This depends on how important the water sloshing is to your application: If the tank is completely full, you could assume the water is a solid. That might be an oversimplification. You could also assume that the tank is a rigid body. For best results you'll need to perform a two way fluid-structural interaction simulation. That will capture the movement of the fluid and the deformation of the tank.There's quite a few published tutorials example on YouTube, for example, here's an AIM FSI tutorial to get you started:

Also, here's two videos of a seismic simulation of fluid filled tanks:
