Apparently a Danish TV reporter missed that point - and has been convicted of animal cruelty for killing a dozen fish with shampoo.
A court says Lisbeth Koelster poured dandruff shampoo into a fish tank for a 2004 TV program.
The report was supposed to show that some hair products contain toxic chemicals.
What it ended up showing is that guppies die when you put shampoo in their tank.
A veterinarian reported the reporter to police two days after the show aired.
But the case wasn't heard until last week.
Though convicted, the reporter wasn't fined, because the court said her rights to a speedy trial had been violated.
