It is characterized by its petite size, rich colors and meekness. Most of them have fat fins, only a few of them. Some species need to live in a dark environment.
The range of common people's cognition of Lampetraceae has spanned a considerable range in scientific classification, and this collective noun has replaced the scientific name. Generally speaking, it includes several families of Cyprinidae and some fish species of Cyprinidae. Characiformes are classified because there is a small lipid fin between dorsal fin and caudal fin. Scholars still don't know what the function of this lipid fin is. Of course, there are many families under the genus Lipid Carp. At present, there are 14 families, but it doesn't mean that all these 14 families are the lantern fish that everyone thinks. The common red lotus lantern (Paracheirodon axelrodi) belongs to the family Characidae, and this family is also the backbone of the lampfish, so we will also hear some people call it "Gallasin". In addition, the silver swallow (Gasteropelecus sternicla) belongs to the family Gasteropelecidae, the pointed pencil (Nannobrycon eques) belongs to the family Lebiasinidae, and the pearl lamp (Poecilocharax weitzmani) belongs to the family Crenuchipae. Characidium fasciatum belongs to Characidiidae, and some of these fish species belonging to the family Lepidoptera are also commonly called "〝Tetra〞" abroad, while they are called "American Lampetra" in China, because their origin is in the Amazon River basin of South America. As for the fish that are not lampreys, there are the Serrasalmidae of the piranha (Serrasalmus nattereri), the Citharinidae)… of the six clowns (Distichodus sexfasciatus), etc., because they are huge in appearance and fierce in temperament, which are different from the lampreys in everyone's mind. Cyprinidae (Cypriniformes) also belongs to the range of lampreys, but the range of cyprinidae is very large, among which the smaller one is considered as lampreys, and the most common ones are zebras (Brachydanio rerio), Rasbora heteromorpha and Tanichthys albonubes, because the hometown of cyprinidae is in Southeast Asia. What fish are included in the large CYPRINIDAE? Of course, everyone is most familiar with koi fish. It is emphasized here that the common red-tailed black shark (Labeo bicolor) belongs to CYPRINIDAE, but it is not what we think of as lantern fish, because it is a little bigger and its body is not glowing, while the Botia macracantha belongs to the loach family of CYPRINIDAE, and it does not belong to lantern fish. In addition, the blue-eyed lamp (Aplocheilichthys normani), which is often regarded as the family Lepidoptera, actually distinguishes the single-fingered family (Aplocheilidae) in the order from the scope of the family Lepidoptera that we have recognized. However, some players think that the rainbow fish "Australian lamprey" belongs to the family Melanotaeniidae, which lives in Australia with its quite special lifestyle and different body structures (two dorsal fins and rising pectoral fins) and has a further relationship with lamprey. However, there are many people who think that these fish are lampreys. In fact, there is no need to forcibly distinguish the scope of lampreys. After all, the term "lampreys" is not an academic classification, but an imaginary classification in everyone's mind. Since it is imaginary, it has little to do with biology. For a long time, everyone has decided that as long as it meets the requirements of "small size" and "luminescence". The origin of lamprey is widely distributed because of its interdisciplinary characteristics. Of course, the most important lipocyprinidae is still distributed in the Amazon River basin, but there are also lamprey in the Congo River basin in Africa. As for the hometown of CYPRINIDAE, it is in Southeast Asia, and its small and lovely traces can be found in Mekong River, Zhaopidai River and its tributaries. The characteristics of lantern fish Speaking of the characteristics of lantern fish, everyone must be impressed by their small and shiny bodies, right? In addition, because of their small size, they swim in groups in order to resist the attacks of other fish species. Hundreds of spectacular pictures are beautiful when swimming in fish tanks! Some people think that the reason for group swimming is to make the group look huge and make other fish species dare not invade rashly; Some people think that group swimming is to keep the vigilance of the group. As long as one lantern fish finds that the situation is different, other lantern fish will immediately notice and swim away, which is quite a feeling of helping each other. If the group swimming lantern fish can be matched with lush aquatic plants and bright lights, it will highlight the aesthetic feeling of lantern fish different from other fish species.
