龙鱼日常饲养过程中的注意事项

龙鱼（详细介绍）饲养龙鱼时，从龙鱼闪亮的鳞片可以看出它们是否健康，科学的饲养方法和帮助它们获得自然光的照明也是龙鱼养殖中非常重要的饲养点。小编将简要介绍一些饲养龙鱼的方法。研究表明，龙鱼的毛色受鱼鳞下真皮中的色素细胞（生色细胞）和表面的鸟苷的影响。真皮中散布着各种细胞，它们可以随着光的强度或环境的变化而膨胀和收缩。各种色素细胞具有吸收和反射光波长的功能。因此，在不同的光环境中会出现不同的颜色。此外，龙鱼的显色性也会在不同的光照强度下发生变化。例如，如果龙鱼暴露在强光下，色素细胞会伸长。当色素细胞伸展时，色素会随着细胞周围的辐射而膨胀。色素细胞的面积会扩大，颜色也会显著加深。如果有更多的红色颜料，颜色会变得更暗、更红。在相反的情况下，如果龙鱼暴露在昏暗的光线下，色素细胞收缩，色素细胞萎缩，色素分子变小，颜色也会明显褪色。同时，色素会随着细胞的收缩而集中，有时甚至收缩成微小的斑点，其颜色自然会变得苍白或不明显。首先，坚持每周给龙鱼换水。换水时要注意提前提水，并调整新水的温度、PH值等标准，使其与老水一致，达到龙鱼的生存标准。不建议每周更换所有的水，但每次只能更换20%-30%的水。换水时，应先抽出旧水，然后沿鱼缸壁缓慢注入新水。第二，龙鱼需要足够的照顾。饲养龙鱼最好购买合适的灯棒，每天给龙鱼照明6-8小时。值得注意的是，对龙鱼来说，最好的光线是白天的日光。如果长时间使用灯光，会使龙鱼的背部变暗。所以，如果条件允许，我们应该让龙鱼得到更多的阳光。最后，我们需要定期定量地给龙鱼喂食。还应根据龙鱼的实际情况选择合适的食物。简单来说，未成熟的幼银龙鱼在选择食物时应该选择一些小面包虫、血虫等食物。当龙鱼长大后，它们可以吃一些肉、虾和其他食物。当然，在喂养龙鱼时，我们在选择食物时也要注意多样化。专业饵料和活饵有机搭配，满足龙鱼的生长和饮食需求

Points for attention in the daily feeding process of arowana

arowana (detailed introduction) When raising arowana, you can see whether they are healthy from the shiny scales of the arowana, and scientific feeding methods and lighting to help them get natural light are also very important feeding points in the breeding of arowana. The editor will briefly introduce some methods for raising arowana. Research shows that the hair color of arowana is affected by the pigment cells (chromogenic cells) in the dermis under the scales of the fish and the guanosin on the surface. There are various cells scattered in the dermis, which can expand and contract with the intensity of light or the change of environment. Various pigment cells have the function of absorbing and reflecting the wavelength of light. Therefore, different colors will appear in different light environments. In addition, the color rendering of arowana will also change in different light intensities. For example, if the arowana is exposed to strong light, the pigment cells will stretch out. When the pigment cells stretch out, the pigment will expand with the radiation around the cells. The area of the pigment cells will expand, and the color will also significantly deepen. Where there is more red pigment, the color will become darker and redder. In the opposite case, if the arowana is exposed to dim light, the pigment cells shrink, the pigment cells shrink, the pigment molecules become smaller, and the color will also significantly fade. At the same time, the pigment will concentrate with the contraction of cells, sometimes even shrink into tiny spots, and its color will naturally become pale or not obvious. First, insist on changing water for the arowana every week. When changing water, we should pay attention to raising water in advance, and adjust the temperature, PH value and other standards of new water to be consistent with the old water, and meet the survival standards of arowana. It is not advisable to replace all the water every week, but only 20% - 30% of the water every time. When changing water, you should draw out the old water first, and then slowly inject new water along the wall of the fish tank. Second, the arowana needs enough care. It is better to buy a suitable light stick for raising the arowana, and give the arowana light for 6-8 hours every day. It is worth noting that the best light for the arowana is the daylight in the daytime. If the light is used for a long time, it will darken the back of the arowana. So, if conditions permit, we should let the dragon fish get more sunshine. Finally, we need to feed the dragon fish regularly and quantitatively. The appropriate food should also be selected according to the actual situation of the arowana. To put it simply, immature young silver dragon fish should choose some small bread worms, blood worms and other foods when choosing food. When the dragon fish grow up, they can eat some meat, shrimp and other food. Of course, when feeding arowana, we should also pay attention to diversification when choosing food. Professional bait and live bait are organically matched to meet the growth and diet needs of arowana
