Me not from Australia. Just thought of bumping in with some input on meds you might need on hand just in case.
Like all wild caught specimen, it is always advisable to de-worm that particular fish. Something that would treat for both internal and external parasites and worms.
You should be looking into Prazi Gold or Prazi Pro.
Personally, I QT all new purchases and treat them as per dose.
Prazi will be added into main tank for about every 2 months for a few more cycles (as a preventive measure).
What is the Datnoid scene like down under?
