Daphnia culturing and raising your own live food is one of the best things you can do for your fish, and Daphnia (also called water fleas) are some of the most nutritious and easy live food to DIY.
Cory uses a 360 gallon tub outside, a 100 gallon tub, and a 55 gallon tank. The largest tub is the best producing by far, and can feed Cory’s entire fish store once a week. The Daphnia are fed yeast mixed up with an immersion blender.
Snails, algae and duckweed will likely find their way into your daphnia pond. Daphnia tanks outside will end up with mosquito larvae and/or cyclops, which can either be good or bad.
Some tips for how to culture daphnia:
You do not need green water as a hard and fast rule, while it helps, you will have to feed your daphnia anyways.
Just like any other aquarium, be sure to maintain good water quality
Daphnia Magna and Daphnia Pulex are raised the same way
Daphnia take 7 days to reach sexual maturity, and have about 10 babies. You can go from 10 to 10,000 daphnia in a single month! Because of this explosive population, they tend to boom and bust (crash.) That’s why many people keep multiple cultures going at once
Having a large volume of water and a lot of surface area will really help. Some people don’t recommend aeration, but it has been beneficial to Cory’s Daphnia yields. A never-clog air stone seems to produce bubbles of just the right size.
Daphnia molt a lot, so keeping lots of calcium in the water will make a difference. Wonder Shells and crushed coral are both easy and inexpensive additives.
Starting with aged water, and only using it for water changes and top-offs will be extremely helpful.
To harvest your live fish food culture all you do is take a brine shrimp net and slowly move it through the pond (big/fast motions will stir up gunk from the bottom.)

Aquarium Co-Op would you ship out some Daphnia?
Wanted to know the same thing
Cory, is shipping to Canada something we can look forward to this year?
I'd really like to buy some of your sponge filters.
Do you have any plans to introduce your own line of matten filters?
Would definitely be cool to see an updated version of this
Thanks for this - the biggest draw to the hobby for me after 20 years has become the invertebrates and plants. As avid aquarists I think it's our responsibility to replicate the food chain so that we don't have to rely on manufactured food for our animals. And they are every bit as interesting as the fish!
that sound quality!! so cool to see how far you've come. you deserve it! hope much bigger things headed you way. keep up the amazing work
Coming up on 3 years ago. Only had my cell phone for a camera back then.
@@AquariumCoop 6 years now and it's insane
Love from 2022.
It seems like every time I get interested in doing something, up pops you with a video about what I want. Just Loving it! I have learned so much from you. THANK YOU!!!!
What a rough video 😄 you've come such a long way! Thank you for teaching us how to properly care for our aquatic friends. Thanks to you I've learned so much and can successfully care for my pets. ❤️ Keep up the good work! 😊
I think that might have something to do with Jimmy.😀
Man that is a lot of Daphnia.
Yeah, makes for healthy fish at the shop!
I bet it does.
Another good one...! Keep up your awesomeness...! My nature got blown away by hurricane Ian, so go enjoy nature for me...!
7:40 red cherry shrimp? Nice. Thanks for the great video.
Thanks for the insights. This is the best daphnia culturing film for me.
Wow, The channel has improved A WHOLE lot since this!
I love your knowledge and the tests you make on your own, you don't take for granted what everybody says. Thank you for
sharing I'll do it exactly as you're showing us. I'm already subscribed.
Yeah, I learn a lot when I experiment. Even if the outcome is the same as what everyone says. Should be some more daphnia info coming out later this year as I'm playing with some outside right now.
I would love an updated version of this video.
This helps alot to this day
Thanks You so much
First of all, congrats on a great video. Cyplops eat either the juvinile daphnia or the molted cases with the eggs inside them. Compete and eat is their motto. That's why you have less! I lived in Ireland and I could find Daphnia in a local pond. Here in Canada, it took a while to find some. I have a few goldfish in green water and I made a little round tank beside it, and a few inches higher and airlifted fish water into it in a failed attempt to settle out solids. BUT it was a total success at clearing the green water, the overflow or return (at maybe 1 or 2 liters of water per minute) sends excess daphnia back to my fish. The neat thing is that the daphnia is both the filter and the fish food. The splashing of the airlifted water means that the mosquito larvae cannot detect the outflow and they get sucked down to be eaten by fish too. Maybe this can work in one of your systems too. Neat that you have all these together. I have some little shrimp too but they did not last in the system linked to the fish, maybe they got curious and went through the outlet. I still have some in another pond in the greenhouse. Thanks again for your video. Very helpful. Brian
+Brian White Thanks for commenting. Yeah I've tried a few more systems. Still haven't perfected it. Thanks for the tips on the cyclops.
+Aquarium Co-Op You are welcome. Keep trying, nobody will have a perfect system, but I am sure you will get closer than most. A guy in a university told me the cyclops tip. I asked online, how come it is so hard to find daphnia here? and he told me that was the reason. I grew up in a fairly high lime area, and it was almost always easy to find daphnia and cyclops but I think that cyclops being starved of lime here means that they will eat even more of the daphnia resting eggs over the winter just to satisfy their craving for lime to build their own cases.
+Brian White can u tell me how to start the water for culture? any vitamin or mineral I need? or the pH for water. my culture always crashing.
+Okta Vindya I do not know why they crash. It is totally not my field of expertise, so this is a pure guess. Add eggshells or the ground limestone that they sell to put in garden soil so that they always have enough calcium and magnesium to make their shells. In the part of Ireland where I lived, soil had a high lime content. Here on Vancouver island, it does not seem so high. I have only had mine for 6 or 7 months. I keep them in 4 different places. I hope if one lot crash, I can replenish from some of the others.
Brian White thank you. Here in Indonesia they are all found in some crazy polluted water but when they brought to my home for starter, only little survived. So I thought its the water problem. I did get some tips on putting a calcium source as they need it for the shells. Thank you sir.
Hey I've been watching your videos for 3 year and it looks like you have come a long way keep up with a the videos
Thanks, Cory!! Another great informational video!!
Woah i wish i could have that amount of daphnia in the PHilippines bcs i cant find that in our backyard 😢
Wow cool thanks I think this is the most informative video I've seen on daphnia! Now I want some ;~;
sava stayton No problem. Just trying to help. I was in your shoes a couple years ago wishing there was more info.
That is awesome Cory!
Any tip on how to get rid of bacteria and parasites that might come with wild caught daphnia?
I took some samples from nearby ponds. They also contain copepods and ostracods (seed shrimp) and I'd like to start a culture that doesn't kill the fish.
Thank you!
Great video! Since it's getting cold now can I do this outside when the temperature is 30 or below?
Great Review. Thanks.
this is the perfect video with good tips and accurate information !!! very good !
I hope to pick this project back up again this year coming up.
If you struggle with having enough green water you can make a ton of it in seconds using powdered spurulina.
Thank you, I need to start these...
It would be nice to know where your getting those tubs. Costs of your setup would also be helpful. Thanks again Cory!
Nice One Bro 😍 thanks for the INFO 🎏✌
Daphnia can withstand the greatest temp swings out of any type of feeder bug
It’s the light that they are drawn to! I have a 125 that’s outside for my daphnia tank in Colorado. I have 3 open airlines for bubbles but not nearly that much air. Also, all I feed mine is spiralina. My reproduction isn’t nearly as abundant. What I get from you is more air and add yeast to their menu and it should help increase my daphnia production? Thanks
Water circulation keeps the daphnia food suspended instead of sinking to bottom and raise ammonia that leads to crashing.
Great videos!
Wow Cory! Your Quality has improved a ton! Anyway, do you ever sell daphnia at your store to start a colony?
Not yet, but it is in my new years resolution to start working on cultivating it again
very awesome
Thank you!
I thought I was going to see you feed the fish that handful of daphnia! So disappointed! Also, why did you leave that net of daphnia out for so long, aren't they going to dry up?
Cory!!! Make a new Daphnia video!!
Very nice video, you really inspired me to start culturing daphnia myself to feed my koi!
Could you tell me what the optimum temperatures are to culure them?
Nice vid
What food do you use for indoors? Could spend the amount of spirulina. Or the amount of all the food.
Make another daphnia pulex culture video!
Wow that's awesome, very cool Cory. Update for 2019 coming? Tips, things you would do better etc?
Can you keep the culture in the little bottle you get sent, in the fridge, if you don't need it all at once ? Thank you answers. ;-}
Wow, thats a lot of daph.
is direct sunlight necessary for the culture?
Thanks for yhe informative video. i'll start with a 6gal tank.
Sir how food for dapnia magna
Hi Cory! So I have been through 3 different cultures of daphnia that I purchased from eBay. I have a 20 gallon long tank with a sponge filter and a heater that keeps the tank at about 82 degrees. I use cycled water out of my Silver Dollar tank. I feed spirulina powder and activated yeast. Anything else you can think of that would keep them alive? My last culture didn't last more than 5 or 6 days.
Bigger water volume, most people can't handle the waste output from feeding and the daphnia molting. Also you have to have aged water as dechlorinator kills daphnia etc.
Thank you so much for the response! So the water that has been in my other tank for a week still has enough prime in it to kill the daphnia?
Nice! Our fire fish and wrasse love these! Are these freshwater?
old video i know but one of the better ones... just wondering, if you have a container outside how do daphnia get into that container to start with? can find them almost anywhere in the "wild" so to speak, but if you have an open container thats not linked to a water source, how would they get there as the life cycle unlike mosquitos doesnt have a flight path.
Usually you would have introduce them as it is unlikely for them to find their way naturally.
Imagine unleashing an army of neon tetra on those suckers.
Do they have drawbacks can i breed them in my tank i want them to breed in my tank and establish their population so the other fish can feed on them without wiping them out
Thank you very much
ben birkett Hope it helps you. Fish absolutely go nuts for daphnia :)
Thank you just want to give the fishs a treat also it is part of my biology degree
Very interesting, i have a 1000 litre tank daphnia are the daphnia need air aeration or not ? Or he can live without air stone aeration ?
hi could you supply a link or something for me to see where i can buy it and can it be shipped in a shippment for more then a few days?
thanks.
I'm guessing most stay near the top because that's where most of the phytoplankton/algae is growing.
How quickly do they reproduce? I have to do a science project (for biology at school) at some point. I want to do mine on daphnia, seeing how they reproduce in different environments.
Clarinet Catato he said in the video they start reproducing after a week
They pretty much double in amount per week.
@@animetronic6689 about 4 years late (never did do that daphnia project lol), but I may consider keeping daphnia for my fish now (I’ve gone headfirst into fishkeeping haha)
@@pae913 yeah I know that. Have fun with your fish. About to go into breeding lots of thing. Rams, corys, apistos, discus, angels, plecos, rainbows, and lots of other things. Should take a good 5 years!
@@animetronic6689 ooh nice! Good luck!
I hope that you make a new video on this topic. :)
No offense but you're videos today have a much better quality than this one. Haha.
I've watched a few Daphnia culture vids but this one has got to be the biggest container I have seen used.
Anyways, thanks for the videos!
+Jayson Javier yeah I havent played with daphnia much lately. Its still on my to do list.
Thanks for the reply! Well, no rush. Keep doing what you love, that's what's important. :)
any filtration on the daphnia pond or just air and duckweed ?
What if you accidentally have them? I have no idea where they came from
they most likely aren't daphnia. Look at seed shrimp pictures
sir can provide me complete instructions on how to start my own daphnia culture
Hey thanks man. Good job in making this vid.
Say...may i know how much do you blend the spirulina n yeast for the indoor setup each time and on what interval?
Cheers.
I think I overfed my daphnia last night. Made the water really cloudy. They are still alive today. What should I do?
id like to watch a single small fish in that tub
May be a weird question but i scrolled through and couldn't find an answer for it...if I were to set up a 10 gal indoors would there be any foul smells????
Yes, I kept it in my balcony.
And the culture smells terrible if I go near it.
Plus you feed it yeast, which adds in some more odour in it.
Has anyone ever had luck getting wild daphnia. Im in ontario and I cant seem to find any local resources.
Cameraz Eye I'm currently culturing a small species of daphnia/moina that I collected from a water-filled tire rut in my neighborhood. I'd recommend looking in stagnant bodies of water, preferably without fish (vernal pools, etc). I'm in the USA, so I don't really know what's available for purchase in Canada, but maybe try aquabid.com or a local aquarium club?
Hello,
Has anyone tried fishmeal as daphnia food? I have seen a number of videos including this one. One inconsistency I always find is about how fast they reproduce. Just two days ago I have set up a tank with capacity of 160 liters. I put a cup of ground fishmeal and a little starter culture of red daphnia. Within 48 hours it is like a billion baby dahphia in my tank already, very dense. Is it not way too many daphnias than what is usually told in these videos?
হায়দার আকন You can have roughly 19,000 per gallon in a moderately large tank I think.
Cory, I'm considering culturing green water to feed to my daphnia that I plan to feed to my fish in my planted tank. Is it possible to create a green water issue in my planted tank through cross contamination?
Plants absorb the nitrates from the water and tend to shade out the alga in green water so not too likely to be a problem unless you over feed your fish, then you could get major algae outbreaks. If you do weekly or twice weekly water changes of 25% or more you should be okay but take it easy on the feeding. That's the easiest way to prevent problems.
Hey Cory I have one issue with culture ,I'm using plastic tub for my dalphnia culture and I'm feeding dry yeast 😅the problem is fungus ...like fluffy white thing on all sides of the aquarium 🤔what is that it's harmful or how to remove that
i was raising scuds without knowing what they were
Can different species of daphnia be kept together in the same culture?
I have a very strong culture of Daphnia magna going and I'm starting another of ceriodaphnia, keeping them together would simplify things for me.
I haven’t tried that myself, so I am unsure.
@@AquariumCoop I will try it once I have the ceriodaphnia population built up suck that I can afford to use some for the experiment.
Do you run Daphnia Magna with Daphnia Pulex in the same enclosure? Do you harvest for sale?
Can daphnia be harmful to people? Like if they are taken in from water being swallowed in a pond?
🙏😎🏆
Hi Corey, I have a setup I'm building where I'll have a guppy tank sharing circulation with a small open bin pond (pond is like 5-10 gallons and a 20 gallon glass tank), and a home made filter. I was thinking the little pond could maybe house a daphnia colony, there would be a bit (not a lot) of flow in the pond. Do you think this is viable? what about having a daphnia colony with a betta? Do you think this will just result in him eating till he dies or all the daphnia are gone?
Any fish with the daphnia will end up with no daphnia. I have tried to do what you want to do. It's a lot more complicated than you think. Like how do you circulate the water without losing the daphnia etc. I haven't been successful pulling it off yet.
Thanks, Yeah I suspected it would be a problem but thought maybe one betta wouldn't keep up. I will consider other options for my pond, thank you so much.
Do you have any idea how to quarantine wild daphnia? I have a growing Creek Chub I'd like to keep, and feeding it Daphnia seems like a good idea for just a 1-1.5 inch Chub. Also, I did catch in the wild, thinking it was just a regular minnow, which is why I would like to feed it daphnia.
+mats lunmbard The only way I can think of to quarantine them would be to catch them. have them lay eggs then move eggs to another pond to raise up. But that would be so labor intensive and difficult that it wouldnt be worth it. Most people would just feed the wild daphnia.
+Aquarium Co-Op thank you, i was just worried of some invader, but thinking about it, i did catch him in the wild.
Could you send me a cup full so I can start a culture? Actually all my tanks are freezing up now so I would have to start it in the house. Yes I would be willing to pay shipping and what you think is fair for a cup or so...
do they need water change or not and how much?
Can the daphnia be frozen for later feeding of fish?
wonder shell and Cyclopes? can anyone explain
What kind of shrimp was that and why is it in there?
can you tell me how to make an optimum environment for them please would really help me
ben birkett It's mostly in the video. Large volumne of water, pH above 7.0 and keep the hardness up. Then feed them appropriately and make sure there is enough airation.
+Aquarium Co-Op how do you prevent mosquitto larve?
I read that you can use daphnia to eat volvox in shrimp tanks. Do you sell daphnia? I didnt see it on your website. Thanks
Eric Luna None currently for sale, I've let the cultures go for the winter.
Are there any known Daphnia parasites that may be transmitted to fishes?
May i ask what type of yeast you feed these Daphnia?
Is it a good idea to start a culture of daphnia in a tank with a betta? Will the daphnia end up overfeeding the betta?
Typically the betta will just eat all the daphnia.
Aquarium Co-Op Thank You
cory, do you change water? if yes, how often?
What is the purpose of putting duckweed in the daphnia culture?
+T M to convert the ammonia the builds up from their molts
Are these daphnia magna?
Did you have heater? My water in the basement without heater is 17c. Do i need heater?
+Carchitecture You should be able to culture them at room temperature. The temp can change the rate of reproduction, but I'd say for ease of use just do room temp.
Aquarium Co-Op Are you starting up your Daphnia tanks again this year and are you going to experiment with adding some plants to them (besides the duckweed). Did you add the duckweed to help filter the water? Thanks for this video!
You should remake this video with better quality
how to u prevent mosquito larva?
Noticed you keep shrimp with our daphnia. What kind of shrimp?
some cherry shrimps.
That is interesting since I thought that the Cherry shrimp needed really clean water to survive in.
im soo confused sir where can i find daphnia do i have to buy it from the pet shops??
Typically you'd buy it online or find it in nature.
Can I put daphnia in my five gallon tank?
You can, but it's easier to culture with more water
How to feed daphina
What net are you using?
is this pulex mix with magna?? u willing to sell me a starter culturer?
I don't have this culture anymore unfortunately.
+Aquarium Co-Op that's sad. lost my magna culture due to rain water washing them away outside. not even sure if there is anymore resting egg at the bottom if the tank.
I have question. in my daphnia tank there are lot of white thing (seem looks like daphnia) at the bottom of the tank and they are not moving. Some of them are sticking on the wall. the daphnia also create some mucus/slime at the water surface. is it normal or should i remove the white thing or should i make new colony?.
You are probably seeing the product of daphnia molting
where do you get the daphnia to start? feeder daphnia?
Local hobbyists or Aquabid typically.
Where do you get your daphnia?
