RE: Intro/laser hype question

[Charter <charter@charter-terminal.com>]

My coworkers speculate that the end result of laser light show
exposure in young platies will probably be extra-jaded fish.  ("Oh yeah,
that action diving dog is okay, I guess, but lemme tell you about where I
grew up - we had laser light shows all the time!")

Sorry for the discussion duplication, though - thanks for bringing me up
to speed!
