I would like to add this about the banded killifish and mummichogs. I have been fishing with these for years. I like the 3" size ones.
They can live all day on a hook. They can live forever in a 5 gal bucket if you feed them and change the water. They are well known around here as being the best bait for flounder.
I have personally fished these for catfish side by side against Danny Kings punch bait (which was the best) and the minnows won.
Besides catfish, they are excellent bait for LMB, Rockfish (striped bass), and chain pickerel. Smaller ones are great for crappies. They are also great bait for both yellow and white perch.
I believe the way both of these minnows act makes them much more survivable in a pond than say golden shiners and certainly fatheads. They are very fast and stay close to cover and dive into cover and hide when anything comes close. They can hide in just the leaves and detritus of the bottom. In a pond I'm sure they could survive the bass, if you stocked enough.
