@@BlakesAquatics Can daphnia eggs be dropped in aquarium with fish? Will they hatch? I don’t see anyone else asking this so I’m sure it must be a dumb question.
I started my cultures by buying a live pack from my lfs. I dont have any aeration in my cultures,they live in windowsills. I thought I had lost my cultures over winter (in UK) ,but when temp increased in spring the jars sprang back to life. Fingers crossed I can manage to keep them going for a 3rd year.

I agree with everything you shared. I personally had more success using larger aquariums like a 20 gallon or larger. The larger the volume of water the larger the yield of Daphnia and more stable water parameters. I also do a 20% water change a week or bi-weekly.
I have a 3000L hydroponics tub I use to culture daphnia, bloodworms and other critters. I've found over winter the daphnia die off leaving their eggs to hatch out when it gets warmer. Usually we only have below 18° weather in winter so usually only 3 months of no daphnia. Blood worms usually go year round
Thank you this is really helpful! I'm getting a betta in 1 month ( tank is already cycled) and I wanted to feed some sort of protein rich food. This seems like a good option for a planted bowl im planning. Definitely gonna subscribe
Hey, great video. Well done. We are successfully culturing daphnia magna in 3 vessels. We've watched a lot of tutorials -- yours is right up there with the best. But what we're missing is how to change the water without losing the eggs on the bottom (mixed in with snail poop, algae, and other muck). Yeah, we're keeping 2-3 pond snails in each vessel just to help keep algae growth in check. It seems to work, but we still worry about changing out the water. Any help appreciated. Best wishes.
As he said.. Don't overfeed.. Also.. Water Changes are a must. Feeding fouls the water or grows daphnia pretty fast. That means you need some new water to take away the wastes and ammonia, etc.
Given, you can have 10 times as many adults in a matter of weeks.. Then, you have 10 times as much food being processed. People can hardly comprehend this, so it becomes a problem. A few drops becomes a few spoonfuls. Before you know what happened, they are all dead. So, keep removing them to feed your fish. And, keep syphoning out some water.. You can swish a net in the bucket or dump it thru a shrimp net.. to get the syphoned daphnia. This is Why they Crash. You can also crash it by feeding before the water clears.. Rotting food creates a bacterial bloom. (gets even cloudier and stinks!)
I have attempted the magna culture many times and failed many times until i started culturing green water. I have cultures last years now without feeding them anything other than the green water every few weeks.
I just came across your videos, lovely to the point and very informative videos 👍👌 If you have the time, i would very much like to hear about doing combo with dapnia and blackworms... Is it "just" to combine your two videos tutorials in one tank? Is there anything to be extra aware of? Thank you 😊
No not at all, it just makes sense to me to do that. More live food for the same real estate. The blackworms help further break down the discarded food and shell from the daphnia. Win wkn
thank you for sharing this video. where are you sharing this from? I am trying to guess based on your accent but sometimes I am can be very wrong, so you tell me.
I was reading an article on micro plastic Blake. They said they are seeing this in Daphnia, so it is probably an idea to let their systems flush out. Fry that have been found ingesting micro beads, are often lacking the survival instinct and can affect their sexual development. Just a thought!
gets too warm in sumer here, but this time of year I can catch them outside in tubs of rainwater I left over winter. So I do my breeding this time of year too, I find live food a great primer to getting fish to breed..
No one likes my live cultures here at my house 🤣 Still have them hidden places though. Ordered some of your 3d prints today. Excited to get them, but no rush ✌️🙂
@@BlakesAquatics if you did use some kind of filtration, would 200 nm filter cloth cover it well enough to stop the Daphnia from being sucked in? Or something slightly larger?
Daphnia feed on bacteria stuff, that’s why yeast is a good food it’s a live bacteria. You don’t want to remove all that from the water. Just use a turkey baster and get a few siphons from the bottom and add some more water.
I used IBc tanks and I get a tablespoon a day to feed my fish. I am in Australia. Life food for 8 months of the year and feed the daphnias every third day.
do you mix a specific amount of spirulina powder and yeast per specific amount of water in preparing food for live daphnia? thank you for this great video i’m going to attempt culturing scuds and daphnia together
I've been feeding my daphnia culture yeast, but the whole scape and glass ended up getting covered in the fungus. What do you recommend I do to remedy this? Do I just wait? Is there an organism I can introduce to clean it up?
I got the instructions that i could feed daphnia only with spiruline once a week. Have you tried that, is it fine? Or is this mixture that you are showing in this video better? If I would use your tehnic, how many times per week should I feed fleas? You said in the video that to much food is critical. While in the beging of a video you are showing much food on the floor of the tank with daphnias in its near. Why do you think my daphnias swam first day quicker and now there are slower? Why they are swimming faster in the tank than in a big jar? There is also something on the floor. Is that possible that would be dead daphnias, after a first day that i got them and when i got them they were a live? Thank you for your answers.
Hey Blake, would it be possible to culture daphnia and scuds in say a 40 liter tank together? And possibly blackworms as well? I was just thinking variety in 1 central location thank mate🙂👍🏻
1L would be a huge batch, i wouldnt recommend that because you really only want to feed the yeast mixture for a couple of weeks. id only make up 100mL or so, 1/2 tsp of each yeast and flour
@@BlakesAquatics Thanks. Appreciate the quick reply. I gather water changes are still required. If so, I assume a fine cloth (eg handkerchief) over the intake of the suction hose is used.
@@madmax1412 i just water change via an ordinary gravel vac along the bottom of the tank. Helps pick up old shells and most of the living daphnia are up toward the light

I have found daphnia great as a food source but I wouldn't put them in the same tub as ostracods (seed shrimp), because the daphnia do eventually end up eating them.
I usually buy live food, sealed in a bag. Currently have 3 small fish so the fish can't eat the entire content of the bag. Can I split the bag into two by feeding half one day and the second half of daphnia a few days later? That is, will the rest of the daphnia survive in an open bag?

Hi Blake, thanks for the video. I will be in Lismore, NSW, Australia during Oct to Dec, and will need a constant supply of live Daphnia for 4 weeks. Please let me know if you sell them. Otherwise, please let me know the best and cheapest place to get them.
I don't think that these are a parasitic creature in my tank, but I see little creatures running around their shaped similar to lice or shrimp, but they're super super small as long as they're not attaching to my fish. Is that daphnea that I didn't try to culture and it just happened? It's a planted tank I've had for about 2 years. I got it from a friend. It was completely dried for 6 months before I got it, though I did get some driftwood from her that they may have attached to but I didn't intentionally add them. I don't know if they came with my live plants but I haven't added anything for over a year and just noticed them now after I was looking for Cherry shrimp that are no longer there. Although I still have a ghost shrimp colony

There's no way to flush it out completely unfortunately. Microplastic is in all bottled waters, tap water, even rainwater and snow.

Very helpful video thank you. How often do you need to change the water?
Maybe 10% or 20% weekly. Its also a good idea to remove shed exoskeletons from the bottom

A two liter container is enough to keep daphnia and to breed them?
10L bucket would be better as a cheap option
Brilliant video! Is there any reason why you couldn’t use a sponge filter to help keep the water parameters in check?
Smaller bubbles and the daphnia will get sucked into it
@@BlakesAquatics if you did use some kind of filtration, would 200 nm filter cloth cover it well enough to stop the Daphnia from being sucked in? Or something slightly larger?

Would adding a sponge filter with some pothos fix the water quality issue?
