I watched like six of these in the last hour and this is the best one very educational well spoken clear and well understood I'm subscribing

It's amazing how many different approaches you can take to culturing daphnia. This is fairly close to what I do but I like to mix things up and add some colorful vegetable matter to my yeast solution and let it sit out for a while so the yeast has a chance to absorb it. This helps provide a more balanced nutrient profile and can also help color your fish. This way you can indirectly feed things like beets to your fish. If you actually put beets in your aquarium it would turn the water color but the daphnea just eat the colored water and turn color a bit, which is pretty cool.

I dropped a few Moina into a planted fishbowl that had a persistent green water problem for months that I couldn't get rid of even with 200% water changes and blackouts. After only four days, the bowl was teaming with them and the water was crystal clear. I couldn't believe my eyes! I put one of my female Endler's livebearers who wasn't eating very well after her last batch of fry into the bowl, and she's been gobbling them up very happily.

Thanks for the video. I think I enjoy these videos so much because I have been around a few keepers that will tell you what to do but not how to do it. thank you for connecting the dots... or daphnia. HA!

Look forwards to tuesdays,great channel,Thx Rachel!

Love it! Thank you for the needed detail. Have been culturing brine shrimp and this seems far much easier!

I am so grateful for you and all your knowledge you share with us

This is so informative! Great job, fantastic reporting!🌻🌼🐝 Keep it up 🙌

Thanks Rachel. The explanation you gave about preparing the yeast was extremely helpful to me. I am going to try to culture daphnia again.

One of the most, if not the most, informative and clear explanation on Daphnia! Thanks... Im gonna try my hand at some Daphnia culture tomorrow! Thank you!

Awesome! Thank you for the video Rachel

Great to see another fish keeper into the tiny fish species.. the smaller they are, the better I like them. Also excellent info on daphnia culture, which is not difficult but also not bomb proof either. I'm a huge fan of live food for fish, as many different ones as I can find and culture in a small apartment. Nicely done !

Great video. Love the shirt, Joey would be proud!

Great video, learned a lot, never tried to grow (culture) my own Daphnia, but after watching your video. It doesn't seem so daunting a task with a little work and practice.

Thanks for the tips, green water is difficult to maintain, I'll go the the shop and buy some yeast :). Also if you use an air pump with fine bubbles, indeed they get stuck to the side of the tank an die. Great video.

So I am late watching this video. It is four years old now. I wish I could say I’ve seen it before but my memory is not as good as it used to be. I think it popped up because I just recently bought some and started my own culture. Love your videos. Even the older ones.

Very helpful video 👍 😊

very good vid, Rachel. I only have guppys but I got a spare tank, where I'll be testing out some kinds of diy filtration. I think I'll try to culture daphnia there in your way, when doin sponge filter testing... thnx

Thanks for your video

I maintain decent cultures of them in big buckets (around 100L each) on my balcony. I cover them with a mesh, so that mosquito's can't lay eggs in them, because that would flood my house with them. I feed them bird poop. I have 3 parrots (healthy, so no parasites) and their poop will dissolve in the water, stimulating the growth of floating green algae (green water), I believe that is their natural food source. The more sunlight, the better it goes. These creatures are amazing. Even when the buckets freeze over during winter, they will emerge again next spring. I advise everyone to read up on these amazing critters, their life cycle is quite interesting. If you want to feed them to fry, you can buy a seeve set that has multiple sized seeves that you can stack. This way you can separate the smallest ones from the big ones. That way they are a great alternative to artemia naupli.

maybe a asked my question a little too soon, ... i wil try a drop system to my waterchanges, maybe that wil help (still learning :).... ) : I found this on fins.actwin.com/live-foods/month.200102/msg00014.html "........ You seem to have "liquid rock" for water! My water is about 400 ppm hardness -- slightly softer, but not by much -- and several species of Daphnids live in it OK. The trick is to VERY SLOWLY aclimate them to your water. Daphnia are sensitive critters -- that is why they are used for water quality testing -- and any rapid change in water parameters will likely result in stress and eventual death. I would recommend that you, literally, add your water to the starter culture drop-by-drop (through an air line with a valve or a knot) at least the first 50% of the fresh water. The slower you add the water, the less stress on the Daphnia, the more likely the successful survival. In similar situations I usually set up a drip overnight, so that I loose no time fiddling with adding the new water and the critters (crustaceans or fish) have an easy time getting used to the new water. ..."

Cool video. :) I found that Daphnia seem to do well in outdoor dirted tanks. I had set up a 50 gallon plastic tote in my backyard for some fish I wanted to breed over the summer, and after I removed the fish for winter, it got filled with leaves and dirt. Next spring the water went green, and it was full of Daphnia. I'm gonna try it again this year, and see if I get the same results.

Great video! I wish more people would talk about their experiences with daphnia and other live cultures. One note. Daphnia feed off microscopic food. If you can see cloudy water that could be more food than they actually need. In some cultures this could lead to a crash. But it sounds like you found a system that works for your needs.

Thank you.

Frank! I got my daphnia from him this past weekend

thanks u r very helpfull

Hi Rachel, thank you for all of the info you glean from your hard work. I do appreciate it. If you don't mind I have a few questions for you about the daphnia culture? Is a 10 gallon OK? It was free. Will my fish benefit: tiger barbs, gouramis, tetras, angelfish, Betta, zebra danios, Cory cats ? Do you cycle it like other fish tanks have to be? You have plants, don't recall what kind, but will rewatch video, so what kind of substrate then? How about a heater? What temp? I want to supplement my fish diet. Are my fish the kind that will eat them? Is anyone able to order from your friend Frank? If not, do you recommend anywhere? How do you do water changes without getting daphnia? A specific ph, temp? Sorry so many questions, but I am really serious about this! Thanks Rachel!!!😀

Warm water is better than hot for yeast :)

Great video. I may give this a shot. Although, like you, I think I'll be giving the manure and dead animals a miss. Lol

I use to catch these when I'd go fishing

love this video!! great i was able to find something clean and poopy-free. though im really curious about what you used, okay you said 20 gallon aquarium and a lamp i see. i also see some plants. but tell me is there a heater involved i really cant see any. please advise.

I just want to say this is a well explained video about colturing daphnea, my Congratz. I have an Aquaponics set up in backyard inside a greenhouse, have minoes, crayfish and soon catfish. I am really looking into producing my own daphnea for personal use and this video is so well done. Thanks!

Do your crayfish eat the daphnea, then? I'm planning to set up a dwarf crayfish tank soon, and was wondering if these would be a good live feed source. My main concerns would be how fast they are, how much protein they have(as apparently adult crayfish don't need as much?), and how one would get a good balance of this? Sorry for asking you, I couldn't find any info online as of yet. (And it's really interesting that you post this like a day before I really start looking for information on daphnea)

Hey Rachel, thanks for the very informative video. How important is it to get the bubbles on the top of the yeast? I can get it to go milky, but it never seems to bubble no matter how long I leave it, and I've tried a few different brands of active yeast. Also, when you say hot water - how hot is that? Lastly I read somewhere that daphnia don't do well in water that's been conditioned i.e. had Prime or other dechlorinators added to it - though obviously loads better than they would in chlorinated water! I forget the reference but I think the argument was that the Sodium Thiosulphate inhibited their reproduction. I wondered if you'd come across this in your reading or if its just another internet myth? I know you're on a well and don't have to dechlorinate, but hoped it might have come up in one of the articles you mentioned? Thanks again :)

Rachel, thanks for the advice. I'm finding when I use a sponge filter this 'clears' the yeast. Does this happen with your set up as it seems to defeat the objective of feeding the daphnia. On another subject is spiralina a suitable substitute for infusoria for young fry? Thanks in advance.

👋Thank you

gotta say i love that shirt XD

I add a bit of compost tea that has been boiled. I have had an outside culture I put some straw in and leaves fall into as well occasionally. I put a culture in my horses water trough to clean up algae so probably horse slobber in there. but dead animals and strait waste ... I mean the outside one is for the pond fish and the one in the horses water are cleaning up algae probably put some feeder fish in there to eat up bugs if any get in there.

hey Rachel love your videos just wanted to let you know you should keep feeding your daphnia Spirulina and other types of algae as yeast offers very little in the way of nutritional value and obviously using them as a live feed you want to be passing on that value to your fish.

I proof the yeast too, but I've always added the tiniest pinch of sugar to the water with the yeast while it proofs, to give it a bit of an energy boost as it comes out of its dormant state. I'm sure it's not essential but I do it anyway. Leave the yeast 'til it's foamy and bubbly and the sugar will be fully metabolized by the yeast, so there is no danger of adding any actual sugar to the tank. If I find my yeast has died ( it won't bubble up if that's the case) I use it to feed microworm or springtail cultures. The worms and springs' appear to relish any yeast, even if it's not alive.

+Karen J Gray I do that when baking bread, makes sense

i have an unintentional daphnia culture, its in a small heavly planted tank with no fish. the original water source i used for the tank was from the local resovoir. in the tank they seem to cluster around the bucephalandra

in my experience, I never like success culturing daphnia, but I kinda collect daphnia every day to feed my fish because in our country , daphnia are all over .

I've mentioned it before... one of the things I've found is that Dario Dario aren't able to eat them if the daphnia are too big (actually the little pigs would rather have white worms!). I've been working on a sizing method where I drill small holes (sized slightly larger than the feed size needed) in a translucent plastic container, clip it to the side of my culture tank and put a small flashlight or small light source there to attract the daphnia. After a while the smaller daphnia get through the holes. I use a turkey baster to suck them up and put them in a specimen container for feeding. Not a perfect system yet but it does save the reproducing females (they are mostly all females) and get the young "veal" daphnia for my boys!

I forget the smallest ones name but I've read it is too small for Dario Dario. My daphnia tank is on a lower rack so I just put the light to it and use a pipette to suck up the smaller ones leaving the adult moms to have more. I have what I think is a monia culture picking up pace so I'll try them soon to see how they go over. I'll try some mosquito larva too when I set up my mosquito trap. Just trying to vary their diet... so far they only eat live foods.

+Chuck Troast "looks like more of a supply house for schools" Exactly!! You may be surprised how many aquariums are maintained in High Schools and Colleges. This place is a great source of basic algae cultures, invertebrate cultures for foods, aquatic plants, etc.; all top quality. I kept aquariums in high school and earned money (and room for my personal aquariums) taking care of them in college.

Any thoughts about feeding paprika? I was told this works great.

1:15 😒 I prefer to do things a bit differently.... 🤣The look on you face when you said it though....

Eventually I'd like to get a tank or 2 to grow these.

I live in Florida and worry about the temperature they like..house is constant 78 degrees, will they survive? Thanks for your hard work.

I started growing 1 ( a survivor from 3 bags i bought thinking if i buy enough they would be able to survive in a aquarium with my fish. My fish proved me wrong in about 15 minutes) You are right about the green water. Ever since my 1 daphnia survived and i assume i have about 20 now, the green water has started clearing up. Instead of yeast i use protein powder that was meant for my consumption but i did not like the taste. Are Daphnia vulnerable to moderate to high levels ammonia, nitrates and nitrites?

Facinating information, I used to do this in Nebraska, but here in New Mexico it gets so hot...and where could I buy a starter culture of Daphnia? Thanks

Great video! Are you still maintaining and feeding daphnia? My killed my first culture almost immediately. I think I overfed them. I decided to setup 4 tanks this time including a 38 gal rubbermaid. If I crash one I have extra tanks that hopefully won’t crash. I’ve read they don’t do well with plants. I noticed you have plants so maybe that’s not necessarily true. I also heard you should drip acclimate them. Love to hear your thoughts.

Wow Rachel, i'm a new subscriber and I just love the information you have. Thanks for the detailed videos . I'm starting this hobby in the last couple years and loving it. May I please ask if it is bad practice to keep up to four different species together feeding different foods? the fish are eating the frog food, frogs are eating the female bettas food, bettas eating mollies food and so on.
