Why did my goldfish try to escape?

your goldfish isn't trying to escape. gold fish retain a memory of approx. 3 seconds, the thought of flying like a unicorn excites them regularly and that just means you got one of a kind.

jkk, it probably and usually means that they just don't like you because your ugly and they don't like the sight of you. aka, they wanna die because you're so ugly.

jkk again. fo real now, a gold fish never tries to escape. some goldfish tanks may be too hot, or too cold to fit the homeostasis. to help re adjust the fishes normal body temperature, they use the air to cool down or heat up. try adjusting the light near the fish or if their near a heater or someth.
