Got this girl as a freebie from one of my LFS's...
when i got her, she was carrying eggs, looks like they've been released into the tank, but i have yet to see any babies, so this shrimp probably needs brackish to breed, whatever it is...
It's a........shrimp! Seriously, it's tough to tell without looking at the shrimp in person (and maybe at some dead shrimp or shed skin). This shrimp could be a Neocaridina denticulata of some sort (very variable) or one of the Indian shrimp varieties that are also very variable in coloration.
How large were the eggs...were there several hundred tiny ones or maybe around 30-40 larger ones? She either dropped her eggs or the young hatched and are either floating around or crawling around in your tank are are too tiny for you to see.
the eggs were tiny and dark brown, her coloration is a deep brown, i know she's not an Amano, that's for sure, the LFS said she was a "wood" shrimp, but i see no evidence of filter fans, looks like she has the same feeding leg setup as Amano and Cherry shrimp, she's about 1.5" long and i'd assume since she was carrying eggs, she was fully grown.
another possibility for the hatchlings is that they were eaten, i do have a Vampire shrimp in the tank
