it's a lovely jar aquarium ... however, daphnia are tricky to sustain and in my experience require more water real estate and actually like algae and green water. Still, i hope you succeed. Strongly consider feeding them a few drops of dissolved spirulina powder, which you can get anywhere. good luck!
I'll keep you posted and let you know how it does!
I went to a river and collect materials and placed it in a jar. Successfully bred them in 2 days, i added rain water today slowly drop by drop not all at once because due to evaporation and the plants i lost about 3-5%
Follow up with feeding of daphnia. Colony stability. Harvesting and feeding. Great hobby within a hobby
will do!
So glad to have found this! Thank you
Life, finds a way.
Subscibed for the update. Nice setup
Absolutely loved the video. Looking forward to at least 2 more updates on this :-) Let me be greedy.
I will for sure! Just a matter of when I have time lol
@@JarsAndTanks Aah I wish you always stay busy because otherwise it's not good. 😊 Thank you for your reply! I'll wait patiently.
Love your setup! I’m working on doing the same, got a few daphina on some of my aquarium plants. Where did you get your daphnia?
If you had a substrate you could grow also blackworms. And perhaps tubifex, although these prefere lower temperatures🦊
That neon tetra is well fed damn !
I think it's egg bound
Good idea.
Thanks!
This video made me smile :D
lol thanks!
Lovely setup. Keep in mind to add a source for calcium carbonate (supplement directly, clam shells, egg shells, limestone etc) if your water is soft, as all crustaceans need it to molt and grow. Would be a bummer to get the culture limited in growth because of that. IME daphnia can be a bit sensitive to low oxygen, so doing some water changes can help (or if you're using tap water, coldest possible poured violently into a container, so that the oxygen rich splash can sink to the bottom where there's least about of oxygen and help mix it a bit)
What a lovely video! I'm going to try this. I will add an air supply line without an air stone for oxygen. Only, you showed a video of salvinia and called it frog bit. Brine shrimp are very easy to culture. They are totally salt water, no fresh water needed. I grow only enough baby brine shrimp that I need for 1 feeding. It takes about 24 hours. When I have fry, I do a batch daily. As the fish get older I do a batch once a week.
Good deal.
thank you!
With the stick on pellets, I find it easy to hold them against the glass until all the air is out.
after dipping in hot water? or without doing that?
No need to dip in hot water
Thank you!@@andyviet2598
If you regularly collect daphnia from the jar, then I don‘t believe that it will be self-sustaining. But you could add to it some fish vaste each time when you clean the gravel in the fish tank. Some feed daphnia with yeast.
Having harvested daphnia from a rain water butt outside in the UK (during what we call summer), I'm really not sure about needing to heat your jar!!
Subscribing for the update
Thanks! I'll try to have one sooner thank later, I'm already adjusting a bit from my original plan lol so there are definitely updates to come!
Bagus sekali ekosistemnya di wadah
Thanks!
what about a higher jar with a deep substrate, and building in it a diverse food net comprising at least daphnia, cyclops, blackworms, and tubifex? This system could be fed with fish vaste collected when cleaning the gravel, and with yeast. Bran also contains yeasts🦊
Under the high substrate there could be a so called „plenum“, see videos of Dr. Novak and Prof. Jaubert.
Oh I love that! Yea one thing about me is my original plans never really stick because I can’t stop tinkering with things lol one change I’ve already decided on is I’m gonna be feeding it rather than leaving it as self contained and I can definitely see myself adding some if not all of this as some point 😂 I’ll check out those videos though, thanks!!
you could also add some shrimps to this system🤡
I would suggest a thick substrate, so that at the bottom you have room temperature. This because tubifex do not multiply at high temperatures. Apparently they reproduce well when kept in the fridge.
Further if using tubifex you need a trustworty source, to make sure that you do not import parasites🦩@@JarsAndTanks
Tall jars are probably a bad idea since the water will stratify and be oxygen-depleted at the bottom. Width increases air:water surface ratio in a really good way to prevent low oxygen. Regardless of how attractive tall cylindrical shapes are, it's probably the worst for aquariums.
Indeed👍 I totally agree that tall aquariums have the poorest oxigenation🦩
Further, denitrification substrates(see videos by Dr. Novak or Prof. Jaubert), if installed in such tanks, are known to be oxigen-hungry. Although these can keep a prestine water quality, as shown in the oceanic aquarium of Monaco and in various youtube videos, they can drain all oxigen out of the water and cause catastrophyc failures, especially in the summer👹
But you could add a USB piezo airpump with a solar powerbank🤡 Or keep just animals that can breathe air, such as Bettas🐸
A high jar would allow you to confortably install a thick substrate and a plenum (see videos by Dr. Novak or Prof. Jaubert). Here low oxigenation in lower substrate is key for achieving denitrification. Keeping in mind that such a substrate with plenum could be 10cm thick of higher(~4 inches). I believe that this could be the best possible aquarium for a lazy labirinth fish such as a Betta🙂 Of course some options for hanging arround efortlesly close to the surface should be offered🦥
Then again, this video was about keeping animals for live food in a jar🍺 So yes you would need an active strategy for oxigenation if yout jar is tall🌊

@@andibandi1190 the cheapest airstone + airpump combo you can find is probably way more oxygen than you'll ever need in just a few liters space for daphnia. The USB pump + solar powerbank doesn't sound too bad, though ideally you'd want the jar in a north facing window to avoid it getting too hot when the sun shines in on the jar. It will churn the water and prevent stratification in addition to adding all that oxygen in such a small volume of water. I personally wouldn't worry about having a filter if you have other stuff with surface area in there.
What are you feeding them besides algae or moss. Are these things enough for the daphnia?
essential if have a fishtank. nice set up . mine just in a bottle with junk in bottom, this ok with no air or water flow? I have a small airstream with no airstone just to keep water moving
I’m thinking I may add a small sponge filter and maybe even some fairy shrimp 🤔
@@JarsAndTanks cool. im actually trying that at moment more like yours and with the shrimp , scuds? . its going to be difficult to not end up with 20 jars :)
@@rodd555 I actually don’t like scuds because if they ever accidentally got into my shrimp tank they would cause a problem for my baby shrimp and would be impossible to get out once they’re in, but if you don’t have a shrimp tank to worry about they might be a great option!
@@JarsAndTanks i saw somewhere about this. was hoping to keep seperate. I have jar set up but not ordered them yet you may have talked me out of it as not worth risk. do have shrimp so going to have a look at fairy shrimp. thanks for the heads up.
BTW, great video🤡
8 and half minutes of musics in background - it is unbelievable
🥁🎶🙉🎶🥁
what kind of frogbit is that? cause mine each leaf is a half dollar size.
Ya know, I was told it was frogbit when I bought it, but now I'm realizing I may have misidentified water spangles
@3:08 Frogbit? I think those are Salvinia minima
I think you’re right lol
Derp happens 😁@@JarsAndTanks I have Salvinia minima in my tanks, like A LOT.
Those little floaters do an amazing job at keeping the water stable and they multiply like crazy. Good thing they are not as annoying like duckweed to remove the excess.
Follow up?
Super cool, but they are gonna crash that gar in under a mnth my dude. They breed way too fast. Gl though! 💯🤙🏼
Lol well breeding fast might be a good problem to have for me since I’ll be using them for live food! We’ll see!
Why not culture fairy shrimp? They’re just fully freshwater brine shrimp
Great idea! I think I’ll try that too and maybe see how they compare
but daphnia eat algae... so you need to get rid to of too many plants. The more algae the more plumpy looking these daphnia be...
„Live food is the best nutrition for fish“ is Dogma🤡
I have to disagree, I know the alternatives are fine but I think it’s a lot more stimulating for the fish when you can provide live food and it brings out the fishes natural behavior which is always interesting to see!
from the video I understand that your theory is based on Hollywood movies. That is fiction🤡@@JarsAndTanks
Looks like moinas not daphnias
those are magna daphnias
brine shrimp is saltwater species, fairy shrimp is freshwater species .... no need to mix them up, also that is not a frogbit.. probably its salvinia
pretty useless. No proof that this actually worked. hey, show us that you didn't kill them all by feeding too much.
If only there were an update video… oh wait
Vegan food is better🤡
lol and what vegan fish food would you recommend?
vegan cat and dog food might work🤡@@JarsAndTanks
these are just ideas (I did not have the possibility to try them out, otherwise than on myself🐸):
chickpeas, soy, beans, lentils, as well as mushrooms are known for the high protein content. I would cook these with garlic, sea salt, and perhaps some algae (marine, like Nori for Sushi, or Spirulina).
Blend or use a food processor, then let the cocoction dry, for example in a food dryer.
You could also spread a thin layer on a pancake plate🤡
And there are also those basic rice cookers that keep the food warm indefinetly, at 60*. Within a few days it will be dry👻
There are actualy Spirulina tablets with high protein content on the market.
Flavoured Tofu? I hear that fish like garlic.
And for plant eating fish a vegan diet should not be a problem.@@JarsAndTanks
I think that at a second glance, attempting to feed your fish a plant based diet actually does make sense. A common death cause for carnivores is cancer. I saw videos of Betta fish with tumors, very sad.
There is a popular book „The China Study“, detailing the correlation between meat diet and cancer development.@@JarsAndTanks
… on the other hand, fish do not want to be fed, but to hunt🦥
below is a video about establishing Tubifex in the substrate of a fish tank.
Tubifex züchten - Das einfachste Lebendfutter der Welt
on AquarienweltTV
th-cam.com/video/WK7U4a0qQk4/w-d-xo.html
The main information in the video is that water temperature should be no higher than 23-24C*
I know that at high temperatures Tubifex do not multiply, and that apparently they reproduce well when kept in the fridge😝
Thus I would suggest a thick substrate, because at the bottom you would have room temperature, even if the water in the tank is warmer🦊
Then, blackworms do not have a problem with temperature, so in the upper part of the substrate you could have these🦩
