If you pay prior to Monday morning your culture is almost certain to ship that week.
75 Russian red daphnia, from a culture kept under fluorescent light, and kept at a minimum temperature of 50 degrees in my garage. Shipped priority mail in a 2 liter soda bottle. These ship well year round.
FYI: You can keep what I send you as a functioning culture. Being I ship priority mail, without a weight restriction, I send 2 liters of culture water. I also feed it prior to shipment. If you retain most of the water it will support a dozen or two daphnia for several weeks - without needing to be fed. Simply net out most of the daphnia, place them in a small quantity of the water I send to transition to the new cultures, and keep the rest as a culture. If your cultures fail to take you can keep picking daphnia from mine until they do.
IMPORTANT CULTURING ASPECTS
There are hundreds of species of freshwater daphnia and few people truly know what species they have. Many strains, even when labeled with the same name, are likely significantly different. One daphnia may prefer hard water while another prefers softer water. For best results match up water chemistry and culturing method with the source. Below are details important for a successful startup.
Water: My water is middle of the road in hardness and pH.
Temperature: My cultures are kept in the garage, only heated in winter, at a minimum temperature of 50 degrees.
FYI: You will want to start at temperatures similar to the source culture - so you don't shock them when transitioning.
Lighting: Strong fluorescent for 12+ hours each day.
Feeding: I feed primarily boiled fish tank mulm, cucumber, green water, banana peel, and bugs.
HOW TO START A CULTURE
Daphnia, though easy to culture, are notorious for total crashes while transitioning to new water. Once you have them established in your water they are much more resilient. I highly recommend, in addition to your main culture, you start a few tiny cultures - each with water from a different source. If your primary doesn't take one of the small cultures should.
FYI: I find it easier to start a small culture than something large. When I obtain a new strain I start them in one gallon milk jugs with the top cut off. Use this to your advantage by starting off with as many cultures possible, each with water from a different source, and one of them should take. A milk jug supports a colony of several dozen daphnia.
Steps:
1) There are hundreds of species of freshwater daphnia/moina and few truly know what exact species they have. Not all daphnia are the same. For best results, start with a strain that is kept in similar water, and cultured using techniques you will use.
2) Create a large primary, but to ensure a successful start, create several small cultures using water from different aquariums. If your primary doesn't take one of the small cultures should. Culturing in anything over a few cups is just as easy as something larger. Gallon milk jugs with the top cut off work great.
3) Add a layer of natural gravel and a sponge filter. Aeration isn't required in a tiny culture, but I do recommend a sponge filter with your large primaries. Keep the bubbling to a minimum.
4) You can culture in water straight from an aquarium, some have tap-water good enough to use from the tap, but if you are starting with a new strain its best to start with a cycled tank. Why? Daphnia are very sensitive to nitrates and cycling establishes beneficial bacteria that will reduce nitrates - just like in an aquarium with fish. If you place daphnia in an uncycled culture, and start adding food, you are setting up a likely crash because the bacteria cannot keep pace. If you are using water & mulm from an aquarium cycling takes a week or two, and if using sterilized ingredients it takes four weeks.
FYI: Aquarium water from a healthy tank is the safest to use for culture water. However, ensure it doesn't contain hydra as they are culture killers. You can age tap water by filling a clear bucket, adding aquarium mulm, and placing that where it receives light.
5) The moment you create your culture, even though there are no daphnia in it, start feeding. This will help establish bacteria that will reduce nitrates and act as a food source. If you have a nicely cycled pre culture, and start it with a small number of daphnia, the natural bacteria(flora & fauna) alone will sustain them. For a 10 gallon culture lightly powder the bottom with mulm, add a banana peel the size of a business card, and a very thin slice of cucumber. The following weeks add smaller portions. Ultimately, you end up with decaying organic matter in various states of decay, and is rich in bacteria.
FYI: What is mulm? It's the organic debris that collects on the bottom of a tank and encourages the growth of bacteria - something bad in an aquarium but great in a daphnia culture. Mulm alone will feed a small population of daphnia.
FYI: There are many things you can feed to daphnia - most of it works. I like to feed natural type foods as the cultures are much more stable. When people start to make feeding daphnia sound like a science keep in mind a cucumber is just as effective.
6) Your culture is cycled after food has fully decayed and other additions are in various stages of decay. It's then ready for daphnia. For cultures under 10 gallons add half a dozen daphnia or one dozen moina. For larger cultures you only need a dozen or two.
FYI: The reason you start with a limited number of daphnia, in an indoor culture, is they are very sensitive to nitrates. Being daphnia can have multiple offspring daily they will quickly populate the culture - faster than the bacteria can keep up.
GUARANTEE:
If DOA I will send a replacement at no cost. If DOA message me and I will get another in the mail.
Distance isn't a factor in shipping - as they will be on a plane. The time a package is vulnerable is when its out for delivery to your home. If the package is exposed to the elements it's likely to perish. It's critical the box not be left in your mailbox. Have somebody home that is prepared to greet your mail carrier.
