How adorable! The only thing that stood out to me, was that none of the fish were (almost) still. Every time I look into a fish tank, there is almost always one bugger, who just chills around, moving really slowly, and that I missed in your simulation. 
When I was young, there was a god with infinite power protecting me. Is there anyone else who felt that way? And was sure about it? but the first time I fell in love, I was thrown down - or maybe I broke free - and I bade farewell to God and became human. Now I don't have God's protection, and I walk on the ground without wings, but I don't regret this hardship. I want to live as a person. -Arina Tanemura
