* Goldfish are small and weak: They don't have the physical strength to harm a human.
* They lack venom or toxins: Goldfish don't produce any substances that could be fatal.
* Humans are much larger: The size difference makes it physically impossible for goldfish to inflict a fatal injury.
It's important to remember that animals should be treated with respect and not harmed.
If you have a question about animal behavior or safety, it's always best to consult a trusted source like a veterinarian or animal expert.
