Fish in ecological bottles can live for about half a month, but some small fish can live in ecological bottles for about 1 year.

The first day when a small fish enters an ecological bottle is a dangerous period. As long as you can survive in an ecological bottle for 2-3 days, you can basically survive for a long time.

The space of ecological bottle is small, so it should be noted that the number of fish should not be too much to avoid the problems of hypoxia and water quality deterioration.

Fish culture skills in ecological cage

1. Farming quantity: Eco-bottle farming needs to control the farming quantity, because there is no filtration and oxygen in the eco-bottle, and the water quality tends to deteriorate if there is too much farming quantity. Therefore, 1-2 small fish can be cultured in ecological small bottles, and it is difficult to survive if there are too many.

2. Ecosystem: If you want the fish in the ecological bottle to survive better, you need to build a good ecosystem in the bottle, so that the fish can grow normally even without oxygenation and filtration. However, once the ecosystem is destroyed, it is difficult to rebuild, so it is necessary to adjust the ecosystem before raising fish.
