Michael, just want to make sure about the fish you kept, since the
common name pacu is confusing in this country (and in Brazil, too, but
more narrowly so). What genus were your fish? I remembered
incorrectly, btw. I looked up the food habits reports in Goulding's
book, and he says around 2% arthropods for the various pacus ("silver
dollars") not including tambiqui when they are in isolated flood plain
lakes. For tambiqui, he found fish and arthropods in 2 out of 127
specimens. He did not examine any juvenile fish, however, and maybe
they eat more animal material. If your fish were tambiqui, I'd say
they were almost certainly juvenile fish, unless you have really big
tanks!
