Axolotl Won't Eat!

[Raygator]

I've had it for about a week now and it ate when I brought it home but I've noticed for the past 4 days it hasn't eaten when I try to feed it, my water tested fine so what could be the reason for this? Also is there any way I can get it to eat? Or any foods it won't refuse?

Try krill, that has always been my last resort food test.

Problem is that krill doesn't float to I don't know of he would see it or smell it all the way at the top of the tank but I can try it
