Anyone out there know about daphnia, or somewhere I could find out some good info?  I just got some off of Aquabid, and I'm not sure what to do with them yet. I'd really rather not kill them.??? :eek: ???

check out www.thekrib.com
or www.e-aquaria.com

the best food for daphnia is green water...
it really isn't necessary to purchase daphnia though... you can find it in most low current water bodies (ponds and such).  Just get a brine shrimp net do some figure 8 motions and you'll most likely get enough daphnia to start your own culture.

to make green water, you can get a 2 litre bottle (or several of them), fill them with tank water (not tap water), and leave it in the sun for 2 or so weeks.

but since you've got a culture already, i think some liquid fry food or dead yeast would have to do for now until the green water develops.  but use the fry food or dead yeast sparingly cuz too much can spoil the water and kill off your culture.

you can find more info at the links provided...

Err, actually, finding standing water around here is just about impossible.  I tried for 3 weeks to find some "free" ones, then I just broke down and bought.
I run a DIY CO2 rig for my plants. When you say "dead yeast", do you mean the white gunk at the bottom, or the liquid?
Thanks for the site info, by the way!

honestly, i've never tried the dead yeast method.. since i've yet to go and try to collect some daphnia..

i wouldn't put the "dead" yeast from your co2 bottle b/c its already contaminated with sugar...

i'm sure i read about the dead yeast thing from one of the two sites... but nevertheless, you'd be more safe with green water.

Thanks, Sega
I'm "growing" some greenwater right now, but it's not ready yet.  Guess I've gotta keep using the yeast.  Thanks for the info.  That's the trouble with these little suckers....there are several sites out there that promote their use but noone can say for sure how to raise 'em.  I guess it's all by guess and by gosh. :-/

dead yeast?..let active yeast sit out at room temp for a week or so. Test a small amount to see if it is active in warm water(does it foam?) If not, the yeast is dead.

Active yeast is "alive", and the reason it should be kept in the refrig (or freezer)after you open it.

Ryan, don't go calling yourself retarded.   Learning about new stuff is what these forums are all about.  I read about them on thekrib.com. There're all kinds of groovy little bugs you can feed yer fish.

Daphnia are also called water fleas. I don't know what all colors they come in, but the ones I've got are red. They swim with a herky-jerky motion, are really tiny (but still visable; about 1/16" at best), and fish suck 'em down as fast as they can get them.  Really good live food.

Eventually I'm going to try to get my fish to breed, and I'll need some live foods around for preping the parents for "the deed" and for their fry later on.  Thought I'd start learning how now rather than later. :)

Bettaman, are you sure you're not talking about infusoria?  I've heard that's the way to make it.  Can you actually see the little buggers?

actually the size of daphnia vary in size...  I've found a source (a pond in a japanese garden) about a month ago where the daphnia was still visible even when i'm looking a metre away from the surface.  Unfortuneatly, just last weekend when i went back with my water bottle, the daphnia population was pretty much eradicated.  

i guess i'll need to find a public source where i'm allowed to use a net.
