The Thai betta lives in the upper layer of the water, while the black shell shrimp only lives in the bottom of the water. Under normal circumstances, Thai fighting fish will not be black shell shrimp as food. But that doesn't mean it doesn't eat black shell shrimp. Because the black shell shrimp has a shell, the fish will not take the black shell shrimp as the first choice for food. When food is abundant, it does not eat black shell shrimp. But if the owner forgets to feed, the fish have no food source and become very hungry, they will eat black shell shrimp.
Thailand betta can be mixed with black shell shrimp together, but not all cases they can coexist peacefully. First of all, make sure the tank is deep enough, so that the upper and bottom of the water will be far apart, and the fish will not notice the existence of black shell shrimp. You can also plant some aquatic plants in the fish tank to provide a place for the black shell shrimp to escape.
The most important point is that in the process of mixed culture, we must ensure that the food of Thai fighting fish is sufficient. It is better to feed with floating feed to avoid swimming to the bottom of the water to find black shell shrimp when eating. The fish must be fed each time so that they do not search for other food. When the above conditions are met, Thai betta can be raised with black shell shrimp.
