The scientific name of the hexagonal dinosaur fish is Mexican salamander, which is an omnivore. Main food: algae, worms, insects or small fish and a small amount of other fish droppings. Feeding, you can feed all kinds of foods that are easy to find, including: dried rice, noodles, chicken, pig brain, chicken liver, various fish, and for convenience, you can also feed frozen or fresh blood worms, earthworms and wax worms. It is ok to feed cattle hearts, but it should be noted that animal protein is not easy to digest. Young blunt-mouthed salamander can be fed with Daphnia, shrimp or fish (cut into small pieces) until it grows up and can eat bigger food.

Blunt-mouthed salamanders use their sense of smell to find food. They will "stick to food and suck with the vacuum force in the stomach." Therefore, young blunt-mouthed salamanders cannot be kept with other animals. They will bite each other, even if they are of the same species, but they can keep adult blunt-mouthed salamanders together. Fish bite their cheeks when they sleep, causing inflammation.

Note: it is forbidden to mix with all fish, shrimp, turtles, etc. (The small fish fed to the blunt-mouthed salamander need to be cut off), the cheeks are eaten up, the skin falls off and even dies (mixed with the scavenger, the blunt-mouthed salamander will secrete mucus, which will cause the scavenger to suck on the body and cause a piece of meat to be sucked off). Even if they are kept together, they should be fed to every adult (live animals, such as red worms, are put in fish tanks)

Mexican salamander (Axolotl), also known as American salamander, commonly known as hexagonal dinosaur, is an aquatic amphibian and endemic to Mexico. The natural environment can only live in muddy waterways and lakes. It is famous for its unique appearance and mature larvae. That is to say, even after sexual maturity, it will not change to adapt to the land and still maintain the aquatic form. Although they are kept as pets all over the world (especially in North America and other places), their original habitats have been developed in large quantities, resulting in sediment at the bottom of the lake, destroying the silt environment at the bottom of the lake and causing functional extinction. The living area does not exceed 10 square kilometer. It is listed as an extremely endangered species in the red list of the World Conservation Union.
