Ten most invasive fish species

[Dave 54]

I was reading an article in the Practical fish keepers website about the ten most invasive fish species in the world and how they manage to do what they do.
Some of them you'd be familiar with in the wild but there is one that will give you a shock as pond keepers.

See link to PFK site :-

One fish not mentioned on this list is the koi Carp which are causing great damage in NewZeland and are classed as pest nearly all the Australian states apart fro two class them was pest too .
Bot the other fish we are all fmiliar with as wee probably all kept them over the years some of you still do infact.
I'm talking about the humble goldfish of course
