I want to simulatie a robot (fish robot) in viscouse surroudings. I understand how solids interact in simulink multibody. But can i change the surrouding with some viscous material whose paratemeter one can change.
Or is there any other toolbox that one can use?

There is an underwater vehicle example that includes hydrodynamic and hydrostatic forces, which I believe will help you get started.

Oops, I messed up the video link. This is the example I had in mind:
You'll of course need some correlation for drag & lift in terms of velocity (and orientation?), in order to apply the right amount of force in the right direction. Multibody won't simulate the fluid itself, but can represent the effects of the fluid as force and moment on the vehicle, if you know what they should be.
