Dry food

Still in the process of building my tanks and gathering both supplies and knowledge, I wanted to know if anyone had any thoughts on any of these items for newts? I plan to get a few Chinese Firebellys. I do plan on feeding them live food, as well as frozen as needed, but I would like to have some dry back ups just incase. Based on the Caudata for what they like to eat, a lot of these ingredients line up, I just wanted to hear other people’s opinions! TYIA!
