Hydroponic flowers living in symbiosis with fish, growing flowers and raising fish, two benefits in one

People today chase novelty, and growing flowers is no exception, with all sorts of variations, such as raising fish beneath hydroponic plants. This creates a natural beauty that combines the dynamic with the static, and the natural with the artificial. If you also like growing plants this way, why not read on!

First, fish need a great deal of oxygen to grow, and in a container of hydroponic flowers and plants, the roots also take their oxygen from the water, which creates a conflict over oxygen between the two and often causes fish to die from a lack of oxygen. So when growing flowers and fish together, never put in too many fish; generally 1-3 fish per hydroponic vessel is enough, and they must be small fish no more than 3 cm long.

Second, whether the nutrient formula and its concentration in the water are reasonable will also affect the growth of the fish. Generally, as long as the nutrient solution concentration is below 0.5 mS/cm, the chemical harm to fish is not great, and for some fish that are harder to keep, no nutrient solution needs to be added at all; you only need to fertilise within the plant's planting basket, that is, at regular intervals drip a suitable amount of nutrient solution onto the substrate in the planting basket. Or for plants like cactus that do not need nutrient solution themselves, since the large body can provide plenty of nutrients for root growth, they can be cultivated for several years even without adding any nutrient solution to the water.

In addition, put little or no ammonium nitrogen in the nutrient solution; usually use nitrate nitrogen as the nitrogen source in the formula, so that the nutrient solution has slightly less effect on the fish. There are also particular points in choosing fish species: containers with a large space can keep delicate goldfish, while containers with a small space can only keep hardier ornamental koi or tropical fish. If you adopt the flower-and-fish co-cultivation model, you must change the water frequently and feed sparingly to ensure the water stays bright and clear; otherwise, the large amount of waste the fish excrete will make the water cloudy and degraded, which neither adds to the beauty nor does the plants any good, and it would be better to just enjoy the roots.

Summary: growing flowers and fish together in hydroponics is an innovation in concept and in aesthetics; from a biological point of view it is actually neither good for the fish nor good for the plants, but the beauty of nature gathered in a single bottle or vessel still has its own unique value.
