I bought these recently to begin growing in a 5 gallon nano tank. They arrived faster than expected (within 3 days) and in great condition. The box was small and lined with styrofoam to cushion the trip and the daphnia were placed in a small bowl that was well-sealed.
Within a few days I could tell a big difference in the daphnia population. It's been a little more than a week and their population has doubled. They mainly swim at the surface of the water because they attract to the tank lights but you can see many of the smaller ones swimming against the back-wall of the aquarium.
These are great to use as a treat for your fish. I was worried about the "magna" size but they are still perfect for any adult fish. I have 4 guppies and 4 black skirt tetras in a planted aquarium and they go crazy for them. To harvest/collect, I just use a scoop and place it at the surface of the water where they are attracted to the light and gently dip it into my fish aquarium to release them.
Algae takes no time to form in the aquarium. I was worried so I put several decaying plants I removed from my other tank. Don't worry about feeding them anything additional or you may cause a rise in nitrates/nitrites. When doing water changes, try to have the lights on top and pull water from the bottom to avoid removing some of your population.

Alive and Well
1st: Don't complain about getting them in green water. That's the environment daphnia live in.2nd: They arrived alive and kicking.3rd:These might be the biggest kind of micro-species. They didn't work for my original needs, but my danios now have a very expensive snack.4th:I received some extra "material" in the bag. I'm not sure what it is, but looks like algae with larvae eggs. (Not excited about that) You should always quarantine your new aquarium stock. Only time will tell what the extra organisms are.All-in-all, good product.

I received a bag filled with murky green water. The only thing which you could see right away where the mosquito larva, which I guess you could see as a plus but it also had me wondering if they just filled up a bag with pond water. After I tried to dilute the green water, and remove some of the debris I did find some daphnia. However, there was definitely no where near 500+ "live" daphnia in the bag. The concentration of "live" daphnia I saw matched none of the pictures I saw in the reviews. I think I received more dead insect debris than actual daphnia.
I posted pictures of water that came in the bag. I also posted pictures of some of the insect debris I separated from the water. In the other picture, I placed the water in a white bowl and added water I stored for my fish tank. What you see there is mostly is debris from dead insect that came out of the bag and hardly any "live" daphnia. Unfortunately I didn't take pictures of the mosquito larva. I plucked them out of the water with tweezers and got rid of them quick.
I contacted them for a refund and heard nothing back.

They arrived alive and well. There may have been 10-30 that didn’t make it. There were a fair amount of shedding in the bag. By the second day there were even more in the tank. Lots of babies. The last pic is of Colonel Mustard and he loves these things. I think that’s why he is so beautiful. I will be ordering again.
Received my second order and everything was great again.
Thank you
Update: my culture is thriving. My fish can’t eat them as fast as they are reproducing. I’m so excited how well they are doing. I’ve tried cultures before with a little success but this must be a strong and healthy culture they have to offer. Just wanted to give an update that they are going strong.
