Ok, so I just came back with a huge ton of crickets and after careful observation of Gnag, and some hard thinking about this whole situation, I think we might have a false bell. So, before we go ahead on this, I want to point out some things that could mean all of this is actually fruitless. Even though it is very likely she has Giardia, I want us to consider these facts first:

1. We have not done a fecal sample yet (I am already asking my parents if we could do one. Quick question: How much do they typically cost?).

2. Gnag is eating like her regular self right now, and acting the same way, too. I just purchased a full batch of 5 week crickets (the store I typically go to ran out over the last 3 days, and I only had earthworms to feed Gnag, which are not as inviting nor as fast moving as crickets), and she is gobbling down TONS of them (14 so far!!!).

3. The feces that I saw, I don't know if it actually had just came from her. She was in her cave, and either she pooped it out suddenly and it moved along with her when she swam out, or she kicked it up as she swam out (haven't done a gravel-move around/water change for 4 days at that point), and over time, underwater, it had lost its solidity. It was also split in half.

4. Why would it occur now, when Bumpy's giardia was eradicated 6 weeks ago, and Bumpy herself is showing 0 signs of Giardia?

5. Gnag's behavior has not changed, other than being slightly more skittish (however, that could be due to how I have been doing 25% water changes once every day over the last 2 days).

I'm definitely going to take her next feces for a fecal exam ASAP, but until I see a feces that Gnag just produced that is runny, I don't want to traumatize her and tear apart her beautiful enclosure all for nothing.

Sorry if I've wasted your time but before I leap into full on quarantine action, I'm going to do a fecal exam first, and keep a VERY close eye on our big chubby eating machine, as well as taking special precautions to wash my hands after handling Gnag or doing anything with her tank.
