Habitat killers, meaning they destroy their habitat or environment?
I'm not sure I understand that either, but it's an interesting idea.


I understand how koi dig and muddy the pond. I am not sure how
goldfish and sunfish doi that. Our goldies would multiply fast, as
would sunfish. How do thoase species destroy habitats?

We've probably all seen ponds overfull of carp. I don't think they can be
described so much as "habitat killers" as "habitat modifiers". They make
the environment over to match what they like. Sort of like people...
