rat fish is a small tropical fish, native to South America, mainly distributed in Amazon River, Brazil, Argentina and other places. They don't have high requirements for their living environment. They like to live at a water temperature of 22-26 ℃. The acceptable water temperature is 18-28 ℃, and the maximum cannot exceed 30 ℃.
They like to inhabit places where the current is relatively fast, because this will increase their exercise and help maintain their health. Because they are very inactive, otherwise, they may die of obesity. The water quality can be kept neutral, and it is best to install some better filtration devices when breeding. Because they like old water, don't change water too frequently.
2. The hardness of the water for raising rats and fish is suitableThe hardness of the water where rats and fish live is about 500ppm, which is about 6-11dGH. They don't have high requirements on water quality, belong to benthic fish, and have the habit of hiding in sediment, so it is best to lay some sediment at the bottom of fish tank when breeding. They have strong disease resistance and low requirements for the surrounding environment. They can live in water with neutral or weakly acidic PH, and the PH value of water is about 6.5-8.5. They can't live in water that is too alkaline. They like old water. If they change water too often, they may get sick.
