I still dont belive it, look around on the net, also one of the lakes is protected, cant remember witch it is tho, all cichlids here in aus are tank breed no matter what people say. you see pics on the net with these guys who have these large nets with millions of eletric yellows in them and so on, but yet they call them "wild caught" but yet these fish have never seen a rock in there life. Why would a shop pay so much money for a wild caught fish when they can sell the same one breed in a tank for much much less?
Ah your in Australia, no wonder you dont see many wild caught fish then, most of them are banned from being imported into your country, i was helping someone a while back who wanted to find some nice predatory oddballs and catfish and we found a list which contained about 100 species of fish and they were the only ones allowed into the country. I should imagine that virtually all the fish in the australian hobby are farm or captive bred.
Here in England we have virtually no restrictions on the fish we are allowed to import and own since they could not survive the winter if released, the only fish we are banned from having are coldwater ones. Because of this we get a huge range of fish to choose from of which a great number are wild caught, we get BIG predatory catfish, FW stingrays, predatory characins like wolf fish, payara and FW baracuda, bichirs and many more fish that you Australians would have to have smuggled into the country and pay thousands of dollars for (i know of a few people who have paid in excess of $1000 for fish like tiger shovel noses and redtailed catfish).
The lake that is now protected is lake victoria BTW.
