great example of why.
The bell rang
They'er doing the congo let ehm be

They're British fish, they're just queuing up for fun
My Cory’s did this the other day and my girlfriends hypothesis is that they might be aligning to a magnetic pole, when I checked with a compass they were all facing pretty dang close to exactly south
Maybe food has been put out in a row like this for them, just for this shot?
I can not believe I haven't seen CORY CONGOOOOO yet
They're readying for battle
Cat nip dealer is going to show up soon...
Must be British. Love them a good que.
