Both my overflow and return have gate vavles. I just close the overflow first to raise the water level in the tank then the return su it won't overflow. Give or take a few hours the fish smarten up and come out of there.

try getting strips of cheap plexiglass and divide off areas around your stand pipes and trap your fish in a larger area where you could use your net
