It's Native to Australia, check my gallery, they'll be under "Bazza", or "Gazza"
they grow up to 2 metres long in the wild, and weigh around 100 to 150 kg's..
mine are only 1/4 foot long..They are somewhat Brackish as they go to the mouth of the river to turn female and spawn at around a foot long, afterwards returning to the freshwater to live untill next spawn..
found in northern Australia, however, I'll be getting at least 1000gallon ponds to keep them in when they are of a decent size..they seem to adjust well to a cooler climate...(i'm in Mid Coastal Western Australia-ish)
