Recently, I got a new hermit and I guess you can call my tank an ISO tank. What are the best food for crabs in ISO?
I just put my hermit crab in isolation too and I've been searching the same topic as you, and from what I found so far everyone seems to recommend: high protein and energy foods. Honey. Peanut utter. Molasses.
