I would venture a guess that it depends on the kind of fish and a person.  I 
vaguely remember reading a medical encyclopedia which mentioned that lethal 
dose of ehtyl alcohol is 450mL for an average person, except russians.
(BTW, I am russian, so it's OK to make this joke.)

Seriously, pumps not specified for use with potable water may leak something 
into the water, which might be present in low enough concentration to not be 
acutely poisonus, but have long-term effects.  Fish usually do not live as long 
as humans do and do not have as much medical attention.
