I mean efficiency in the fish's movement forward. I might be slightly more difficult for the fish to move in a very small volume of water as opposed to an unbounded volume, but it will certainly be able to move.boneh3ad said:I am not actually sure what you are talking about, but if the flow is inviscid and incompressible (as I discussed in the statement you quoted), then there would be no such "loss of efficiency". There is no mechanism for dissipation.
Yes. It fills the space vacated by the fish.boneh3ad said:The water wouldn't just go to one end of the tank either. After all, it can't go back there and just pile up; it has to go somewhere.
A one "fish-unit" volume of fish moves to one end of the tank, while a one" fish-unit" volume of water moves to the other.
