Depends on the snake... Many of mine comes out of their hide to feed, but some I have to lift the hide and dangle... I even have one snake I have to lay the F/T on him and then lay the hide over to get him to eat....
I'm not into a feeding tub, many of them get stressed, curios and everything else then looking for food so I'm feeding all my snakes in their tubs and I've not have any trouble with it...
