Pregnant RCS molted eggs... help?

I've had several pregnant RCS in my 37 gal planted tank (74 degrees F, containing harlequin raspboras, pristella tetras and hillstream loaches).

Today I look at the tank and I see that one of my pregnant RCS has shed her skin... with the egg sac inside!

Does this mean that none of the eggs will hatch? Were they never fertilized to begin with? What happened?

I attempted to take a picture of what I saw. (Notice that there's a snail hanging off of the shed skin.)

I raise CRS and I can say I have no clue, I would think if they were fertilized they would/may hatch if something else doesn't eat them first. Seeing that she shed them I would also think there is something wrong with them I mean I guess it could be an accident but I would think maybe not. Again I actually have no facts to back me up only guessing, if I were you if you have a specimen container or something I would stick the eggs in it and see what happens.

I wouldn't worry about it.

Once the fertilization egg process happens they don't moult. Their energy and resources are used towards carrying the eggs. If it moulted and she was berried, most likely the eggs were unfertilized. She will do it again.

I've had this process happen too many times.

So their reproduction process is:

#1 the male/female mate. At this point she's not fertilized or not fertilized enough?

#2 The female lays the eggs in her sack and carries them for approx 30days and in this phase the male will fertilize the eggs again?

Hi,

I have beem keeping shrimps for some time and i don't think the eggs will sruvive. By right, they should molt properly and if not, it might really have to do with your water parameters, what are your ph gh and kh now?

And i don't advise keeping fishes with shrimps. Hugh risks.

You can see my shrimps i am rearing at Kelvin's Crustaceans Adventure
