Dinosaur fish is a type of Pangea fish with a long history, which can be seen from its name. Dinosaur fish is a fish that can be compared with dinosaurs. It can also be regarded as a living fossil among fish. From its size, we can also see its antiquity. Like other aquarium fish, many issues must be paid attention to when raising dinosaur fish.
1. Environment
The structure of the body of dinosaur fish is relatively soft, so the size requirements for the living environment are not so strict. For small ones of about 30 cm, For species, a 60 cm tank is sufficient. However, for good growth, the larger the water body, the better. For complex species such as dinosaur kings and large-flowered dinosaurs, they must be raised in large aquariums. If they want to grow to 50 centimeters or more, it is best to prepare a tank of more than 1.5 meters. If possible, you can landscape them in the fish tank, lay some bottom sand, put a piece of heavy wood or the like (heavy wood is a good item, it is said that it can release chemicals in the water that calm the fish's mood, and it itself can You can provide a hiding place for the fish), or you can put some PVC hollow pipes for them to hide. Dinosaur fish are in good health, but if the nitrate concentration in the water decreases, their resistance will be weakened, so partial water changes must be continued.
The water quality in which dinosaur fish lives needs to be safe
Dinosaur fish have strong adaptability, but rapid changes in water quality will affect their appetite. Therefore, some When changing the water, be sure to add neutral new water. The suitable water temperature for adult fish is 20-25℃. If the water temperature gradually drops to 20℃, it will not cause harm to dinosaur fish. The water temperature during the juvenile period should be maintained at 25-26°C, or a slightly higher temperature is more suitable for growth.
2. Feeding
Dinosaur fish are not too picky about food. When they are young, they can be fed red worms, earthworms, etc., and when they are a little older, they can be fed lepidopterans and pellets. food, or fish meat, fish intestines, fish liver, etc.; after growing into adult fish, they can be fed goldfish, crucian carp, small big head shrimp or fish fillets. In order to facilitate feeding, in addition to feeding raw bait, it is best to feed local artificial feed.
Dinosaur fish eat a lot of food. If the bait they feed is not enough, it will harm other fish. Therefore, when raising them together, it is best to feed them separately. Giant cyprinids, cichlids, catfish and other fish can be kept together with dinosaur fish. However, it should be noted that lungfish among pangea fish cannot be kept together with dinosaur fish.

3. Other feeding knowledge
Dinosaur fish are not afraid of lack of oxygen. Dinosaurs The swim bladder has evolved into an auxiliary respiratory organ (this phenomenon is rare among pangu fish, such as walruses, bowfins, swordfish, Nile monsters, crocodiles, lungfish, etc. all have this characteristic), so it When there is not enough oxygen in the water, just take a few breaths of air. You can often see dinosaur fish swimming to the surface to breathe air.
The body surface of dinosaur fish is covered with diamond-shaped hard scales, forming a protective layer. Therefore, dinosaur fish can tolerate poor water quality, has good drug resistance, and rarely gets sick. However, this does not prove that dinosaur fish are immune to all poisons. If you want to raise a good dinosaur fish, you still need to give it a good environment. Although its adaptability is super strong, it will die if it exceeds the limit of its tolerance. For small dinosaur fish, it is more important It should be noted that immature dinosaur fish have poor resistance to pesticides and salt.
Dinosaur fish are grassroots fish, so you can keep some middle and outer fish in mixed culture. However, be careful not to have different sizes, because dinosaur fish are not kind creatures, and you can keep them when they are hungry. Eat big fish. In addition, you should also pay attention to the fact that dinosaur fish will be killed by other fish, so it is recommended not to mix it with red-tailed cats, tiger-bill duckbills, etc.
Some people like to keep fish in a polyculture. It should be noted that dinosaur fish must not be kept in a polyculture with lungfish. Lungfish will attack dinosaur fish crazily. Although dinosaurs are protected by hard scales, they are also hostile to dinosaurs. There are no bigger teeth than the lungfish.
