water simulation in a confined space

Anybody have any ideas on how to run a water simulation in a confined
space like a fishbowl? I need to have the camera inside the fishbowl
while the water is slo****ng around and a dead fish is floating in the
water. Can I use FluidEffects? Blobby particles? Water needs to be
photo-realistic because it will be integrated into live action.

Has anybody done this that can can give me a brief rundown of the
technique they used?
