Carolina Daphnia Magna Culture – Large Water Fleas For Aquatic Studies | Ideal For Toxicity Testing & Physiology Research | Includes Mixed Life Stages

This is the second time buying these guys. The first time I dumped them all into my pea puffer tank, needless to say they made quick work of them. This time I have a separate tank, hoping to keep these guys reproducing for constant live food. But they are super fun to watch as they twitch through the water. All arrived alive and very active. Highly recommend these guys!

The delivery was prompt, and they arrived all alive, with babies.

An excellent seller. Received my culture that multiplies very quickly. Feeding them to freshwater fish.

All Daphnia arrived safe and sound and I got them the day before their expected arrival. I'm very happy with this purchase and look forward to shopping their store again in the future! <3

The media could not be loaded. They arrived extremely quickly, literally two days after I ordered them, they are very healthy and there was only 5-10ish dead out of somewhere around 40-50 including the babies. A loss of 5 is quite a bit lower than I expected. They're all currently chilling in my green water tank, been a full 24 hours and they are Thriving. Though the box could've used a heating/cooling pack, but the weather has been nice recently so that may be why. 15/10 would buy from them again again. 🌟

The media could not be loaded. Arrived well, good product.

For the price you definitely get little like around 30 ish adult daphnia full size so a bit pricey. But seems pretty good day one and i already have couple babies swimming around.I went with this seller cause review said 2 day shipping, and they were right was about 2 days. Packaging was good too.Planning on culturing and left in aged green water from my aquarium so they are eating that.Overall pretty good, i would order again from this seller, also daphnia are pretty fun to watch swim around.

These Daphnia cultures ship much faster than advertised, my first one arrived several days ahead of schedule.Unfortunately the first one happened to arrive on one of the hottest days we have had this summer with temps in the 90's F and even though it had been shipped well packaged with an ice pack, the culture must have gotten overheated and did not do well, many DOA and most died off over the next 24-48 hours despite careful acclimation to a new habitat. I contacted the seller through Amazon and they promptly got back to me and shipped a replacement culture, again with an ice pack. So far the replacement culture is doing great, with only one or two specimens having died off. I definitely would recommend purchasing from Carolina Biological Supply.
