Red-tailed catfish is a common ornamental fish. Its Chinese name is red-tailed catfish. This fish has three colors, gray-black back, snow-white belly, and orange-red tail. There is a white line from the snout to the tail. The fish's tail and dorsal fin are both crimson red, the other fins are blue-black, and the upper part of her eye sockets are white. Red-tailed catfish are very afraid of light, so they can generally only be seen at night, and because the lights are not available at night, they are easy to bump into. Of course, there are also some artificially bred ones that do not have the habit of walking at night. Although this kind of fish looks pretty, it actually has a very ferocious character. It especially likes to eat small fish. When there are no fish to eat, it will eat some live food or pieces of meat, as well as animal bait. This kind of fish will have obvious collective feeding habits when feeding food, and it is also relatively easy to raise. The most amazing thing is that when it reaches sexual maturity, the red-tailed catfish can also make a cat-like sound. Another point is that when catching fish, this kind of fish may temporarily fade due to fright, if you have this kind of fish at home. You can try it. Let me remind everyone that red-tail catfish is a carnivorous fish in the Amazon river and is an exotic species. The release of red-tail catfish is expressly prohibited in my country, so if you purchase red-tailed catfish, you cannot release it, which is illegal. We mentioned earlier that this fish eats small fish, so once it is released, Bao Buqi, the red-tailed catfish, will eat all the small fish in the local fish population. Moreover, it has a strong reproductive capacity. If it is released, it may reproduce in a large area. In addition, red-tailed catfish is also relatively easy to get sick. Therefore, some people do not like to keep this kind of fish. If you see this kind of fish in the wild, you can tell the relevant local departments and let them pay attention. After all, once this kind of fish enters our waters, it will most likely pose a threat to our ecosystem, so either catch it and eat it, or deal with them all.
