Introduction to the species of pike
The dorsal fin of B is similar to that of cichlids, and the whole fin is connected with the dorsal ridge. The dorsal fins of a and C are triangular, like sails of sailboats standing on the back of a rat. The appearance of a-genus rat fish is similar to that of c-genus rat fish. It is impossible to distinguish which genus it is from the shape of dorsal fin. It can only be said that most a-genus rat fish are relatively slender, but the overall length is only about 4cm, and most of them are black spots or patches.
Among the c-genus rodents, the most difficult thing to distinguish is the spotted leopard rat group, which often leads people to unconsciously fall into the 'leopard rat myth'. When identifying the members of the leopard rat group, we should pay special attention to the thickness and arrangement of the spots on the side of the body. In addition, the golden block in the neck, color and width are also the important basis for discrimination. The black block at the junction between the base of the dorsal fin and the back should also be considered. The rat fish that has been classified has its own Latin scientific name. Each importer uses its own set of methods to identify and name the rat fish. Olive catfish group, representative species: XO rat, coffee rat, panda rat, red headed rat, English gerbil, tabby rat, red twill rat, red black belt rat, obergen rat, new red twill rat, large red headed rat, long snout red headed rat, golden wing emperor rat, sweet mouse (baby rat), Indian mouse (Archer rat), bow backed mouse (mask rat), etc.

The chipmunk fish is one of the most robust tropical fish. Generally, whether the chipmunk fish can live for a long time will be decided within one week after import. After the wild chipmunk fish are collected, they are first removed from the stomach stock in the distribution center. The so-called "elimination of stomach" is a term used by importers and exporters. In order to avoid the deterioration of water quality caused by the discharge of fish under high-density packaging and transportation, and even the death of the whole bag of fish, the process of fasting the fish to be shipped is called "elimination of stomach". Don't buy big head and thin body fish. Although there is still a chance for the starved fish to get fat, most of the starved fish are weak in physical strength and lack of resistance, and the parasites in their bodies are waiting for the opportunity to reproduce in large numbers. There are far more dead fish than starved fish. The typical symptoms of parasite infected fish are sunken eyes, white spots on the head and body.
Don't buy chipmunk fish with sunken eyes. The sternal spines of the chipmunk fish will secrete venom, which will cause chronic poisoning of the chipmunk fish if dissolved in the water. However, it is not only when the chipmunk fish is packaged in a bag, they will put venom to kill themselves. Generally speaking, the chipmunk fish will secrete venom only when they are severely frightened. Therefore, it is urgent to catch the chipmunk fish with poor technology before packaging, and the packaging density is too high It will cause the fish to secrete venom, but the poisoned fish is not easy to distinguish in a short time. What's worse, the survival rate of the poisoned fish is almost zero. If it can wait for one to two weeks in the aquarium to be stored in the aquarium, it is the best way to buy back healthy individuals. However, if it is a rare species that must be bought, you can carefully observe the swimming posture and breathing situation of the fish.
