How long can the scavenger fish live?

The lifespan of scavenger fish is long and short, generally the shortest is one year, and the longest has not been found yet. However, as long as the scavenger fish does not leave the water, adequate feed and the right temperature of the water will live a long time. Because when there is not enough food, the scavenger fish will starve to death. When the suitable water temperature is below 20 degrees, the scavenger fish will freeze to death. Alkaline water quality will kill the street sweeper.

Why did the scavenger fish die?

1. No fish food will kill the scavenger: the scavenger fish is omnivorous and likes to look for food at night, so keep enough food in the bathtub at all times to prevent starvation.

2. Too low water temperature will kill the scavenger fish: the scavenger fish likes to grow in an environment with a water temperature of more than 20 degrees. If the temperature is lower than 20 degrees, it will freeze to death. Especially in winter, it is very difficult for street sweepers to survive the winter, so the water temperature must be controlled.

3. The alkaline water quality will kill the scavenger fish: the scavenger fish likes to grow in weak acid soft water, but if the water quality is too alkaline, it will make the scavenger unable to adapt and die. Therefore, if there are conditions, tap water placed in the sun for two days is the best. If there is well water, it is best.

4. Poor water quality will lead to the death of scavengers: scavengers like to live in a clean environment, so they can replace water every 7 days or so, and 20cm every time, which is conducive to the growth of scavengers.

5. Pouring water directly to the scavenger fish will kill the fish: when changing water, try to avoid pouring water on the fish, so as not to kill the fish.

6. Adding salt to the water will kill the scavenger fish: the scavenger fish is not salt-tolerant, so don't add salt to the water during the breeding period, so as to avoid the scavenger fish dying. In addition, if salt is added to the water, alkaline substances will be formed, which will change the water quality and lead to the death of scavenger fish.
