Agree about the fishing programmes
Check out my posting on the HHFL thread pg 9 (26/06/09) re Pacu
Despite them being always referred to as a vegetarian fish - I can vouch that they are most certainly NOT
They will eat ANYTHING - so far they have not had any scrotums at my place - as far as I know

As for eating them, they are very good up to around 1kg - when they get bigger they get rather tough. Very good flesh - not too bony as they have a flat skeleton. Very good bbq'd or deep fried with a papaya salad.
