Here's why:
* Goldfish are highly sensitive to toxins: Their small size and delicate systems make them vulnerable to even small amounts of substances that are harmless to humans. Caffeine is a stimulant and can be toxic to fish.
* Caffeine can cause serious harm: Even small amounts of caffeine can disrupt a goldfish's nervous system, leading to increased heart rate, erratic swimming, and even death.
* It's cruel and unnecessary: There's no scientific or ethical justification for harming an animal in this way.
Instead of experimenting, focus on providing your goldfish with a healthy and comfortable environment.
If you're concerned about your goldfish's health, consult a veterinarian who specializes in fish. They can provide safe and effective care for your pet.
