Congrats to your son on a surprising catch... Rumour has it this is not as uncommon as people have long believed.. going back an repeating this catch will confirm this.
Paddles...LOL .......shall we release you back into the wild and see if you breed?? LOL Breeding is instict for all fish, if they have a partner and the right water conditions they WILL breed...survival of the fry is another issue altogether!!
Maroochy river will be quite interesting this summer!!
