Dr. Frye got back to me very quickly! He suggested a fecal sample and treating with metronidizole and possibly panacur. The problem is that I can't get a fecal for Glurmo since he hasn't pooped in a while and I cleaned it out last time he pooped. And he's not eating so there's nothing to poop out! So I have a couple questions that hopefully can get answered here!
1. Is this a special kind of metronidizole or is it the same thing you could buy for a cat or dog? I'm considering buying some online (if it's cheaper than Dr. Frye's price anyways).
2. Are worms visible to the naked eye in the feces? I've never seen anything that looked at all like worms and I tend to inspect poops when I clean them out to make sure they're normal looking.
3. Where can I find a liquid calcium supplement? Is it something I can get at a pet store?

Thank you guys so much for your help. I'm starting to feel a little less worried about Glurmo!

EDIT: I found metronidizole for fish for like mega cheap... is it the same thing? What sort of dose do I need to use?
