Anyone know what this could be? It looks like some kind of shrimp and I see 4 of them in my tank. They are super small and I first noticed them months ago when I would turn off all my pumps and they would just be floating on the surface until I poked at them. I do have a cleaner shrimp in my tank but Iโm not sure if these could be the babies or something else. Hope itโs not a bunch of mantis shrimp.
