  • How do they breed?

  • @her209 depends, sometimes asexual but there are male and female ones... google them

  • @echosaisis agreed, google them!

    Basically, they normally breed parthenogenetically (asexual female reproduction). Under stressful circumstances (after drying out, etc.) equal numbers of males and females are produced, which in turn sexually reproduce. After sexual reproduction, the female leaves cysts (hard-cased-eggs) on the substrate, which can withstand dry-out until the temporary pool is filled again.

  • @Aquaticopia I wasn't the one who needed to google them

  • @Aquaticopia Asexual reproduction does not yield any male daphnia. It produces many clones of the female, who are all female as well.

  • can you feed them piss?

  • @echosaisis doh! sorry I meant that I agree with you that others should google them, not that you should. You look like you know what you're doin' there! I will need some advice soon haha..

  • @Aquaticopia Good place to read MORE than you'd want to know:

  • @YuckyLuckyDucky the bridgesii supposedly produces infusoria, which I guess Echosaisis is using to feed them. I'm sure some water changes will give them enough calcium from the tap, who knows. I wonder what else he uses for their diet. I just found a few dozen in my 5 gallon "nasty water" jug that I use to breed ostracods - now I'm trying to figure the most practical way to breed them separately without competition. My texas cichlid fry sure did like the appetizer!

  • Snails do not go with daphnias. Reason being is because snails and daphnias both need calcium and possibly other macro and micro minerals for all we know. So if you have snails in with daphnias, you will have daphnias competing with the snail for minerals which is a no-no if you are purposely trying to culture lots of daphnia for your aquarium.

  • im ordering sum today :]
