sometime in late September I noticed one of my amano shrimp was preparing to drop her eggs. The fry require a saltwater transfer if they’re going to survive. In the wild, they’re released in stream grow up in the ocean and return to freshwater. I was trying to prepare a saltwater transfer to mimic this, but by the time I was ready momma had dropped and I accepted this would be a project after my semester is over. Come October, I see a small fry snacking on a dead leaf (similar to size seen in pic two) and figured it would be a snack for the fish, not expecting it to survive without saltwater.
Can someone please explain why tonight, middle of December, I am now seeing who I can only assume to see that once small baby now a juvenile snacking besides its father (seen first pic), alongside another of similar size (third and fourth photo) , in addition to another small fry (second photo).
I am certain these are amano shrimp, both mom and dad are in the last photo (mom on the left dad on right), and there is no possible way any salt water could be in this tank.
I have two adult females, the one in the last photo is again carrying eggs and from what I can tell, she’s ready to let loose. Any insight into how this happened would be so appreciated

That happens sometimes. Nobody knows why, how and how often. Maybe it´s more common, then we know but most of them get eaten. Somehow some larvae survive in freshwater. Maybe a mutation.
I´ve read, that they are mostly sterile, but I can´t say, if it´s true. I would try to catch the next batch off larvae and try to raise them in freshwater. A little breederwork. Maybe you can get enough, to create a new “only freshwater Amano”
The female shrimp in the last is a wildtype neocaridina. Not sure about the presumed “male” (Eye distance a bit close for a neo IMO.) Likely you had already fertilized female neo in there that produced babies.
