poor baby.. I'm glad you saved her and are taking such better care of her.
Both my male (I'm about75% positive they're male) axolotls are 10 months old, one of them will eat worms whole, but my other one won't. After introducing them to worms, my melaniod, Mowgli ate a whole one once. Then he would not take any food from me after that. So I cut the worms in half and he was all over them :)
I noticed that he had a much harder time than my white axolotl, Lilo, who just gobbled them up with no problem. But Mowgli took a few minutes to get his whole ones down, they would always move around a lot and he just couldn't eat them. But now he's back to eating again. Sometimes it takes a lil trial and error.
