Best method of catching a stubborn fish in established reef tank?

Pulling all my fish to out in QT to treat my display and subsequent fish for ich, but my Royal Gramma has continued to outsmart me. Here's what I've tried, two net approach, the feed and net switcheroo, and also the midnight flashlight blinding nab. I really don't want to have to tear my tank apart and risk kybcorals health. Any suggestions? TIA.
I use a piece of acrilic that I cut to fit in my tank and sectioned the tank off with it....I have caught a six line Wrasse and a agressive checkerboard Wrasse with that method, and with minimal disruption to the rest of my tank....fish traps have never worked for me.....I do the section off tank and 2 net method......

Did you cough that fish yet? I have same problem with my last fish yellow coris wrasse. Im thinking to use electric. Anyone done that? :)
 
After lights out get up in the middle of the night - turn on lights & go netting.
Caught my purple tang after chasing him from the rocks.
 
How big is the DT? If it's not a huge tank the High & Dry method outlined in the link below has always worked well for me.

Wow, never heard of the high and dry method, that's awesome. I would try this first and then a fish trap. I will usually feed only in my fish trap for a few days till the fish all learn to go there. Then i'll Starve the, for a day then feed to catch the fish.
 
I am in the process of moving my residents out of their cramped downtown apartment (BC32) to a much roomier 5 bedroom, 3 bath (75G) out in the burbs ;) I have used most of the techniques mentioned in the reefkeeping article, next on the list is the high and dry method. The soda bottle worked to catch my 2 peppermint shrimp, as they had started picking at my acans and zoas. After that, none of the fish would go near the trap, so I took it out for a couple of days. Then I tried putting it back in a different location. This time using magnets to hold the trap on the glass up near the top where the chromis and clowns tend to feed. When feeding time came, I blasted some mysis into the trap and 2 of the 3 chromis went right in. The rest of the fish were not fooled by my trickery, and retreated behind the live rock. The next night, after not feeding for 24 hours, I used the food in the net trick to grab up one of the clowns. Again, the rest of the fish basically flipped me 'the bird' and swam off to safety. Early that morning, around 2 am, I used the night attack method to scoop up the second clown with no struggle at all. I am now left with a chromis, royal gramma, bengaii cardinalfish, lawnmower blenny, and a cleaner shrimp to move. Hopefully the high and dry will do the trick! Happy reefing everyone!
 
I used an inverted bottle trap method to catch a wrasse. Maybe it'll work south a royal gramma.

Take a plastic bottle. Cut the top off below the neck and invert and put the top back into the cut out bottle. Put some tasty food inside and put it back upright in the tank.

When the fish goes into the bottle for the food you can take it out. The fish usually swims down away from your hands and deeper into the bottle.

Caught a flasher wrasse with this the other day.
 
Can't believe how well the lights off then quickly turn to full blast works. I just caught my 8" Emperor angel in a 300G tank full of live rock in about 15 seconds. Been trying to catch him for a week. Have to remove him for a few weeks to make some new additions to the tank and rearrange some rock before adding him back in. He is NOT happy with me but glad it was quick!

Yes a car battery works well. But you will need DC pulse and shouldn't do more than 25 watts output.

On the upside your corals will grow faster.
