Question from Keith Cheng.  Please respond directly to him

Dear Colleagues, 

Have any of you determined the level of chlorine that is toxic
specifically to zebrafish?  Post's Fish Health reports avoidance
behavior at 0.001 mg/liter, and the requirement in general to avoid
exposure of fish to 0.030 mg/liter for more than 1/2 hour per day.  Due
to expected variation of tolerance with different species and specific
conditions, we wanted to know about zebrafish.
