If you got about 20 babies, the odds of getting a male is in your favor.
But hopefully you babies will grow fast enough so that your current females wont become grandma. :-D

The babyshrimps are now 38 days old. Last count said 22 babyshrimps :). The ovaries has been visible for the last couple of days. It looks like 6-7 of them are male the rest are female. I suspect the shrimp on the second picture to be a male.

Today i found out that they are sexually mature in 46 days.
Three of the young females are carrying eggs :)
They are 16-17 millimeters long.

Hi Bochr, glad to see your baby shrimp are doing well and already producing! The 37-day old baby/teenager pic is so cute. :D

If anyone was still interested in knowing if a female can carry eggs without a male, I can confirm this, though it is a different species, some kind of Palaemon, Palaemonetes, possibly Macrobrachium M. Lanchesteri? Anyway, I have two females and they have had eggs on their swimmerettes 3 times already. They drop it within a week.

At first I thought they were fertilized, thinking they could have held a sperm packet received while having been at the LFS (I think I remember hearing some type of squids was it? can hold onto and use sperm packets later). But because they never developed into viable eggs, I later concluded they were not fertilized. I was surprised at the subsequent eggs at month 2 and month 3 after having been away from male presence so long. But the very last time they molted was the first time they did NOT have eggs. It'll be interesting to see if this trend continues.

GunmetalBlue >> Thanks for the info.

I'm going to explode in shrimps soon.
Today at least six of the females are carrying eggs.
This is so cool :)
