? When zebrafish lack oxygen, they need oxygen to increase oxygen. Zebrafish is a high-oxygen animal, to ensure that the oxygen in the water is sufficient, when the oxygen in the water is insufficient, it must be oxygenated, because zebrafish will not surface to breathe, long-term oxygen deficiency, will be in a state of hypoxia, easy to lead to the death of fish.
zebrafish 1. Feed: Shrimp, paramecium, red nematode and frozen red worm are the favorite foods of zebrafish. Generally, adult zebrafish can be fed twice a day, while small zebrafish need to crush the food before feeding. Tropical fish feed can achieve the purpose of satiety, but the nutrient content is low, zebrafish may not grow so fast after eating.
2. Temperature: Zebrafish is a tropical freshwater fish, which is most suitable for growing at 22-28 degrees. Temperature should not be too high, too high temperature will reduce the dissolved oxygen in the water, easy to breed bacteria in the water, zebrafish will be sick, too low temperature zebrafish growth and development slowed down, reduced spawning.
3. Illumination: The suitable illumination cycle of the zebrafish breeding system is a 14-hour illumination cycle and a 10-hour dark cycle. The illumination system should be gradually bright and dark to avoid stimulating the zebrafish and prevent the zebrafish from jumping out of the fish tank. The light intensity should be in the range of 54 to 324 Lux to avoid insufficient light. The stripes of zebrafish are dark and lack of vitality.
