Chinese perch-HOW TO GET OFF LIVE-PLEASE HELP

[Damascus]

I am at my wits end with this fish

6-8" perch and I cannot get it off live
It's in a 90g cube right now until I can get it off live
It will eat feeders from tongs, but not frozen feeders from tongs. I have gotten it to snag a piece of tilapia and shrimp once or twice since it was 3" but will not eat other foods other than live

I added two SB PACU to see if other fish can "teach" it that other items are food, it still doesn't care. I've tried starving for weeks and it snagged a shrimp from tongs a few weeks ago but nothing since.

Any help from people who have broken this fish off live?

Anyone?

Is this a fish I can continue to push or is this a species that will starve itself to its own detriment/death before adjusting?

Got it to eat a 1/4 of a shrimp on a string the other night but again, nothing since.
