Can someone post a link or just give me a list of general meds to keep on hand in case I have to QT.
Also...the question about my hermit crabs...A couple weeks ago they molted so I bought them new shells. All kinds of sizes and shapes. So far only one of them has actually kept or should I say, moved into a new shell and that was only yesterday. They play with the shells all the time, it's very entertaining. So as I'm watching them "hop" out of their shell into the new shells and then back into their shell, I noticed that one of them looks different. It has a red fuzzy butt

The others are smooth creamy brown all the way to the end but not this one. Does this determind what sex it is, or is it a different kind of hermit crab, or does it have the fuzzy butt fungus?
