Looks great! Cooking up well I see!
As for trapping a six-line, good luck, he’s a smart fish, and fast and agile swimmer.
He might dive in at one point but unless your sitting while it happens and your fast on the trigger, he can be in and out in seconds. Is he being a problem.?
I have never caught anything in a fish trap except slow stuff like crabs.
Fish just seem to stare at the trap for me.
Made a harpoon from elastic and wood meat skewer.
Got a gorilla crab with that. Lucky shot.
Only the net worked for me but that’s without much corals.
Now, once a fish is in, until he dies, he’s in.
