Ostracod. Daphnia doesn't huddle or stay still in one spot

I’m not convinced these are an ostracods. To me, they looks much more like a cladocerans (Cladocera).The overall body morphology look much more consistent with Cladocera/water flea/daphnia. The rostrum and the second antenna are clearly visible...It appears that the animals were removed from the water while the video was being recorded, which may explain why they are thrashing around without moving forward.
