Rat fish will not attack other fish under normal circumstances, because their character is not fierce, so they will not attack other fish as long as there is enough food. However, when rats and other fish are mixed, they often lie prone on the sick fish and suck the mucus on the sick fish with their mouths. However, larger fish are afraid to attack, so breeders should pay attention to their size when mixing. In addition, although rats and fish have strong ability to remove algae in their infancy, they will become neurotic when they grow up. In addition, their swimming speed is also relatively fast, so they often suck other fish from time to time. If other fish are injured or sick, they will keep smoking. If the fish are seriously ill or die directly, they will eat them directly.

rat fish can be mixed with fairy fish, colorful fish, traffic light fish, silver shark, Mary fish and kissing fish. Mouse fish is a benthic fish, with strong disease resistance and adaptability, and mild personality. Under normal circumstances, they will not take the initiative to attack other fish, and they will become particularly active and lively only when they eat. Rats and fish usually hide in corners or aquatic plants to rest. As long as there is enough food, they will not attack other fish.
