said, euthanised 100%.
I’m not sure how it goes in other countries but here in oz if the authorities found you had one of these fish in your home tank you would get a visit and they pour some kind of super concentrated bleach into your tank that wipes out every living organism right down th the bacteria, leaving it completely sterile. No second chance and it doesn’t matter what else you have it all gets blitzed.
That’s why I am so shocked they only got a tiny fine for their first offence when it’s taken so seriously .
I wonder how many times they have been successful befor they were caught.
