The batch I received had more triops and fairy shrimp eggs then daphnia eggs. Triops are a type of shrimp that look similar to a horseshoe crab, and will eat the newly-hatched daphnia if not removed promptly after they hatch. my batch had triops hatching out in less than 20 hours, and daphnia didn't start hatching until after about 32 hours. to distinguish between them, daphnia move in a series of "jerks" which gave them the common name of water fleas, while triops and fairy shrimp have a continuous, smooth motion. also, the triops have a large number of legs, while daphnia only have a couple visible. If you don't immediately remove / separate them, in a few days you'll have a few large and growing triops and nothing else.Also, the description is inaccurate as my order was packed in a plastic envelope - there was no growing container as show in the pic and listed in the description. It's a minor matter, as a container is easy to find.bottom line, if you want something you can store for a while and quickly start up a culture, this can work well with a little attention to detail and knowledge of what a newly hatched daphnia looks like vs a newly hatched triops. if you've never seen either, and haven't kept daphnia before, I'd recommend getting a live daphnia / moina culture instead. You can stimulate your daphnia culture to lay resting eggs and create a egg mix yourself for storage without the triops if you don't want / need to maintain a continuous daphnia culture. google Kai Schumann daphnia faq for more info on keeping a daphnia culture from the perspective of an aquarium hobbyist. for live cultures, google florida aqua farms and lfscultures.If you main interest is live food for aquarium fish and fry, lfs cultures has many other types of live food cultures as well.First off, I did read the description and the other reviews about the eggs for non-daphnia invertebrates in the package. Daphnia have distinctive looking eggs, I figured I could just sort them out and then hatch the rest separately. Unfortunately, there were only three egg cases in the package, two of which hatched. I hoped I had just missed some and hatched the rest of the batch, removing critters as they hatched, but I never saw any daphnia in the main hatch :(This pack came with a lot of critters the triops were the first to popup and grew quite quickly. I removed the triops as I found them and for a while I thought I had done something wrong because that's all I got. Then suddenly I noticed fairy shrimp and started raising them. Its probably important to note that I didn't have the proper type of algae as the only type I had in abundance was the kind that grew in clumps on the glass. I also supplemented with a little yeast. All the while I noticed some daphnia, but just one or two hidden away and then all of a sudden I had a huge population bloom and the whole aquarium was full of daphnia. I started to play around with the amount of yeast I was feeding them to get increasingly denser populations, until finally I over did it and wiped out the culture. I would do it again. Especially since my aquarium has had time to mature and I'm starting to get fish that are spawning and an abundant supply of small fresh water food source would be useful.Daphnia? Sure. But this mix proved more interesting than just a daphnia starter culture. I had triops hatching out in less than 18 hours, and quite a few of them. The triops came and went pretty quickly, then the daphnia population exploded. I had hundreds of daphnia swimming around for a couple of weeks, then they died down to smaller numbers. About the time I was going to dry out the debris in the tank and start again, I noticed a female fairy shrimp moving around, so I left the tank alone. The daphnia population surged again and the fairy shrimp got quite large. The fairy shrimp developed an egg sack and laid its eggs shortly before it died. Another female fairy shrimp appeared, eventually depositing its eggs and dying as well. The daphnia have been a constant, their population going up and down...I'll eventually get around to drying everything out and restarting, but it's still fun to watch the activity after 2-3 months.I ordered twice from this company and both batches did well. They all hatched nicely. Just need to follow the instruction to remove all the triops. I got plenty of daphnia both times to start my culture. The first time failed at week 4, when the nitrite level was too high and killed all daphnia. The 2nd time I only used half of what is in the package and it still goes well so far after 6 weeks. I monitor the nitrite level twice a week and did 2/3 water change weekly. I can collected quite a few daphnia from my 5-gallon tank twice a week for my goldfish as snack. Here is a link to a great web page on how to culture daphnia: [...]The pictures are from last week.Overall, the quality of the eggs is good and consistent. Removing the triops is a bit annoying but not unbearable at all.These kits make sense if you want to start a daphnia culture which can eventually be used to feed live daphnia to your fish.I regularly hatch baby brine shrimp for my fancy guppies and they really enjoy it, so I decided to try doing the same with daphnia.Thus far, the eggs have been sitting in tank water for several days and only a few tiny daphnia have hatched. The rest of the eggsremain unhatched. I have a second packet that I purchased which I will try if these eggs don't hatch.However, if these eggs fail to hatch I will try another company.These packets are not inexpensive, and thus far the money has been wasted.I will update my experience with the second packet.I got about 5 daphnia out of it -- but that's great for my purposes! I'm raising triops. So I didn't have a problem with getting more triops and fairy shrimp. I'll buy it again but I do hope future packs have a better ratio -- I do have to feed all those triops!
