How To Feed Your Daphnia Culture

This video is dedicated to the most crucial element of maintaining your daphnia magna culture without a crash.
1) Pay Attention to Water Clarity
2) Observe Overall Position Of the Daphnia - walls vs center
3) Change water Weekly or Bi weekly - depending on overfeeding

Just started culturing them, mine were on the walls, thanks for the info, you just saved me a lot o trouble!

[@augustvukosovich4683]

Fascinating. Thank you.

[@JhunDumsTVXj]

Wow very nice idea.

[@Nice-Poeci-Fancy-Guppies]

Thank you very much

[@hannakralovetz1401]

Thankyou.

[@AquaticDomain]

Cool Video! I have a 29 gallon with a few floating plants and I have a few questions. Where did you get your starter culture? I was going to catch some wild ones. Also do you recommend dry yeast? I noticed they sell it at Walmart. Do you a specific ratio of yeast and spirulina powder?

[@kukukaka968]

thanks wall trick is a good way to know

[@archibaldbean7491]

Do you need to aerate the tank, or is it fine that way?

[@UserNotFounf10101.]

I have like a bunch how do I change water they keep nearly dying

[@NuclearButtonz]

Great information most people don’t go this in depth! Love the live plants in their tub, do you think it helps keep them alive? Also gorgeous fisheys and tanks!

[@Nice-Poeci-Fancy-Guppies]

Thank you very much- no the plants just get in the way but tell me about the water parameters- since hornwort can grow very quickly with a lot of nitrates in the water

[@M29WeaselDriver]

What yeast do you use?

[@spit-fire]

You taught me some stuff cool

[@Nice-Poeci-Fancy-Guppies]

We can all teach eachother

[@seamus6994]

I have a bunch of eggs to culture. It's been awhile since I cultured some. I have rather big tanks, and was surprised that I have daphnia still in my tanks. I found some in my filters and at the bottom of the tank. It's been MANY months since I added them. Strictly as a food source, but some have found a way to survive. Even in crystal clear tanks.

[@Nice-Poeci-Fancy-Guppies]

Yea you know I had tried to do this but my aquariums are so loaded with guppies or endlers that they never have had the chance. I have left small colonies in a few uninhabited 5 gallons without food for months at a time and also there will always remain a small amount without this type of feeding.

[@kennethliew888]

No need water change?

[@jamesdduong]

This is an amazing set up. Thanks for sharing! What temperature range can daphnia handle? I want to do an outside tub like this with a heater. How many gallon is that tub and how much water do you change weekly?

[@Nice-Poeci-Fancy-Guppies]

Yo thank you- You know I dont use a heater at all and I keep my house thermostat around 72-75°F (guesstimate water temp stays between 70-75). I think the tub is about 40 gallons filled the way I have it in video -50 gallons roughly if filled to the top. Ive read that daphnia can do much cooler temps which wouldn't surprise me considering how remarkable they are, but have also seen that they flourish in most of Asia where its also very warm weather. I change the water about once a week ~50-70%. Changing the water weekly will definitely compensate for any overfeeding and save you from a crash. And when they crash- make sure to not throw them all out- if you catch the crash early enough and strain the water for the "bodies" and mulm on the bottom back into a new fresh water,, sometimes they literally come back to life as well as all the eggs they leave on the bottom - very incredible species.

[@CoffeeTimeBrian11]

Very useful! Wow! Didn't know they create their own hemoglobin. Interesting crustacean.

[@CoffeeTimeBrian11]

Do floating plants help?

[@Nice-Poeci-Fancy-Guppies]

incredible little things

[@Nice-Poeci-Fancy-Guppies]

tbh i feel like alot of the plants die off from the bakers yeast and / or hair algae needs to be controlled. In the end they all have some duckweed on top that has to be cleared weekly so i dont think it hurts them at all.

[@hendriyahya7995]

I feed my daphnia with 2 glass green water from my goldfish tank which i put it outdoor.

[@russkiebetta]

Thanks for the great video! Very informative. I've heard that some people are adding soy protein in the food mix. I don't know if it's any good tho. I've been trying so hard to keep my moina running but first culture crashed after 1 month. Second culture cushed second day. Tomorrow I'm starting 3rd one. If i understood right, 1 cup of water 1 tsp spirulina, and 1 tsp yeast correct? Do you filter the mix when adding to the container? Or just spray it directly even if you get some (un-disolved) powder in the feed? Lastly are we supposed to clean the bottom of the tank/container from mulm when doing water Change?

[@Nice-Poeci-Fancy-Guppies]

Yea - its tough- they crash. You have to change the water and feed just perfect and even then sometimes , who knows what happened. Get em while their hot and try to keep backups always is the only advice I can give. I wouldnt feel too bad about crashing them, its literally part of their life cycle and how they drop eggs vs live birth tells us how well we are doing.

[@kkutube1972]

Against the wall, need to feed. Thank you. Mine is always on the wall so I better feed. I am going to feed and come back to your video because mine is white. Thanks.

[@Nice-Poeci-Fancy-Guppies]

Its an art - take your time increasing food to make sure

[@kkutube1972]

Do you use a sponge filter or just an air bubble? It does not seem like you need it in your drum. Thanks.

[@Nice-Poeci-Fancy-Guppies]

I dont use any air at all. I think if I had a larger container without any plants I would use air - but ive done just fine without. I use air for brine shrimp but not daphnia.

[@nodatastored684]

❤

[@video_phone]

What kind of plants are in your tank? I've had my culture for about 2 months and i want to add plants just because.

[@Scouse.raver1]

It's hornwort and duck weed

[@brandonlasvegas]

[@charleswilson8038]

👍 👍 👍 👍 👍

[@nickbrandimarte8657]

Badass.

[@Nice-Poeci-Fancy-Guppies]

Thank you!

[@mcliloldbigyoung]

I have a question and I hope I'm not too late asking, how do you do water changes without sucking up or scooping up any daphnia, I currently have a baby snail takeover in a lot of my tanks and it forces me to use cheesecloth or gauze on the end of a gravel vac so I'm not picking a hundred dirt sized snails out of each bucket, I just got some daphnia for two tanks one to culture, and one to feed on a suspended algae bloom, I'm curious how I'll do water changes now without disturbing the daphnia??????

[@Nice-Poeci-Fancy-Guppies]

I put a fish net over the intake of the gravel cleaner with a rubber band or hair tie and keep the hose close to the ground level of the aquarium. And I use the thicker mesh net, like the white one that isnt as see through.

[@mcliloldbigyoung]

@@Nice-Poeci-Fancy-Guppies thank you so much, you're a life saver, that's a great idea!!!!

[@neon8688]

hi can i ask what guppies are those,i have many but idk what their line is

[@Nice-Poeci-Fancy-Guppies]

Yo! So the guppies in this video were the first generation of a cross between a 1/10000 staeck endler and a meijin li double swordtail line that i called "starburst swordtail guppies" which I then crossed again with some albinos and turned the line white purple pink and even this metallic chromatic purple phenotype. Its pretty cool how many of us can be doing the same breeding practices and end up with very similar results in different parts of the world.

[@Munna33718]

How to make the feed in detail please

[@Nice-Poeci-Fancy-Guppies]

Add 1 teaspoon of bakers yeast to 4-12oz of water in a water bottle - close the lid - mix it up for 30 seconds and Voila. pour it in the water. Also the amount you feed depends totally on the amount of daphnia you have to start. if you have 100 daphnia start with smaller amounts of yeast and take note of how long it takes them to clear the water. once you have a substantial mass of daphnia begin to increase the amount of yeast you mix.

[@zeroarnado5735]

Your dapnia are big, but mine are small. How did you make them big dapnia?

[@Nice-Poeci-Fancy-Guppies]

I believe this is a different species, Daphnia Magna, I presume you may have Daphnia Moina, better for numbers, fry and smaller fish.

[@signupisannoying]

I'm amazed you don't have any copepods (cyclops) in there. I find it hard to get rid of them.

[@Nice-Poeci-Fancy-Guppies]

Yea you know Ive read a lot about it but I just don't seem to have that issue.

[@Tomjarr1]

How would cyclops get in the tank? Reason why I'm asking is because my daphnia tank crashed last week for the first time because I found thousands of cyclops in my tank. I keep my tank indoors. I talked to a guy who culture's daphnia and he said it came from the yeast I was feeding them. I find that hard to believe.

[@signupisannoying]

@@Tomjarr1 For me I got cyclops because I got my daphnia from a lake. But I managed to get a small colony of daphnia without cyclops now. I did it by transferring just 4 pregnant daphnias to a clean container. I'm also thinking of doing a "clean restart" from time to time by using a container that I know has no cyclops for sure, and then just transfer few daphnia over.

[@DavidGoneFishings]

what temperature do put them at? and do you add a heater in the winter?

[@tokking7836]

Are they too big for cardinal tetras?

[@Scouse.raver1]

Cardinal tetras will eat daphnia

[@Nice-Poeci-Fancy-Guppies]

No they are about the perfect size and the tetra will eat them quick

[@anarchy5155]

Can i feed them fish food?

[@Nice-Poeci-Fancy-Guppies]

I have used regular fish flake, it breaks down in the water and does work, just not as quickly or as well as bakers yeast IMO.

[@noorhussain6313]

What you feed them ?

[@Nice-Poeci-Fancy-Guppies]

Red Star Active Dry Yeast mixed with chlorella powder.

[@noorhussain6313]

I have yeast power only here and how bout the rice bran ?

[@jparks6544]

that's been the missing step. No one says exactly how to feed them and how "cloudy" the water shoud be.

[@ChristopherLecky]

TIP! Fish will eat just for the sake of eating ,,,,,its because they are geared to respond to the stimuli of movement !

[@66bigbuds]

No water changes. Just top off. They like stagnate water. no pump, no filter, no air, no sterile r.o. water they need calcium for their shells and high ppm would be better than r.o.

[@stevensam9786]

Looks like a infestation

[@tonyfrench2574]

Incoherent, rambling, nonsense

[@Nice-Poeci-Fancy-Guppies]

ty very much
