Ideas
 

I have a 90 gallon with a corner herbie overflow. When I looked in this morning my coral beauty had manageed to get over the eggcrate gard into said overflow. I can't seem to get a net close to him due to the 2 standpipes and need to get him back into the display. I am in need of ideas here folks.
Thanks in advance

My cleaner wrasse and green chrmis get in there at least twice a week always nighttime I just reach I. And cuff him I use to be careful now it's in and out really fast lol good luck

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
