1. What fish is best to raise in clear water It is better to raise goldfish in clear water. Clear water is relative to green water. Although there is no fish when the water is clear, fish farming with clear water can still be raised. The effect of raising fish in green water will be better, because green water contains chlorella, which is not a threat to fish, and can also be used as food for some small fish. In addition, because algae belong to plants, they can carry out photosynthesis, thus producing oxygen, which is also helpful for fish to breathe.
2. How to raise green water by raising fish1. Illumination: If you want to raise green water, you must first provide sufficient illumination. Algae are also plants, which need photosynthesis for growth, and can't multiply in large numbers in dark places. Therefore, fish tanks must be illuminated for a long time, and they can usually be placed in sunny places, but attention should be paid to temperature changes to avoid excessive temperature difference between day and night.
2. Temperature: Because algae also have certain requirements on temperature, it can't be too high or too low, and it is usually better to keep it between 15-20 ℃. Of course, it is impossible to raise tropical fish at this temperature, but few people use green water to raise tropical fish, and generally raise goldfish.
3. Nutrients: In addition, it is necessary to cultivate green water nutrition, and it is actually very simple to provide nutrition. It is enough to rely on fish. After feeding it at ordinary times, its excrement is the nutrient for algae, so it is not necessary to clean the fish tank frequently, and the excrement is also conducive to algae outbreak.
