1. Advantages: Bare tank culture of rat fish is better to take care of first, and this culture method is more suitable for breeders with insufficient time. Secondly, breeders can effectively control the water quality, and can also avoid food residues or feces falling in the sand to pollute the water quality. Finally, breeding rats and fish in bare tanks is more convenient to clean up garbage, and breeders can fish out food residues and feces at any time to avoid the breeding of bacteria.

2. Disadvantages: Feeding in bare tanks will affect the nature of rats and fish. Because they have the habit of turning over sand, if they are not covered with sand in the fish tank, it will hinder their nature. Moreover, rats and fish like to hide in aquatic plants. If there are no aquatic plants, they will feel insecure. Moreover, the rats and fish raised in bare tanks will have worse physique than the rats and fish raised in grass tanks.

Rats and fish have low requirements for fish tanks, so long as they are ordinary fish tanks, they can be raised. If the breeder's budget for choosing the tank is sufficient, he can choose the fish tank with ultra-white glass, which will be more ornamental. However, different species of rat fish have different sizes, so breeders need to choose fish tanks according to their sizes and habits. In addition, breeders need to pay attention to quality and bearing capacity when selecting tanks, don't blindly pursue beauty, and forget the safety of fish tanks.
