All my axolotl will eat is fry. I only put 6 in at a time and a specific size. They don't nibble at her they actually hide from her. I do monitor the action as the tank is next to my bed. She'll eat bloodworms but spits out nightcrawlers, redworms & the 6 different kinds of pellets I've tried. She's very healthy and very active and playful

unlike what I've read axies that just sit and hide.
