As you know, when it comes to "minnows", creek chubs and fall fish have have quite large mouths. So they can and will compete for food with larger sunfish and bass in your pond.
Yes they do. The closest cabella's to me put some in there fish tank thinking that the bass would munch them down, but they didnt, and now those chubs pound the minnows the hardest during feeding time.
Here we have "Lake Chubs," very similar, they are border line invasive. They do work better for bait than shiners, but are soft fleshed and dont stay on the hook as well, and once the are frozen and unthawed, they really dont stay on a hook. but the fish love um!! it does not take much running water for these to reproduce either, and they travel up stream as bad as bull head and greenies.
I do wonder how similar lake chubs are from creek chubs. They call "lake chubs" an endagered species here ( a real joke ) and wont poison out a good trout lake with a horible wormouth population becuase of them.
