These pods have been increasing in numbers in my tank, the adults are about 1mm long. They swim in swarms when I turn the pump off.
I am guessing they are a type of calanoid but don't have a microscope, these are the best photos I could get with my mobile.
They have hitchhiked in and seem to be doing well, I haven't bred any fish before but I was thinking the nauplii of these might
be good first food.
Any thoughts on what these are?
