Shrimp Eggs?
I've just noticed one of my Amano Shrimp was an unusual colour underneath, upon closer inspection it has lots of little balls which I can only assume are eggs? It took my a while but I eventually got a photo.

So what do I need to do now?
How long before she drops them?
Will they hatch in freshwater?
Will the snails eat them?

Thanks for the help!

I have no personal experience with amanos but I do have RCS.

Here's some information I found from Amano Shrimp | The Shrimp Farm

"The Amano Shrimp is one of the more difficult shrimp to successfully breed in the home aquarium. The young shrimp do not hatch as small versions of the adults, like a Red Cherry Shrimp does, but they hatch as larva. These larva require salt water to grow to metamorphosis and become freshwater shrimp again."

And they have a 30 day gestation period like mose dwarf shrimp.

In these 30 days I would recommend to refrain stressing the pregant females because if stressed she will just release her clutch and most likely they will die. When doing water changes I would stay away from her. Also I wouldn't be doing too much gravel cleaning since this is where most babies seek cover. They will be so small you will suck them up without knowing.

I know people on here have amanos so they should be able to give you more advice as far as adding salt..etc.

Hope this helps!

I did quite a bit of research on breeding amanos..

You will need to set up a small saltwater tank, plus a saltwater jar with some liquid fertiliser added.

The jar will eventually be full of green water, which you can feed to the larvae. You can add some crushed green leafy vegetable to the jar to (supposedly) speed up the process.

Here's by far the best source I've found-
