I was toying with the idea of creating a highway for fish to travel around my garden. the ideas was transparent plastic tubes which are interconnected at open containers (so fish get some fresh air). some issues were: connecting the tubes to containers, stiff enough tubes, cleaning the tubes, ensuring that tubes do not clog by plant growth, preventing cat damage.

Well, what would the speed limit be? And would there be carpool lanes?
I expect that the fish will be jumping lanes. there should be special cat-view scenic lanes.
