I know how you feel, Sherri, I get sick from blackworms, just watching them squirm together. Earthworms don't bother me, it is just the cutting up part that does because I feel like it is insanely cruel... but my axolotls do need to eat.
Frozen bloodworms are very good. They are rich in nutrients, but offering a veriety is also important. You can also feed raw shrimp, brine shrimp, gut loaded crickets, black worms (if you can stand them) Axolotl pellets.
I actually came across some interesting food in the petshop. It is called New And Salamander bites. After reading the ingredients, it sounds like it would be pretty nutrisous for axolotls, however, the bits are very small, so a large type of pellet would have to be purchased in the same brand.
I do not think you can get colony axolotl pellets over there from here in the states, but would you be able to order axolotl pellets online or find them in a pet store? They will probably not be the same as what the colony has to offer.
I read on this site that sinking or floating sticks, other salamander foods, and turtle foods can be offered. I've been feeding my two little babies the newt food along with the axolotl pellets, and they have been growing at a faster rate.

I think this sounds pretty good, but I wouldn't fed it as a stable. I feed it to my babies right now because I am finding it more difficult to keep blood worms as of recent in large amounts in my freezer. I keep enough to last me a few weeks, then have to purchase more later.
