Inertial slide transitioning to slow speed region. This is a world that ordinary floating and sinking minnows do not have. For existing minnows, repeat the movement → stop → movement → stop with a twitch etc. When you stop, you try to use buoyancy (even when sinking there is buoyancy to correct your posture), and you do not move forward, and as a result, you come to a halt. Due to its own weight, D-CONTACT twists forward even as it tries to regain its posture due to the law of inertia. This is an inertial slide. After that, it moves to the slow speed region. In the sequence of motion → inertia slide → motion → inertia slide, fish are attracted by the "movement" and recognize the slow but moving inertia slide to the slow speed region as a bite opportunity. The same thing can be felt when we see birds and animals catching prey.
