Moshiach No Fish Left in Egypt

The fish were exiled from the Land of Israel. At the time of the Redemption through Moshiach, when Egypt will have a downfall, they will seek a fish for a sick person and none will be found there, because the fish will return to the Land of Israel.

(See talk of the Lubavitcher Rebbe King Moshiach Shlita, Va’era 2 5752 (1992))
