Alright. I've dealt with protozoa before, 2 years ago with Bumpy, so if it is that chances are it won't be too difficult to deal with.

Update:

Thermidor produced a firm but a little underdigested poop this morning, using that one for the fecal exam.

Got back from the Vet visit just now. According to the Vet, it may very well be Chytrid due to the rapid weight loss Thermidor is experiencing, which is very bad. It could also just be parasites of some sort. If it's the former, though, then it may well have come from my Firebelly Toads, or simply from Thermidor himself. But chances are it's from the toads, because I have reason to believe he was experiencing either Short Tongue or whatever he was now before the vacation as well as if I recall correctly he was starting to look skinny then too. However, that could simply have been the short tongue on it's first stages, so for now it all depends on the fecal exam.

The Good News is is that the fecal will cost me exactly 0.00$ and I can drop it off tomorrow. So, at least it's all underway. And I forgot to mention the vomiting, so that suggests parasites as well... Never thought I'd say this, but crossing my fingers it's parasites or a bacterial infection. We'll see tomorrow.
