Hexagonal dinosaur fish can be fed 1~3 times a day, and the feeding amount of each time can be selected according to the dinosaur fish's own situation until it stops eating. Because the hexagonal dinosaur fish is also known as the king of the big stomach, their food intake is quite amazing, but this kind of fish will not eat after it is full, so if it is found that the dinosaur fish no longer eats during the feeding process, the extra bait can be cleared out. In addition, the hexagonal dinosaur fish prefers to eat some live food, such as some small fish, shrimp and loach. Of course, you can also choose to give it some chicken liver, chicken heart or lean meat strips when raising. But it is better to cut these into small pieces and feed them with tweezers, because their eyesight is poor and it is difficult to be found if they are thrown directly into the water.
