鱼的第七秒是重生
[yú de dì qī miăo shì zhòng shēng]
This name 'The seventh second for fish is a rebirth' derives from the myth that a goldfish has only a 7-second memory span, implying they would forget all the unhappy moments within 7 seconds and thus 'be reborn' constantly as if all starts anew every seven seconds. This nickname may express the owner's pursuit for renewal, letting bygones be bygones.
