GREEN WATER FARM 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.

Decided to write a review because of how many bad reviews are showing up. This is absolutely a great product. It is a live creature, so the viability of the eggs is dependent on the fertilization and animals themselves. It also heavily depends on how you’re able to culture them after they’re alive. I purchased these little packs months ago, and they are still producing many offspring that I used to feed my axolotl’s. It’s a much cheaper alternative to Brineshrimp given the supplies needed and the time spent. I really just don’t wanna deal with salt water. 😂 Give them a try, but do your research initially and set up a couple different containers with different factors to enhance each container differently. One of them will eventually takeoff. I have a total of five different set ups and out of the 5, 3 have been extremely successful. Remember, they are a living organism. Online you find really easy ways to culture them without anything but water and food in an ugly little container or tub. I have live plants, substrate, and different food types that I offer my cultures. One jar in particular is literally top-tier. It’s my culture that holds both black worms and Daphnia together. Forget the bad reviews and test it out. Just because the eggs don’t hatch doesn’t mean the culture that you have alive won’t reproduce successfully in months to come. They need to get acclimated to your water perimeters and environment you put them in. I now have seed shrimp, copepods, and Moina all thriving in the same jar. 🦀 Peak move is setting up a sponge filter with live floating plants and do not worry about the bubbles, pushing them around. They will be completely fine.

Unfortunately, nothing hatched. Not sure what I could have done wrong so I guess...bad batch? I figured after 2 weeks I would see something if there was anything. If I jumped the gun and something happens Ill update. Update: Guess I couldn't see them but after a couple months I now have millions of them. I guess I didnt know exactly what I was looking for... or they were just too small for at least a month. Would be 5star if both caps were able to produce but I guess I got enough out of the 1.

Don’t waste your money. I am a biology professor and hoped to hatch these Daphnia for my class. I set up an aquarium for them with air pump and everything. Ideal conditions. Not a single egg hatches from EITHER vial. Complete waste of money. Do yourself a favor and order a bag of life, hatched specimens from another seller.

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 🤭.

Add my name to the list of people who had zero luck getting anything except two worms to hatch from these eggs. No luck in a tank that once had a thriving population of daphnia in it (fed them all to my fish and wanted to reestablish a colony with the eggs). Also tried two other setups. Nothing. Monitored water conditions weekly (Master Kit). Tried different temperatures, aeration and no aeration, lighting and no lighting. Basically all I can do is feed the eggs to the fish and go back to buying live daphnia locally.
