Which LFS still selling live daphnia aka boon??

[tetrakid]

hehe this thread has diverted lots... maybe should change the title..

Discussion about green water is important for those interested in Daphnia/boon.

Many Thanks to fireblade's green water. XD It's super rich and concentrated green water and my daphnia really like them a lot~

I've split 1/2 of the green water into 4 culture. 1x indoor culture with airline. 3x outdoor - 1 with fert and other w/o. All culture using my 1 week old tank water with super high NO2 & NO3 levels except one with tap water. XD So far the one with fert doing the best. Next will see if the fert green water will harm the daphnia or not.

@Shifu UA & tetrakid,
I think I am ready to give you guys some daphnia, you guys still interested? I just started my 2g tank culture last wed and so far doing quite well, population of hundreds. I have another mini tank almost overcrowded soon.

Wow, happy to hear that your Daphnia are breeding well, Bern...
Keep on going.

^_^ Thank You... XD Thinking of getting Russian Red... but I think better focus on pulex 1st and find the most effective way to culture them.

Russian Reds will be more demanding. Either airconned premises or some form of chiller may be required.
All in all not worth the investment outlay.

Maybe I will try a small culture?? XD But not so soon.. my focus still on my pulex.

That's the spirit, man. Like.
It's no harm actually, to gain first hand experience. I fully support you.

Thanks for the encouragement. ^_^ Hopefully able to find a good source of RR.


Here's my update on new 2g tank:

Very good. You can source around for some RR or Magna resting eggs.

I suggest you only concentrate on the arts of Daphnia culturing. Forget about keeping any fish for the time being. except for those in the green water culturing tank. You can feed the excess Daphnia to them to keep them thriving (for the sake of the green water algae).
Acquire the expertise and you will have valuable knowledge and profitable know-how in time to come.

Very interesting article. ^_^ Thanks for the source. Last time I was thinking of using the water used to wash the rice and they seem rich and milky.
As what I suspected, Adult Daphnia is bottom feeder too. I saw them a few time diving down and up seem like feeding on the detritus.

Currently I using fireblade green water to start my cultures. I think using this way will be better in controlling contamination though it's slower. Also might be cheaper if culturing them outdoor. Cos I am afraid in long run, the fish tank method will be contaminated with the pesky Ostracod. >< I hate them a lot.
XD I haven't test my fertilized green water culture on my daphnia yet. Cos my fert contain 0.005% Zn and Cu. Hope it's not high enough to harm the Culture. So far the ferted green water has the best result but still not as green as fireblade's culture. His is really green... like wheatgrass juice. ^_^ Wonder how's fireblade Daphnia culture doing now.

I mentioned before to feed the green algae tank's fish with Tubifex. Dried food somehow will is not good for growing green algae. It may be the quality of the fish poop.

Poop of fish fed with live Tubifex may be the secret. Supplement the Tubifex feeding with your spare Daphnia. In this way, you don;t waste your Daphnia and enables you to continue experimenting. You can also experiment with a Daphnia-only diet for the fish by eliminating the Tubifex later. The problem with Tubifex is the additional expense and trouble. The fish is there to provide nutrients to keep your green water algae going strong. Without constant nutrients, your green algae culture will perish and crash soon.

Oh~ Daphnia diet only will be a good idea as I know that it's not contaminated. I think the setup gotta very simple without substrate XD I hate seeing ostracod and copepod popping out here and there..

Ya, it's possible to feed with your spare Daphnia if you have enough during the early stage.
What fish are you going to use for your green water culture tank? Must have fish, if no fish, then no green water (because no nutrients).
Whampoe market has a small LFS which sells packets of feeder fish.

For now, I no spare tank... can't use fishy method. My culture should be enough for daily feed of maybe 6 guppies. But.... no tank XD

=X Maybe can try using a bucket then put outdoor..

Bucket also can be used, but will be hard to see the water colour.
Ya, must be put outside for sufficient sunlight. Using a packet of guppies is excellent too.
More guppies is better, say 20x guppies for more nutrients for more green water algae.
If not enough nutrients, algae will be thin. What you need is thick pea soup or like fresh wheatgrass juice.
When your Daphnia culture becomes very dense, more will be needed.

But can't have filter or airline XD need to ecosystem. @_@ I will look into it and see what I can do... ^_^ Many thanks for your suggestions.

Culturing Daphnia is a dedicated undertaking. That's why I said must forget about keeping fish for the time being and concentrate all efforts on Daphnia.
But in the end it will be worth all the trouble when your system is developed.

The green water tank with guppies in it doesn't need any airline. It is self regulating low-tech system because the eugenia algae is a living plant itself. The developed bacteria in the walls and bottom etc will take care of the ammonia caused by the fish. Oygenation will be very good in good light, while the fish provides CO2 for the algae to thrive.

OIC~ Good to hear that.

XD So far I have been concentrating on my Daphnia more than my shrimps and fishes. Actually my shrimps & fishes don't require much of attention, I just feed them daily & weekly or fortnightly WC.
@_@ Still got many daphnia experiments need to be carry out...
