4. Emo Fish Soirée

Who knew goldfish were goth at heart, swimming in shadows and dodging the sun for an emo fish soirée? That's right, these little waterborne wonders are just looking to paint it black: Studies have shown that goldfish, when given a choice, will consistently choose a darker environment over a bright one. This preference for dim surroundings serves as a defense mechanism against predators, like birds, and helps researchers develop models for studying anxiety in the species. Providing a suitable environment for our finned friends in captivity might just mean dimming the lights.

7. Ecosystem Disruptors

While goldfish may seem like the ultimate introverted and peace-loving artists of the aquatic world, painting with the gentle strokes of their fins and entertaining their aquatic pals with silent poems, it turns out they aren't entirely harmless in certain situations: Upon their release into the wild, goldfish transform into ravenous eaters and resource hogs, disrupting native ecosystems and making everything a bit less peaceful and picture-perfect for their fellow fish.
