GreenWaterFarm Daphnia Magna Eggs Live Fish Food for Hatching and Culture Suitable for Feed Betta Fish

Why did you pick this product vs others?:First off, it is not a capsule as they state on the site; it is more of a vial with a cap. A fair amount of eggs get stuck in it, so basicly you have to dump, then put the capsule in the water to get the rest. Not that that matters, as hatching was a no go. Not one hatched. Complete waste of money. Should have bought live. And to make that worse, you can not even get a refund when it does not work! I will never make this mistake again.

I read the reviews before I bought this product... even though most are bad, I decided to try it anyway. So far I am having a great hatch rate. I just think other people may not be experienced with hatching daphnia. It is best to used aged water with some tannins. After hatching, I am just feeding spirulina powder and fine yeast. After two weeks of hatching half a capsule, my daphnia are having babies! Great fish food for my Scarlet Badis.

Delivery was prompt, but that's about all I can say for this. Used both capsules, which are easy to open to add to hatching tank. Of both capsules, Ive had ONE egg hatch of the thousands that were included. Followed the instructions, and have no issue hatching other eggs from other manufacturers. I won't be ordering from them again.

The media could not be loaded. Started my colony in a clear vase (~16oz pasta jar on the left for size comparison) using aged tap water instead of water from my fish tank so I don’t introduce any unnecessary microorganisms into the daphnia colony. I set it up by a window that gets indirect sunlight.I added:1. Cuttings of houseplants that I know will root in water to act as natural filtration.2. 1 small ramshorn snail as clean up crew.3. Bits of torn catappa leaves to promote growth of infusoria which then provides an additional food source for daphnia.4. Air stone with water pump for aeration. Adjusted the air stone to medium size bubble at a medium to rapid flow.5. Added about 1/3 of a capsule of the eggs to start a small but steady colony in this small vase to hopefully prevent colony crash.They hatched after several days. Counted about 12-15 of them (there could be more but too tiny to see). Fed them spirulina powder and garbanzo bean powder mixed with water into a soupy consistency. I feed only 1-2 drops of the mixture every other day using an eye dropper. Before feeding, I changed about 1/4-1/3 of the water (will probably change the water less often once the system has matured a bit more).2 weeks later, they have multiplied quite a bit. Too many to count. Possibly over a hundred or even more. And I still have all the extra eggs I didn’t use in the fridge for backup in case this one crashed in the future. But let’s hope it doesn’t.Overall I’m very happy with the purchase and would recommend it to anyone who is interested to start their own colony. I’ve thoroughly enjoyed the experience. They are fun to observe! Best of all they double as pet and as fish food 🤭.

These did not hatch. We tried two different ways (with each capsule) and were very careful to follow instructions, but these did not hatch. Since the item is not returnable, nor was there any offer to replace it, this was a waste of time and money.

Update: it’s 7 days later (03282023 11:50-ish pm) and the hatch has started. Water temp 60-70, I used pond water and maybe 1” (maybe more) water changes with filtered well water, stirred the first 2 days with a beater (electric), left the light on for a few days and killed off the algae (oops), added less than a cup of rain water with algae in it and switched the light off at night, lots of spraying eggs off the sides, moved out side when it was sunny and warm-ish out. I added a few grains of miracle grow thinking the algae needed a boost but later found out algae is like most all plants that need a day and night cycle to survive. I’ll post a picture once the hatch endsOriginal posted review:Arrived in the mail box and the Box is really nice and direction are really clear on the back of the box. Contains 2 very full dry vials of dried daphnia bodies. Each body contains 2 eggs (see third picture) I used only a few small sprinkles since there are so many included in each dried vial. I still have one unopened vial and one 95%+ full. One vial would be enough to supply an entire pond (earth/natural pond) maybe even more. I’m starting a batch in a 2 liter soda bottle with the top cut off and filled with pond water. What I used out of the vial Should be plenty to seed my 3,000-5,000 gallon (estimated size) backyard pond.Batch Started 03/24/23 12am.I will update pictures as they hatch and fill the container.With good hatch rate this item should be enough to seed my pond after winter for a few years without having to farm seeds (eggs) myself.Thank you!

Took a lot longer than I thought to get going but I think that was because of me obsessing and doing water changes daily. Once I kind of gave up and left it alone the population really took off. I'm feeding them a mixture of yeast and spirulina and only changing water once every 2 weeks now. There seems to be more and more in the jar every few days now. Maybe a little suggestion card for best practices in the box would be helpful for idiots like myself.

Unfortunately none hatched, I have a "green tank" with great water parameters and followed all directions on the package and thought this would be a great environment and an easy start. I am 11 days out at this point and just don't think they are going to hatch. I will update my review if something changes and they are just "late bloomers".
