Pregnant Cherry Shrimp...??

[BettaFishGirl]

I've noticed a change of behavior in my cherries recently. They are in a 10g heavily planted tank, with some tetras. For a few days a barely saw them, and now they are crazy. All over the tank, usually on the wood or glass surfing. I've noticed a few look bigger (see pics) in the back end, but I don't see any eggs. Could they be getting pregnant (or gravid)?

Some of those look berried. Mine have gone through looking like that recently now I have a number of little ones, finally, swimming around. I will caution that there are some diseases and conditions that can cause the shrimp to get growths in their swimmerets but I don't see that in your photos. The zoomy behaviour you are seeing might be caused by a female shrimp with eggs in her saddle moulting, they release a hormone that makes the males seek them out so they can breed. FYI I am new to shrimp as well so I am only sharing my personal experience.

I had male amanos whizzing round their tank yesterday


Except for the most heavily coloured cherry shrimp it is usually possible to see the eggs under the female's abdomen and they could be yellow or sometimes green. I'm afraid I can't tell from the photos

I shined a flashlight kind of behind them and I didn't see any spots, but they could be hiding.
