So a couple more updates on the reptiles:
Stool sample from the iguana did return positive for hookworms as I'd suspected, so he and Colombina both came down with me to the vet yesterday afternoon for Ivermectin. Colombina's was her second dose, so in just shy of three weeks--in two weeks, which would normally be the recommended timeline, the vet will be out because it'll be Christmas--we'll try to collect another stool sample from her, and bring it down when I take the iguana in for his second dose.
Additionally, since she pooped while I was able to notice it, I snagged a stool sample for the beardie as well, and brought it with me to the vet yesterday as well. Indeed, she does still have coccidia and hookworms, so she'll be going in on Monday for an exam (to determine dosage amount) and the beginning of her own now-third round of medication to deal with these pernicious, pertinacious parasites. (On the plus side, the only outward sign she still had anything is her poops; she eats like a champ, and has even started warming up to me, somewhat.)
Colombina did manage to gain ~14g in the last two weeks; she'd been at ~44g from what I remember, and this visit, she was 58g. Makes sense, she's definitely been eating well, but it's so good to get that confirmation that she's actually putting on weight. This kind of weight gain is actually not tremendously abnormal either, considering her age; with this, I'd estimate she's approximately 3-4 months old, which is about a month older than my earlier estimate from when I first got her. (Yes, her physical condition really has improved that dramatically!)
On the iguana, the vet did second my suspicion that it's male; in addition to the items I myself had noted, he actually checked the femoral pores, little pore structures on the underside of the upper leg (hence "femoral", i.e., associated with the femur), something I myself didn't want to try just yet because of his skittish nature. But, the vet noted that those, while still too young to tell for certain, did look like they were maturing into the more male-appearance pores; on mature males, especially during mating season (typically the summer months), the femoral pores are quite bloated and stick out from the body, often even protruding--some protrude so far they're called "spurs". We're still probably a bit too young to tell for certain, but for the vet to confirm--and he was confident enough that he did mark it in the chart--we're probably dealing with a male. So, probably LeChuck.
Alas, last night, a couple hours after getting back home, the iguana decided he was feeling good enough to try to scramble up the sides of the tank along the various sensor wires, managed to snag one of his rear claws on the screen top, and ripped it right out when he fell down. Thankfully, the damage appears to have been minimal; if indeed he only managed to tear off the claw, it'll grow back, just a little kinda fucked-up.
Beyond that, I spent most of last night arm-wrestling with additional Linux issues, while also trying to crank out a ROUGH first draft for my MS thesis. (I did succeed in the latter, at least!) Linux had just released a new kernel--or at least, a new kernel was uploaded to the Mint and Ubuntu repositories--but Mozilla products that weren't the most-current version--which were NOT available on the repositories last night--break within that kernel build so badly that it destroys the OS's compression algorithm, corrupting the build and making it unable to boot. Thankfully a Recovery-Mode fsck fixed it, but still, holy CRAP was that frustrating.
Good news is, I used the downtime while the computer figured out whatever crap it needed to do, to take care of the plants in the chameleon enclosure, watering the new arrivals and trimming up that Boston fern. The fern's overall mass probably shrank to half what it was, just removing dead matter; while yes, it had arrived in rough shape, I can just about guarantee the lack of humidity in that enclosure did a number on it too. I do have another fogger arriving soon, so hopefully I can get that implemented and start actually TRYING to raise the humidity in there.
