1, depending on the size
The hexagonal dinosaur fish growing in the same environment, the male fish looks slender and slim. The female fish's body is plump and fat. Compared with the two, it is easy to see. The hexagonal dinosaur is not a real dinosaur, but a small salamander with the appearance of a dinosaur.
2. Look at the drainage hole
The reproductive pores of male hexagonal dinosaur fish are more prominent, and they are also more obvious in adulthood, but their excretory pores are far from their hind legs. The female fish's reproductive hole is relatively flat, but the position of the drainage hole is relatively close to the hind leg. It's hard to find if you don't observe it carefully.
eating habits
Mexican salamander is an omnivore. The main food is algae, worms, shellless insects or small fish and a small amount of other fish droppings. In feeding, you can feed all kinds of foods that are easy to find, including chicken, various fresh water fish and fresh water shrimp. For convenience, you can also feed frozen or fresh blood worms, earthworms and wax worms.
Other foods with high protein, low fat and no hard shell and thorns, high starch foods are forbidden, and processed products such as ham sausage and cooked meat eaten by people must not be fed. The juvenile blunt-mouthed salamander can be fed with Daphnia, shrimp or other freshwater microalgae until it grows up to eat larger food. Blunt-mouthed salamanders look for food with their sense of smell. They will approach the food and suck it with the vacuum force of the abdominal cavity. Therefore, underage blunt-mouthed salamanders can't be kept with other animals, they will bite each other.
