Unbelievable but true. there is a fish named Arroyo. The Arroyo fish can pass for normal "tilapia," with the difference on its yellow jaw, silver abdomen, slimy texture and foul-smelling odor. Rey Rivera, a longtime resident of the fishing town of Hagonoy, Bulacan said the "Arroyo" is bane to fisherfolk "since it has wound up in rivers, creeks and fishponds, consuming bangus fingerling, shrimps and feasting on whatever may be eaten" after the 2009 typhoon "Ondoy".
