Скачать или смотреть This Aquarium Fish Jumps Out of Tanks

Arowanas look calm, elegant, and controlled — until they aren’t.

This surface-hunting fish is built to strike upward with explosive force. In home aquariums, that instinct turns into shattered lids, bent covers, injured fish, and sometimes injured owners. Sudden light changes, movement near the tank, or surface activity can trigger a powerful jump with no warning.

Watch the full video to see which dangerous aquarium fish are NOT SAFE to keep, and why peaceful-looking tanks can turn chaotic instantly.
