Dinosaur fish can be oxygenated or not. Whether to be oxygenated or not can be decided by the breeder according to his actual situation. Regular oxygenation can avoid their lack of oxygen, and can also avoid the impact of lack of oxygen on them. And with enough oxygen, their gills can develop better.

But not giving them oxygen will not affect their normal life. Because dinosaurs have breathing-assisted organs, if the dissolved oxygen in the water is insufficient, they will float to the water surface to breathe the outside air. Breeders only need to ensure that the water quality they live in is clean, and then change the water regularly and quantitatively, and the oxygen in the water can be enough for them to absorb.

Dinosaur fish should be heated, because the most suitable water temperature for their growth is 22-28 ℃. In winter, the temperature is low, so breeders need to heat them to ensure their comfortable living environment. If the water they live in is too warm, they will stop eating and moving, and may suffer from diseases for a long time. Therefore, in winter, it is better for breeders to heat them. They may not be warmed in other seasons except winter. Because they can accept a wide range of temperatures, they can grow in water temperatures between 16-30 ℃. As long as the water temperature is stable between 16-30 ℃, they can live normally.
