In modern life, the image of traditional water tanks has become unfamiliar to many, especially the younger generation living in cities. However, water storage tanks remain an essential item for rural households even today. When piped water was not common, each family would have a tank to store well water, rainwater, or spring water. With the development of municipal water supply systems, these tanks have gradually been replaced; many have been discarded, while others are repurposed for growing lotus or raising ornamental fish.
In this context, a remarkable story has captured the attention on social media regarding a carp that has lived in a water tank for 10 years without anyone feeding it. What happened that allowed this fish to survive for such a long time? This is a rare phenomenon that raises many questions about the biology and living conditions of carp.
1. Can Carp Live for 10 Years?
This species is known for its strong vitality.
First, to answer this question, we need to understand the lifespan of carp. In natural conditions, carp can live from 10 to 15 years. This species is famous for its resilience, particularly in the wild, where its lifespan can extend up to 15 years if the living conditions are favorable. Therefore, it is not surprising biologically that a carp can live for 10 years in a water tank.
However, the remarkable aspect of this story is that the carp survived for 10 years without being fed, which is hard for many to believe. Could it be that it survived due to some special ability, or were there indeed unnoticed food sources available?
2. The Living Environment of Carp in the Water Tank
An important factor to consider in this case is the living environment of the carp in the water tank. If you have ever visited a market, you may have seen fish tanks equipped with aeration devices to supply oxygen to the fish. Just like terrestrial organisms need oxygen to breathe, fish in water also require oxygen to survive, which they extract from water through their gills.
In natural conditions, if there are too many fish in a confined space, the oxygen levels in the water may not suffice for all of them, leading to a phenomenon known as fish suffocation. Therefore, fish tanks in markets are often equipped with aeration devices to supplement the necessary oxygen levels.
In the case of the carp in the water tank, it may not be necessary to use aeration devices, as rural water tanks have a large capacity, typically around 300-500 liters. It is estimated that a carp requires about 4-5 mg of oxygen per liter of water to survive, and with such a large volume, the oxygen levels in the tank are sufficient for it to exist without human intervention.
The fact that the fish does not need to be fed but still lives is difficult to explain.
3. Living Conditions and Food Sources
One of the most surprising aspects for many is the fact that the carp lived for 10 years without being fed. According to the law of conservation of energy, to survive, fish need to intake energy through food. The fact that the fish can survive without being fed, and even swim around, is perplexing.
However, it is possible that during this time, the carp had access to food sources from the surrounding environment that went unnoticed. The water in the tank may contain plankton, a type of tiny microorganism that lives in water and provides nutrition for the fish. Additionally, insects falling into the tank could also serve as natural food for the carp.
This is also evidenced by the historical practice of raising fish in water tanks since ancient times. Some tea houses would keep carp in water tanks to check the water quality. When they saw the carp thriving, they could be assured that the water was clean and safe. Carp are often released into tanks without being fed, and they can survive on the natural nutrients available in the water.
The story of the carp surviving without food also evokes the tradition of raising carp in wells in rural areas. In some regions, people place carp in wells to help purify the water. Carp feed on plankton and insects in the water, contributing to maintaining cleaner water quality.
In these cases, carp act as a “guardian” for the water source. If one day the carp dies, the residents will realize that the water has become polluted and is no longer usable. This illustrates the strong vitality of carp in harsh conditions, demonstrating that even without external food sources, they can sustain life.

4. Carp – A Symbol of Resilience
The story of the carp living for 10 years in a water tank without being fed is not only a strange phenomenon but also a testament to the remarkable vitality of this species. Despite enduring a long time without human intervention, carp can survive thanks to the natural environment and the trickle of food they inadvertently receive.
The strong survival ability of carp not only surprises us but also opens up many insights about the relationship between living organisms and their surrounding environment. In harsh natural conditions, this species has developed remarkable adaptive mechanisms that allow them to exist even in the most challenging environments.
The story of the carp in the rural water tank not only reminds us of old memories but also serves as a reminder of the persistence and incredible adaptability of nature. Regardless of the passage of time, creatures like carp continue to exist quietly, preserving and reflecting the vibrant life of the natural world around us.
