Dinosaur fish is a tropical freshwater fish, which is an ancient fish. The best tank for keeping dinosaur fish is over 100 centimeters. Since dinosaur fish like to dig sand, it is better to put 4~6 centimeters of sand at the bottom of the tank.
Dinosaur fish are strong, but if the concentration of nitrates in the water increases, their resistance will be weakened, so it is important to keep doing partial water changes.
Dinosaur fish are highly adaptable, but drastic changes in water quality can affect their appetite, so be sure to add neutral new water for partial water changes.
The water temperature suitable for adult fish is 20~25℃, if the water temperature slowly decreases to 20℃ it will not cause harm to the dinosaur fish. The water temperature during the juvenile period should be kept at 25～26℃, or slightly higher temperature is more suitable for growth.
Dinosaur fish are not too picky eaters, young fish can be fed red worms, earthworms, etc., and then feed scaly shrimp, granular food, or fish, fish intestines and fish liver, etc.; grow into an adult fish, you can feed goldfish, crucian carp, small prawns or fish flakes. In order to facilitate feeding, in addition to feeding raw bait, it is best to feed part of the artificial feed.
Dinosaur fish have a very large appetite and will harm other fish once the bait they are fed is not enough to eat, so it is best to adopt a decentralized feeding method when mixed feeding. The large-sized fish, such as the lipo fish, cichlid fish and catfish, can be mixed with the dinosaur fish, but it is important to note that the "lung fish" of the ancient fish cannot be mixed with the dinosaur fish.
Extended information:
Dinosaur fish is an ancient fish, and the same as the dragonfish, lungfish belongs to the fossil of the large fish. The body is strongly built, and different species grow at different rates. Feeding is not difficult, small fish, small shrimp live bait and fish worms are accepted, frozen Antarctic shrimp, fish particles of food can also be fed, basically not picky about bait?
Multifin and bowfin are both ancient fish, and both were relatively prosperous fish in ancient times, but after hundreds of millions of years of evolution, mostly replaced by the emergence of new bryozoans that sprang up in the later period, with a dozen or so varieties of multifin remaining, and only one surviving species of bowfin living in North America.
Because the multifinned fish is more common, we are relatively familiar with, so focus on the first: the name of the multifinned fish may be unfamiliar to some fish friends, but mention its common name "dinosaur", we will be familiar with the King of the Ear Spotted Dinosaur.
Below a brief introduction to the history of the dinosaur's revolutionary family, 1789 Napoleon's army expedition to Egypt, some French scientists also traveled with the army at public expense, by the way, to study the local ecology.
One day, a young scientist named St. Cyran caught a dinosaur in the Nile River, and after seeing it, he sighed with emotion: "wow, the world actually has such a funny-looking fish, the collection of which, go back and study it." After going back, St. Silan dissected the fish and found many connections between fish and land animals, which provided an important basis for the theory that land animals evolved from primitive fish.
As we all know, fish are divided into two main groups -- hard-boned fish and cartilaginous fish -- and cartilaginous fish are more primitive; the existing hard-boned fish evolved from the ancient cartilaginous fish, and dinosaurs were the intermediate link in this evolutionary process.
Taxonomically, dinosaurs belonged to the subclass of the order Scleractinia, the striped-finned fishes, the order Polychaeta, and although they were a relatively primitive kind of scleractinian fishes, they had a lot of the characteristics of cartilaginous fishes, such as the bones constituting their skull, pectoral fins, and abdominal fins were still cartilaginous, the intestines were in the shape of a spiral flap, and there were spouting holes behind the eyes, and so on.
Dinosaur fish are barrel-shaped body, the body has a diamond-shaped hard scales, the head has a pair of short whiskers, pectoral fins rounded, pectoral fins and ventral fins at the root of the column of flesh, by the pectoral fins of the column of flesh dinosaur fish can use the pectoral fins in the water "standing", so that it looks more like a certain kind of reptile, "dinosaur fish" the name may be derived from this.
The most important feature of the dinosaur fish is that the dorsal fin is divided into small fins, some of which look like rows of small flags and others like rows of feathers when they are erected. Dinosaur fish are interesting to watch as they swim, flapping their pectoral fins rapidly as their body travels through the water like a submarine.
The dinosaur fish is a carnivorous fish, to feed the ability to accept, what small fish, breadworms, red worms, animal offal, chicken and so on as a list, but offal, chicken and so on mixed water, the first choice should be small fish. Dinosaur fish prey on the way generally for the guard, when the small fish swim to the mouth quickly bite, and then swallowed like a snake, in the hungry time will also take the initiative.
Some fishermen say that the dinosaur fish mainly rely on the sense of smell to find food, poor eyesight, this point of view, I do not agree, the general poor eyesight of the fish's eyeballs will be degraded very small, such as the Nile Devil, some fish, such as the carp family of blind fish and even eye degradation, but the dinosaur fish is not like this, have a pair of large "watery" eyes, I have also seen many times dinosaurs far away from the small fish to the active attack.
While the dino sometimes looks down at the bottom of the tank when searching for food, like a bloodhound looking for prey, and seems to rely on its sense of smell, I think its eyesight is much better than it seems.
