glad to see some humor is alive, but we still have yet to succeed offering up a possible solution to retrieve the critter.
I made mention in my apology post about near lights on or off, this is when I've been most successful netting fish.
Try turning the lights off a half hour or more before you want to catch him, offer up a small amount of food and turn on the lights. Chances are greater that the fight or flight reflex will be diminished by the sudden light change and the available food; And you can snag the little terrorist. (joke for those who didn't get it.)
Trying to net immediately following lights out usually nets results as well, just have enough light available for you to see the target.
The 'nem idea would likely rid you of the fish and provide a meal to the 'nem, however it reduces your likelihood of trading the fish for something less territorial.
Chromis are quiet fish, and prefer being in schools. If you can trade the domino for two chromis', you did well. Odd numbers of chromis ease the infighting within the school, at least from my experience.. I have several blue and green chromis' in my tanks schooling. Another less aggressive seems to be the yellow tailed blue damsel, not certain of the latin name, but the description is simple, just yellow on the tail. More territorial than the chromis', but not aggressive towards other species. They will spar for dominance within their own kind, again an odd number of fish seems to reduce this.
