Can you raise fish by hydroponically growing pennywort? What hydroponic plants can you use to raise fish?

1. Is it possible to raise fish?

You can raise fish when growing pennywort hydroponically, because it has a very strong growth ability and raising one or two small fish in the container will not have any impact. In addition, plant growth requires nutrients to maintain. If you raise fish, the fish excrement can meet the needs of the plants. Because fish excrement is a diversified organic fertilizer, it is easily absorbed by plants.

However, be careful about the lack of oxygen. Both pennywort and small fish require oxygen to grow. If there is a lack of oxygen in the water, the farmed fish will die. Therefore, we need to change the water every 2-3 days to avoid the problem of insufficient oxygen. You can also add oxygen to the hydroponic container, but relatively speaking, changing the water is more convenient.

2. What hydroponic plants can be used to raise fish?

Many hydroponic plants can be used to raise fish. Common ones include green ivy, lucky bamboo, smooth sailing, monstera, pennywort, and weeping angel. These plants are easy to grow and can be used to raise fish for viewing. When raising fish in hydroponics, try to choose small fish, and do not raise large fish together with hydroponic plants. And the number of fish should not be too many, 1-3 is best.
