And if it does not eat still I would (even if it is a step backward) try scenting with various things such as Tuna, Chicken broth, Anchovies (those have worked well for me with stubborn hatchlings)

i tried salmon and hot dog water.
i'll give those other things a shot.
and i just bumped up the temperature a few degrees. i'll check on the tub in a little bit.
