Last night I had hundred of tiny shrimp looking guys swimming in my tanks water they did not seem interested in settling on any surface and seemed attracted to light. The only things I have in my tank or a pistol shrimp hermit crabs and a cleaner shrimp. I am unaware if there are any Mysis shrimp running around I have not seen any.
Here one is under 60x best photo I could do.
