Actually, make sure it DOES leak. When dry ice sublimates to CO2, it expands. You MUST vent it, or it will explode...no, not like violent fire TNT, but like any sealed container with expanding gas inside.
Maybe the inner bag of fish shouldn't leak, but whatever contains the solid CO2 must be able to vent.
