Ruby fish is a tropical ornamental fish, suitable for living in water with temperature within 20-26℃. If the water temperature is not guaranteed during breeding, they will grow poorly and have various growth problems. So if you want to keep them healthy, you must pay attention to keeping the water temperature. If necessary, a heating rod can be installed in the fish tank to maintain the water temperature.

The ruby fish eats a lot and needs to be fed twice a day during breeding. But don't let them get too full when feeding, or it will not be good for their growth. It's best to let them eat 7-8% full every time.

When breeding, it should be noted that they have fish eating habits and can eat other small fish. Therefore, it is not recommended to keep them in the same tank as some smaller fish.
