For the last few nights I have been expecting the eggs to hatch.
They are very plump now, with the swimmerets now no longer able to close neatly. The underside of the shrimp looks disheveled.

Excelent view of the limbs which allows a description.Zoea 1,the first stage,has two pairs of limbs called maxilipedia (MP2 and MP3).But each splits in two "legs"called endo and exopods.Looking as if there are 4 pairs instead of 2.In this pic one can easily see how endop and exop stem from the same root. So we have from the front to the rear: MP2 end.-The short one. MP2 exop- MP3 end.-(coloured point) MP3 exop. endop of the right MP3 is bent to the left side of the larva. And we also have a clear view of the antennula (A1) and antenna (A2)

New hatch tonight of about 100 fry.
This will be the last hatch until I get some more brood stock. My largest shrimp has now killed two other cleaners one at a time over (I think its the large one doing the deed).
There are some other shrimp in the same tank. This pair has been together since may last year.

well my estimate of 100 fry was way off.
tonight in cleaning out the black bucket they are in I stopped counting at 250.
So either they are able to self duplicate or I cant count.

I'm finding raising these little aliens really exciting. Every time I take photos of them, they are different. Its like a little surprise every couple of days. They are 6 DPH as of tonight and seem to be going strong. Even though Im not getting any through as yet, with these or the peppermints, its still fun and I appear to be making progress slowly.

Again your pics are outstanding!
You focused on the antennae and we can see a flagellum between A1 and A2 which shows only briefly,in Z2.Amazing!

Thanks Luis,
I need to learn more terminology ...
In the second shot there are what I assumed are gills that are external to the body as the were pulsing as the shrimp was sitting still.
These have a red base with white fluffy ends that pulse, like a breathing action.
Each of the photos are of different shrimp fry. The middle one was "bulkier" than the other two to the eye, it's what made me pick that one, it also looked red in the body. The other two were lighter and pail yellow to white to the eye.
Under the camera this red colourful was not apparent, I checked a number of fry with the same result.

No,these are maxillipedia,not gills.Anatomy of larval appendix is a little complicated.See my threads for a description.Yes,they keep them moving like bringing water to their mouths. This is the 2nd zoea and only during this stage,we can see this flagellum between A1 and A2.Hard to see and a nice photographic document!

well its another big bucket of fail.
They are all dead again.
I keep making stupid choices with these guys and the peppermints, like "that bucket looks a bit dirty, its late so Ill clean it tomorrow". Then I forget to clean it the following night and then they are all dead. Grrrrrr.
Its my own fault, if I cleaned it straight away, it would be fine.
