I did this on a trip to Japan but can't remember for the life of me where. Some museum. My wife and I drew fishes and then they were uploaded and we went to a room and watched them swim across walls/ceilings. Really cool experience

Teamlabs - Borderless, I also did the same : )

Very nice work. You could improve the tank rendering performance though...

One of the teamLab exhibitions, probably: https://www.teamlab.art/e/

I drew a fish but I couldn't find it anywhere when it switched to the tank. Perhaps you could highlight the user's own fish, at least initially?

EDIT: Tried again and now I see there is a highlight, but it's pretty hard to see a in a busy tank, the color contrast is not very high
