CichlidFish.com - Fish That Think.

Just saw this blurb from Discovery Channel in the latest AFI.  Seems that aquaculture scientists in Greece have discovered through experiment that carp raised in a constantly dark environment, which would normally cause stunting, grew to a more normal size when exposed to the music of Mozart for at least 30 minutes a day.  Fish also showed enhanced fatty acid levels in their livers.
