Nowadays, the chance of people eating shrimp is not low; whether having a hot pot or ordering a bowl of pot-cooked noodles, there is often an opportunity to eat shrimp. However, having the experience of raising small shrimp is not something everyone has. Today, I want to share a post that a Twitter user recently shared online, which has already accumulated over 27 million views. The post mainly talks about his own experience raising Hawaiian red shrimp in a spherical ecosphere for more than 15 years without the shrimp dying. Is this normal?
The Twitter User's Story
The user's tweet roughly says that just a few days ago, he shared a story on Twitter (X) that he calls a "scary story" (don't worry, no ghosts involved). When he was in first grade, he bought a small round bottle containing five little shrimp. Not long after, four of them died one by one. But the problem was that the one remaining shrimp seemed immortal, surviving continuously. The user is now 23 years old, and even his dog, who is the same age, has passed away and gone to heaven. So why is the shrimp still alive? Has it learned Japanese? Could it be an alien in disguise, possibly here to monitor his household?
Biological Perspective and Community Feedback
Is there any biology expert who can help explain this? The shrimp has been kept in the living room at home, with only occasional tap water added, yet it has survived through winters and summers for 15 years. Is this reasonable? What kind of creature is this?
After some online research, it appears that what the user bought is a type of ecosphere. This ecosphere is basically a small closed ecosystem where the pre-set environment supports the survival of the plants and animals inside. The main maintenance is just occasionally adding water. Regarding feeding, according to netizens, as long as the shrimp are not eaten and successfully molt, they can live indefinitely, surviving just by consuming algae inside the bottle. Therefore, they can live for an extremely long time.
Additionally, this tweet attracted many other users who have bought similar ecospheres, and their experiences are similar to the original poster's. Basically, under conditions of just placement and occasional water addition, the shrimp seem to have infinite lifespans.
Shrimp Breeding in Ecospheres
Some users even reported that their shrimp populations have grown over time, with shrimp reproducing inside the ecospheres by themselves.

In summary, this is the content shared this time. Have any of you in front of the screen ever bought a similar ecosphere? Are the Hawaiian red shrimp inside them generally very long-lived?
