Do you ever get up to Massachusetts ??
There is a Barramundi Farm in Turner Falls I went to 2 years ago
They do not advertise regular tours But I stopped in on a Saturday and
chatted up a guy working there got a full tour of the place (Very cool place).
The filtration towers alone are worth going to see 6 of them about 3 stories tall and what looked like giant bio wheels about 4 feet in diameter and 6 feet long used to remove the poop before the water was pumped into the towers
They get big fast and will eat ANYTHING they can get their mouths around including your fingers. The guy at the farm showed me the big vacuums they use to size and separate the fish every two weeks because a 8 inch Barramundi will try to eat a 7 inch one and choke and die
The two I had out grew my 150 gallon tank in less than a year
Here is their info you never know they may give you a tour and give you a couple fingerling's like I got.
