I have Banded Killifish in our creek. They are beautiful fish!
They were by far the heaviest of any of the "minnow type" fish in our creek.
I was going to try them in a forage pond and see if they thrived. If so, then I was going to determine if they would also thrive/reproduce in a pond with predators.
(Unfortunately, we took a hit to the family budget on the pond plans.)
I didn't manage to weigh any, but I am pretty sure they had 5-8X the mass of my largest Gambusia for example.
