养龙鱼鳞颜色的要点

龙鱼鳞（细节）

龙鱼（细节）龙鱼鳞的颜色在整个上色过程中非常重要，龙鱼鳞色对龙鱼生长后的体色有非常重要的影响。那么养龙鱼鳞片的关键点是什么，需要鱼友们注意

龙鱼的毛色不是出现在鳞片的角质上，而是出现在裸露鳞片表面的一层大约0.1-0.2mm厚的鳞片上。也就是说，我们通常所指的鳞屑实际上包括鳞屑角质和鳞屑膜两部分。鳞片角质和鳞片膜的生长有自己的规律，其中鳞片角质的生长像树一样发生在鳞片圈区域的外侧，而鳞片膜的增长则发生在圆圈区域的中心。这就解释了为什么热带鱼的鳞片具有树环图案，龙鱼的背景颜色会发生变化。在鳞片生长过程中，外侧逐渐扩大，内侧逐渐被前鳞片覆盖。被覆盖部分的背景色随着鳞片膜从中心区域的不断分化而逐渐移动到外部更大的尺度区域，这就像大陆架上陆地的漂移。这使得背景色在被移动和稀释的过程中逐渐褪色。这种现象的严重程度也与背景区域中色素细胞的分裂周期和数量密切相关

Key points for raising the color of the dragon fish scale

Dragon fish (details)

Dragon fish (details) The color of the dragon fish scale is very important in the whole color process, and the color of the dragon fish scale has a very important impact on the body color of the dragon fish after growth. So what are the key points of raising arowana scales that need to be noticed by fish friends

The hair color of the arowana does not occur on the cutin of the scales, but on a layer of scales about 0.1-0.2mm thick on the surface of the exposed scales. That is to say, the scales we usually refer to actually include two parts of scale cutin and scale membrane. The growth of scale cutin and scale film have their own rules, among which, the growth of scale cutin occurs at the outside of the scale circle area like a tree, while the growth of scale film occurs at the center of the circle area. This explains why the scales of tropical fish have the tree-ring pattern and the background color of arowana shifts

The exposed part of the arowana scale is the circular part of the entire round scale with a 90-degree angle. In the process of scale growth, the outer side is gradually expanded and the inner side is gradually covered by the front scale. The background color of the covered part is gradually moved to a larger scale area on the outside with the continuous differentiation of the scale film from the central area, which is like the drift of land on the continental shelf. This makes the background color gradually fade in the process of being moved and diluted. The severity of this phenomenon is also closely related to the division cycle and number of pigment cells in the background area
