Thanks everyone for your responses so far. Please see my edit. I really want to keep my frog population. We love all the frogs on this place. More thoughts:
- channel catfish
If I stock them alone will they eventually eat all the minnows?
- small goldfish
This would make the family happy. Would they coexist with the fatheads, or would one outcompete the other?
- common carp
Everywhere I read about common carp there is a warning that they should be avoided like the plague. I want to know more about this. If they are stocked by themselves in a pond that's already muddy, would they harm anything? I love to catch and eat them like most of the world outside the US. I am wondering how much information I read about them in ponds is influenced by our cultural disgust for them.
Love to hear your thoughts. Thanks again.
