Daphnia Magna

None of the eggs hatched and you cant get a refund

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.

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.

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.

Junk. Nothing hatched. Don’t waste your money.

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.

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 ends Original 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!

The ones that did bred like crazy!! I am now the proud owner of a large Daphnia colony! I’d definitely recommend since there aren’t any other daphnia eggs on sale here at Amazon. They get only three stars for low hatch rate though… Daphnia sexually mature in 8 days and then start breeding!

Hab diese wasserfloh Eier gekauft in der Hoffnung dadurch meine fische immer wieder mit Lebendfutter versorgen zu können. Leider wurde ich stark enttäuscht.schlupfrate ist sehr niedrig. Sowohl drinnen in einem seperaten Aquarium als auch im Garten in einer Regentonne. Da sind im Garten in den anderen Tonnen mehr wild gekommen als bei den Eiern. Und den Preis finde ich zu hoch Kann es nicht empfehlen zu kaufen

I regularly hatch daphnia from other suppliers. This brand has a 0 hatch rate even in a dechlorinated, heated tank. Amazon declined my refund or re-ship request, so a credit card chargeback will have to do.

Lots of terrible reviews but I've bought these several times over the years and never had an issue. First of all you need dechlorinated water I've used spring water, melted snow, even rainwater they all work. Next you need it to be fairly warm and they need some daylight. Next they need time. Sometimes they hatch in days and sometimes it takes a week or more. DON'T GIVE UP ON THEM TOO SOON!!! When they hatch they are so tiny so you will struggle to see them it is easy to assume it didn't work and dump the water down the drain. They will hatch. I have literally tossed them in a Home Depot bucket of rainwater and scooped them out all summer long with zero effort on my part beyond tossing in some spirulina powder here and there.

Not a single hatchling under highly controlled lab conditions.

I bought Daphnia Magna and had 0 results. Nothing hatched. Purchased Moina last year and had amazing hatches
