HCA: Hermit Crab Association

Hello! I have given my crabs many foods. I started with JurassiDiet (Not a good idea), then went to making fresh foods (super time consuming), finally I am ordering food from a place called Just2OldCrabs. My question is, do I have to transition their old food into their new food? I know that some kinds of pets stomachs don’t like a dramatic food switch. Should I slowly mix in their new food with their old food so they get used to it? I don’t know how a crabs stomach works. Thank you so much!

No need to transition, being scavengers they're built to consume whatever is available to them. They may reject things several times before wanting it though!

Thank you! I never thought of it that way!
