Oh, I missed the Life - Fish episode. Hoping to catch it again. Saw the ending with the Jawfish.
As for River Monsters episode of ATF, great to see Jeremy catch one. As for the premise of the show, whether the Goliath ATF is that aggressive...hmm. Im not convice that they would attack humans or jump out of the water to grab people. At least from my experience of raising a Vittatus ATF, they are great at hunting fish but not aggressive enough to attack anything big as or bigger than themselves. Mine was able to cohabitate with cichlids, catfish, eels..etc
As oppose to Piranha, they would attack big prey when they are hungry enough.
