I had this idea to make a flock of fish in geometry nodes by distributing them in volume. And to animate it using set position + noise. Looks ok-ish but all instances of fish move together in the same time and in same way.

Does anyone know a way to randomise their movement? Like you can randomize scale using random value, but for set position offset. So that each instance is distorted in a different way.

I think you should realize instances to convert instances to mesh and then set offset in set position node:
