Not possible. The are regular dwarf shrimp in that aspect as the female carries the eggs in her carriage until they hatch.
I'm also wondering about the instant change but I'll cross that bridge on next round. Right now, the brack tank continues to do well.
Here's and odd thing. The zoea in the lower salt tank seemed to have perished as well. Very, very interesting. Maybe they were too old when I moved them and just didn't quite have the strength to carry on. I'll check it again this evening and see.
I will try this salt level once more with the new batch of zoea.
Plus note: Rotifers arrived today. Culture will be started either this evening or tomorrow.
That would be an option depending on how the brack tank turns out. The idea was to reproduce a tidal current which comes into the area and then sweeps things out to sea. Thus the immediate adding to the salt water conditions.
Now what I found very interesting was the latest test involving the low salt level. I'm anxious to get the next round of zoea and see what happens as that tank had perished too. But as mentioned, it could have been an age thing with them.
The brack tank keeps chugging along. {knocks on simulated wood}

And we're growing....
Don't have to strain the eyes so much to see them now. Going to try and clean up the bottom of the tank a little bit tomorrow and add some fresh water. While not necessary, I'm going to see how they react to it. Plus add a fresh coarse of phyto.
Over in the low salt tank, there is promise. I managed to locate (2) floaters. Definately makes me believe it was an age thing that lead to the others not making it.
I've decided that I'm also going to create a freshwater test just to ensure they actually need the salt to survive at this stage.

Reset both salt tanks. The brack tank wound up going sour. A couple of thoughts come to mind:
1) changing of the water as I did. May not have been a good thing. Need to find a better way to clear the bottom or just increase the circulation. Don't want to over do it as I'm pretty sure the zoea might be a bit on the fragile side at this age.
2) Temp. Which this one I am exploring more closely. Room temps seem to be in the mid 60s where they are located. The light really isn't bringing the temps up any. I'm looking for an alternate spot at the moment which would provide some additional heat for them.
3) Food source. The water stayed a nice green tint with the Nannochloropsis. I'm not sure how big the rotifers get if they would be too big for the larvae or not. I have the rotifers culturing just don't know as to how well the starter culture was as they were a "resting" culture.
One female hatched her zoea out last night and there is one in the tank that is hatching earlier than calculated. Found some zoea in the tank. She is now in isolation. Two more females are egg laden.

I wish I was a fish I wish.
I think I read that if the water is hard enough it is possible to raise them without salt. I lost all my links on breeding them.
Q
Just read through the whole thread, James. Looks like you're makin' excellent progress. The main hurdle is transitioning from brackish to full salt. Do you think it's possible that the additional osmotic pressure happens in too large a step? Can you take your existing brack tanks that they're doing well in and gradually raise the salinity to full salt? Then, rotate the tanks that you'd earlier dedicated to full salt to brack tanks for the next batch? Thanks for keeping this log going. Very instructional!
