What is a coculture:

Being daphnia are a filter feeder, organic matter not on a microscopic scale, is unavailable to them. That organic matter can pervert your cycle/biome and cause a crash. Daphnia benefit from a culture partner that consumes(processes) that organic matter. Most people that culture daphnia/moina do so with snails, but other things are just as effective, such as scuds, dero, etc. They aid the daphnia by ripping apart solid organic matter - releasing nutrients into the water for the daphnia to consume, and their excrament is rich in bacteria which is another daphnia food.


Auction:

75 Russian red daphnia & 25 scuds, from a co-culture kept in the garage, unheated, and kept under fluorescent light.

FYI: A common concern about scuds is they eat aquarium plants. That isn't accurate. Plants are something you want to keep with scuds. I keep several plant varieties in my scud cultures. Scuds are a detritus feeder. If a culture is very hugry they do nibble on the plants, but in a fish tank there is nothing to worry about.


There are no special tricks with a coculture. Add a slice of cucumber, the scuds will rip through it releasing nutrients for the daphnia, and their excrement is rich in bacteria - both great sources of daphnia/moina food. Scuds are my favorite to coculture with daphnia/moina. They are just as effective as snails but I use them as a food source much more.


Keep some of what I send as a backup:

Scuds are very hardy and little needs to be said about them - they are as easy as easy gets, however, daphnia are well known for being sensitive. If you remove most of the daphnia, and all the scuds, you can keep the water/culture I send as a daphnia/moina mini-culture for an extended time. Culturing in something as small as a soda bottle is as easy as something much larger - its just smaller proportions. Being I send a large amount of culture water keep most of it as your backup. Then, if your cultures fail to start, you still have what I sent you for a starter of moina/daphnia.

When you recieve the bottle gently pour it into a more usable container(a glass jar with wide lid works great), fill a couple tiny cups with the culture water, net out most the daphnia/moina and all the scuds, place into the cups, and then transition to their awaiting tanks. The culture water that is left over, about 1.5-liters, along with a dozen moina/daphnia, is then placed under fluorescent light at 6500 Kelvin(daylight spectrum). It will grow quickly. Then, if your primary cultures fail to start, you still have your mini culture to pick daphnia/moina starts from.

I fed it prior to shipping so it will be happy for two weeks. If you need to keep the culture going longer add a few drops of aquarium mulm, or add aquarium water(a great source of flora & fauna) every couple of days.


How to start a culture:

Scuds are very easy to get started but daphnia can be a bit a bit tricky. To ensure a successful startup with daphnia I recommend you start a couple small cultures. Yes, get your large primary culture ready, but for best results, start a number of small cultures. Culturing daphnia/moina in small containers just as easily as something large so start several. My favorite container to start daphnia cultures are 1-gallon milk jugs with the top cut off. Start each with water from different sources(aquariums), place in different locations both in & outdoor, and feed each differently. If your primary doesn't take one of the mini-cultures should.

The key to a successful startup is raising the level of organic matter. Daphnia like an organic rich enviroment. The more organic matter, with the addition of light, generates the growth of naturally occuring flora & fauna that aid in feeding your daphnia, and aids in keeping a balanced biome/cycle. To build up organic matter in a new culture use mulm from a fish tank. What is mulm? It's the debris you vacuum from the bottom of a fish tank. A fish tank with fish, snails, plants, etc, will provide a well rounded organic rich mulm. Fruits & vegetables are also helpful, such as cucumber, banana peel, melon, grapes, etc.

Week 1:
Any container works from soda bottles to pond liners. Lets assume 10 gallon for proportions.
Place under flourescent light(6,500 Kelvin) or where it receives filtered sunlight.
Add water. Aquarium water is ideal. If using tap water allow an extra week or two for cycling.
Lightly coat the bottom with aquarium mulm(3 to 6 shot glasses).
Add 1/4 slice of fresh banana peel & thin slice of cucumber.
Gravel, driftwood, aeration, are helpful but not required. A water only culture works fine.

Week 2:
Add 1 to 3 shot glasses of aquarium mulm.
Add 1/8 slice of banana peel & very thin slice of cucumber.

Week 3 - 4:
A few days before adding daphnia add a shot glass of aquarium mulm.
Add 2 to 3 daphnia per gallon. Don't add more as that stresses the cycling biome.

Feeding:
Outdoor: So much debris naturally falls into a culture there is little need to feed it. For a boost I throw in a banana peel each month.
Indoor: Each week I add a slice of cucumber/grape/tomato/etc, and every couple weeks a 1/4 slice of banana peel.

One of the most common questions I receive is why I prefer using banana peel & cucumber over something like yeast? I like them because they release some of their nutrients directly into the water for an instant feeding, and as they decay bacteria is released for the daphnia to consume. A banana peel will decay slowly over several months - acting like a time release food capsule. When some people make feeding daphnia sound like a science keep in mind green water isn't all that different than a cucumber slice.

Maintenance:
There is little need to clean or change water as the gradual buildup of organic matter is beneficial - that decaying matter encourages the growth of flora & fauna. Nitrates are kept at bay because the biome also grows. I lightly vacuum the bottom of a culture every month or two, and water changes usually come from replacing water I've dipped out when harvesting. Replace culture water with aquarium water.

Scuds:
If I were to select only one aquatic culture to keep it would be scuds. They are impossible to kill and always productive. They are larger and meatier than daphnia. I can release enough scuds into my aquariums to feed them for weeks at a time. The only tips I have is feed them soft fruits & vegetables, and give surfaces to cling to, such as plants(especially duck weed), driftwood, etc.


GUARANTEE:

If DOA I will send a replacement at no cost. Please don't file any claim as that usually adds additional steps for us both - just let me know and I will send another without a guilt trip.

FYI: During shipping, distance isn't a risk factor, neither is temperature - what will kill the culture is sunlight. It's critical the box not be left in your mailbox or sitting at your door. Alert your mail carrier you have a perishable package coming and ask for them to deliver it to your door. Watch for the mail carrier as it may still be placed in the mailbox. I will send a tracking number so you know when to expect it.
