Your method doesn't work with tangs. The fish I moved was in a tank on the same sump as the other tank for many months and fed the same food as them from the same cup. It had outgrown the 75 and had to go in the 240.Vote other - because I do not have a fish trap, neither an acclimation box - but I use my refugium as an acclimation box. Every newcomer I introduce will be in my refugium at least 14 days - sometimes longer. There is a couple of reason for this -
1. There is a lot of living food in the refugium and the transition to frozen dead food will go seamless.
2. It is a rather calm place that will slowly introduce the newcomers for my microbial community. No stress from other fish that already is adapted to my DT
3. The newcomers get the same smell as the old. I have done tests with this and it has not matter if the old fish could see the newcomers during the adaption or not - the important factor seems to be that they swim in nearly exact the same water for a while
From the moment I start with this way of introducing new fish - I have not seen any - I say any - aggression from the old against the newcomers then they been introduced into the DT. Last time was two tiny scooter blennies. No other fish have attacked them after the introduction. An I have som fish that´s know to be real bullies.
I think the acclimation tank is a very good tool if you do not have any refugium or QT. If you QT - IMO - it is important to do WC with help of the DT water rather often a week or two before introduction into the DT.

First off...... I cracked up at your name!! Genius!!!! What kind of combo unit do you have?I have both, in a single item. My fish trap is also an acclimation box.
When you need a trap you just need it!
I guess it depends on how quickly you need the offending fish out. Personally I have good patience and have never failed to catch a fish in a trap after letting them all feed in it for a few weeks.As someone mentioned on another thread, It's easier to just drain all the water out of the tank and pick the fish up off the bottom.
Those are some great points on reasons to use the refugium. I had never thought of the smell thing. I have never had a sense of smell so the idea a new fish will be better accepted if he smells the same after being in the refugium is interesting.Vote other - because I do not have a fish trap, neither an acclimation box - but I use my refugium as an acclimation box.

I agree with the idea of using the acclimation box and sinking it as well as moving it around. Gives the chance to really test better if the fish will be friendly.Your method doesn't work with tangs. The fish I moved was in a tank on the same sump as the other tank for many months and fed the same food as them from the same cup. It had outgrown the 75 and had to go in the 240.
I moved him right before lights out and fed the tank. I have read about your method and hoped it would work.
There was a big fight. The 3 tangs already in the tank chased the new one out of the rocks and up into a corner. Then the clown tang started really attacking. I netted him again and put him in the box for the night.
I have used the box before and like others said it accomplished nothing. I tried it twice when I added my second large angel. It floats around the top but when you release the fish the aggression starts. They pay no attention to the fish while it floats near the surface.
So this time I forced the aggression to come out by placing the box right on the bottom where the tangs spend most of their time. I did this in the morning. And they fought again but the box prevented any damage. I had placed a large red clay brick on it to sink it. They could not move the box. After a few hours they quit. At noon I moved the box to the right end of the tank and it started again. But not as bad as in the morning and it didn't last nearly as long.
By the end of the day I was able to release it again and everything was peaceful. I wish I had figured this out before it got beat up. I think it will be fine though. Today it is swimming from one end of the tank to the other right beside the 3 other tangs like they are best buddies.
Right now
I made my acclimation box from a cheap Kritter Keeper by drilling some holes in the bottom and gluing foam in the top to make it float. I tied a piece of fishing line so I can anchor it to something while it is floating. It has a little eyelet on the top where I removed the handle.
