Illness/Sickness: Baby axolotl struggling to eat need advice

Baby axolotl refuses to eat, what does this mean and how can I get him/her to start eating again? He/she looks a little pale, which I am not sure why. There is no current or anything that I am aware of that could be causing the stress, unless the paleness is from being in a darkened room (kept in the bathroom right now for safety to the axolotl). pH 7.6. The water is at adequate temp and daily water changes. Using Stress Coat. He/she is eating frozen bloodworms thawed out. He/she will go into a well established tank with sand substrate later. He/she has not been eating for several days now, but shows some interest in eating. Any worms that go into the mouth are usually spit back out. Axolotl is looking a little thin, large enough that it could swallow about half a cube or so of bloodworms if it wanted to.

Any advice is helpful thanks. I'll get some live black worms this week and see if that will encourage it.

EDIT

My axolotl is a GFP leucistic and it's a couple weeks old, about 2 inches (4 cm) long.

What size is your axolotl, and what colour ?

Trying live bloodworms may help as well. The paleness is common, as the bloodflow in an Axolotl's body decreases during periods of low activity, which results in a fading of color. I would recommend stopping the use of the stress coat, as I have seen nothing but odds results from its use. If you want to use water conditioners...use Aquasafe or AmQuel+.

I've used AmQuel+ before, I will look into it again. I thought Stresscoat was more beneficial because of the aloe. Is there some concern for health using this product?
The axolotl ate a little between last night and this afternoon. It seems to be eating enough to sustain it's self. I can tell it has eaten because it looks slightly wider. He/she responds to surface disruption and will come to the surface for food, but isn't interested in actually eating, more like snacking. I will get some live blackworms tomorrow and see if this helps.
