A valuable arapaima gigas unexpectedly leapt out of its tank and died at an aquarium in northern China.

The CCTV footage was filmed in Laiyuan County in Hebei Province on June 4th.

The airport arapaima gigas fish, a star exhibit at the aquarium for six years, measuring 1.6 metres in length and valued at around 50,000 yuan (£5,400), broke through the tank cover, leaving everyone present stunned.

According to Mr. Sun, the aquarium's manager, they heard a noise and turned to see the fish tank area in disarray, with the fish flopping on the ground and knocking over some flowerpots.

Despite swift efforts to return the fish to the tank for rescue, it tragically succumbed to internal injuries.

The aquarium expressed deep regret over the incident, describing the fish as a cherished member of their establishment, akin to losing a close friend.

To honour and remember the fish, they plan to preserve it as a specimen for permanent display.

The incident sparked discussion online, with some expressing regret over the loss of such a valuable ornamental fish.

Experts suggest that the fish's escape may be related to factors such as environmental stress, water quality, temperature, and instinctual behaviour.

近日，位于河北省涞源县的中庆水族馆内发生了一起罕见事件，一条价值不菲的巨骨舌鱼意外从鱼缸中跳出，引发了广泛关注。

据了解，这条巨骨舌鱼是馆内的明星展品，已经饲养了长达六年之久，长达1.6米，价值约为五万元人民币。它不仅具有极高的观赏价值，还承载着饲养者的深厚情感。然而，6月4日下午，这条巨骨舌鱼突然冲破鱼缸盖，跳到了外面，让在场的所有人都惊愕不已。

据水族馆负责人孙先生介绍，他们听到异响后立刻转头查看，只见鱼缸旁边一片狼藉，巨骨舌鱼在地上来回摆动，还打翻了一部分花盆,。尽管大家迅速反应，尝试将鱼放回鱼缸进行抢救，但不幸的是，这条珍贵的巨骨舌鱼最终还是因内脏受损伤势过重而死亡。

对于这次意外，水族馆方面表示深感遗憾。他们表示，这条巨骨舌鱼已经成为他们水族馆的一部分，失去了它就像失去了一位亲密的朋友。为了表达对这条鱼的敬意和怀念，水族馆计划将其制作成标本，永久展示在馆内。

此事件也在网络上引发了热议。有网友表示惋惜，认为这是一条非常有价值的观赏鱼，就这样失去实在可惜。也有网友调侃称，这条鱼可能是患了“抑郁症”，才会做出如此异常的举动。

专家分析认为，巨骨舌鱼跳出鱼缸的原因可能与其生活环境的压力、水质、温度以及鱼类的本能行为有关。他们建议水族馆在饲养大型观赏鱼时，应提供更加宽敞和适宜的生活环境，同时定期检查水质和温度等条件，以确保鱼类的健康和稳定。
