Implement ml-agents in unity-project

I have a project in which fishes swim in a 2d-aquarium. I want the fishes to behave clever and need ml-agents neural networks therefore. I want the fish to start collecting food and learn how to adapt and survive on their own. Your job is to install ml-agents and make sure the fish start learning. Do not use pretrained models, make them learn live. Your get 55€, not more. (small project). Unity account is required to download the project file and upload the work that was done.
