When I just tossed the live rat in the tank Beetlejuice would usually strike from his hide and ambush them as they came by.
Now my feeding day routine involves going to get the feeders, and then I will put the feeders to the side, wash my hands (and havent really handled the feeders yet).. and do handling, water change, spot cleaning, freshen up any substrate as needed, then put him back in the enclosure. I let him wander around and do his thing, usually goes up on a vine or log now. Once he's chill, I drop both feeders in (Crawler rats) and he will typically strike one from above, and when done, will go stalk the other one. Quite fascinating to watch.
I've never been struck at on feeding day, and I've very deliberate in how I handle/retrieve him (every time, not just feeding day).. mostly thanks to advice I obtained here.
