Like all animals, fish spend some of their life sleeping. However, no other fish sleep in quite the same way as the clown loach and its close relatives; they take their naps lying on their sides on the bottom.
The clown loach’s atypical resting disposition was absolutely unknown until an aquarist spotted it in one of his particular fish. The clown loach was lying on its side, hardly breathing, and looking as if it was close to death.However, as soon as the clown loach was disturbed, it simply “got up” and swam away in typical fashion—at lightning-fast speed. Since then, this unusual behavior has been well documented.
