These fish are super aggressive and nip and tatter the fins of small native fish, like gudgeons, and tadpoles. They are one of the most invasive species on the planet thanks to people thinking they control mosquitos and moving them all over the place. Their ability to have 50-100 live young every 4-6 weeks and the young being ready to breed in 8 weeks means they can rapidly dominate a waterway in warmer weather.

That's good to know @Walker
I hope birds and the Rakali I have seen previously in this little creek return to eat them. I don't think there'll be any Perch or Cod released up here.

Our native fish , Goldern Perch & Murray Cod feed on these species , the key to this is having a strong fingerling release to keep invasive species in check.
