Above is a link to a short video of tiny critters near my shrimp at feeding time. They move in a twitchy type of swim and sometimes appear to hop. I am looking to identify these things. Are they daphnia? Are they baby amphipods? Are they something else (good or bad)? I think I’ve seen them hopping on the surface of my acara tank also. I have never noticed anything going after them or eating them.
I do have several amphipod cultures in separate containers plus I have them in two of my tanks. I remove the ones in my shrimp tank with a baster each morning and take them down to my acara tank.
I apologize for the loud noisy background, it is my 7 month old puppy chewing on a bone. I didn’t realize how loud it would sound in the video.
Thanks for you help and opinions.
