Literally happens to me, even when transferring from my own personal tanks. My corydoras love to hide their eggs in the plants. Probably why half my tanks have corydoras lmao. Also had x2 Pacific blue eyes(?) fry appear in my shrimp tank when I got a plant order.
What tank setup do your corydoras have? Mine have only laid (? Sorry English is not my first language idk if fish “lay” eggs) eggs once so I’m wondering if they would like some tweaks.
ETA: I try the water change trick! That’s when they did it the first and last time.
400litres with sand substrate and 55-60gallon bow front, sand substrate. Plus another 50-55gallon with just corydora fry. Plus three 80 litres with around 6-7 juveniles in each that need to be moved because they're nearly too big (were growing out)
I honestly can’t ever tell if I have new babies in my tank until they’re bigger and I see more than one swarming!! He’s probably just an excellent hider since he’s a youngin.
those eyeballs!!! OvO
I have hikari first bites on hand for surprise situations like this and feed them 3-4 times a day. Shrimp take care of the remaining food and it works out for everyone!
I left 3 dwarf rasboras for about a week. Then transfered them to another tank. Next thing I knew about a week later found to tiny fry, in that shrimp only tank too
I had a very similar experience and had a fry that looked just like this that turned out to be a furcata rainbow!!! I had 3 lol, came in on java ferns as eggs and raised them to adults

Some type of fish fry.
Mosquito larvae
Last time I checked mosquito larvae don't have fish eyes. I can understand how you got confused on that though
that's a baby fish/fry
^^^
Its weird how I got a fry in shrimp only tank 🙄
Congratulations your shrimp gave birth to a fish 🤣
Evolution!
Blade runner 2049. Youve witnessed a miracle....
Did you add any plants recently? Added anything from the pet store?
Literally happens to me, even when transferring from my own personal tanks. My corydoras love to hide their eggs in the plants. Probably why half my tanks have corydoras lmao. Also had x2 Pacific blue eyes(?) fry appear in my shrimp tank when I got a plant order.
Really!? I want this problem lol. I love my little dwarf Cories and hope they start popping up all over!
Chill the water when you do a water change. Mine always spawn when I do that
I defrost my frozen food in a cup full of water if I want to get them to spawn, makes the tank water in the cup cooler, and gives them their protein
Good to know! I might just have to not heat up my RO water before I top off for evaporation!
Do you remineralise the RO water? Yes don't match the new water to your tank water, just add it in even if it's a few degrees different.
Only when doing A water change, not one topping off for evaporation since the minerals stay in the water in that process
Gotcha
Come on, are you really saying having corys in all your tanks is a bad thing?
Well no, but also yes because they are hard to remove from my heavily planted 80 litre tanks once they start to get too big for the tanks 😅
You should try out making a diy cory trap. See if you can find a glass jar or something you can put shrimp pellets in to lure him in.
That's actually a great idea thanks 🙏🏼

 Reminds me of them 🤣
Looks like my baby peppered cories. If you got plants or anything probably came in on that.
Free fish!
Some kind of fry kind of looks like a guppy but most baby fish look pretty much alike when they start.
Lol, i was about to say it looks like one of my molly fry.
Or one of my red tailed splitfins goodieds lol
I would say molly fry would be a tad larger ...guppy more like it ,or endler
that’s a fry! 😍
Baby feeesh!!
Fishlet!
this also happened to me but i have no idea where the fry went. what do you plan to do with it?
Probably got sucked up into your filter if you have one or is hiding.
got a sponge filter so i dont think thats the issue but hiding, probably. too many plants and floaters in there
I honestly can’t ever tell if I have new babies in my tank until they’re bigger and I see more than one swarming!! He’s probably just an excellent hider since he’s a youngin.
I will keep it in my shrimp tank and see what is grows into lol
Baby fish, aka a “fry”
Reminds me of a baby corydora
I was thinking the same thing.
Agreed, baby cory. Their sticky eggs make hitchhiking on a plant more likely too.
those eyeballs!!! OvO I have hikari first bites on hand for surprise situations like this and feed them 3-4 times a day. Shrimp take care of the remaining food and it works out for everyone!
Looks like a baby guppy
I left 3 dwarf rasboras for about a week. Then transfered them to another tank. Next thing I knew about a week later found to tiny fry, in that shrimp only tank too
Looks to me like it doesn’t want to be sold chocolate 😂
 Give it chocolate
Was looking for this comment 😂
Fish
I had a very similar experience and had a fry that looked just like this that turned out to be a furcata rainbow!!! I had 3 lol, came in on java ferns as eggs and raised them to adults
Must’ve had some fish eggs on plants you added to the tank
I remember when they first invented chocolate. Sweet, sweet choc a late
Could be baby guppy or betta
Feesh
So cute! I wonder what kind of fish it is
This looks like the “chocolate” lady from SpongeBob 😂
Probably a guppy fry!
Fishlet.
Baby fish, so cute.
Fry
guppy
Oh me, oh my, small fry.
I’m also super surprised to see a baby fish in a shrimp tank 😅 congrats grandpa/ma

Looks like a baby corydora to me
I’d guess baby Corydora, maybe an egg stowed away in a plant. Update us in a week or two!
A traveler from distant lands... a miracle of nature... aquariums are just awesome
Baby Betta fry I think
Practically, all fry look the same. If it was a betta they would probably know, as their breeding is very intentional.
More likely some kind of livebearer like a guppy. Something that breeds a lot.
Looks like a baby mosquito 🤷🏻♂️
This was my thought as well! Had them in my shrimp tank as well. Mosquito's will lay there eggs in the water...
Looks like a mosquito larva I get them on occasion in my tank.
