Imo, the trick to getting off live is the amount of feeders you give WHEN you feed live.
Back when I had ATF's, I started starving on day #2. Day#1 was 1-2 minnows per ATF.
If you feed small amounts, it gets their curiosity deeper.
I recommend starving for 3 weeks at the size you have. I would also add some type of peaceful tank mate that will eat the small amount of dried food offered daily (or no tank mate and just remove uneaten food after 20min).
