Industry and Investment NSW Aquatic Biosecurity and Risk Management acting manager Melissa Walker said pearl cichlids or pearl eartheaters (Geophagus braziliensis), were reported in Murwillumbah and Uki in late 2008.
“In recent months we’ve received new reports of the pest fish being spotted near Dum Dum on the Tweed River and again at Doon Doon Creek, below Clarrie Hall Dam, on a tributary of the Tweed River.”
Ms Walker said there were concerns about the impacts the pearl cichlid would have if it became more widespread in the river system.
“If you catch one while fishing, the best thing is to take a photo, freeze (the fish), and record exactly where you caught it, then call to let us know,” Ms Walker said.
The species, which is a native of South America, is a popular aquarium fish, with a pattern of pearly spots over a grey-green body with red-edged fins.
When breeding, a pair cleans a nesting site and guards the eggs, and may be very aggressive to other fish which enter their territory.

This is the type of behaviour that spoils our pass time for all, if you no longer whic to keep a fish, give it to someone else or at the very least a local pet shop or zoo etc.
