Domino

[little nellie]

Any suggestion in catching a very large Domino? He is about 4 inches and I had try the plastic type fish traps and even made a trap out of fish net material spanning 2 feet long with an openning of 1 foot wide. So far I manage to trap all my other fish with food as bait but not the Domino I want to catch. I have too many rock work with encrusted coral makes removing them out of the question.

Friends suggested spear and I even try gaft and a small bait hook on fishing line and it seem to aviod being catch. No matter what time of day, no light, light just on.

Is there any stun gun or stuff available?

thanks
