Note: Dear friends, due to the upgraded style of our waterproof fish toy, the appearance style and color will be a little different from the previous style. Please refer to the actual product received. If you have any questions, please feel free to contact me. Thank you for your support and understanding. Note: 1. Before use, check whether the waterproof gasket of the battery cover is fixed and whether the screws are tightened. Do not pull the fish tail during use. 2. After use, take out the small fish and dry it, take out the battery and keep it dry to avoid rust. 3. The small toy fish is not a real fish and cannot be placed in the water for a long time, which is easy to cause damage to the small fish.
