Fish feeling frisky? Best cover up your aquarium

When fish are in the mood for love, they can get pretty excited. If you’re keeping them in an aquarium, this can result in them jumping out of the tank to an untimely death.

The behaviour is useful in the wild as it helps them find a spot to lay their eggs safely away from predators. This behaviour can be seen, for example, in the splashing tetra, a tropical fish, explains the Central Association of Zoological Specialists in Germany (ZZF).
