Hey guys,
Here's an update on my turtle (now dubbed Mulan by my sister because he apparently likes to stare at his reflection

):
He was eating for about a week before he stopped a couple of days ago. When he was eating, he didn't have the same appetite as he used to (a couple pellets at most, apparently dislikes shrimp now), before he suddenly stopped eating. He always spend the majority of his time basking on his rock, and seems somewhat lethargic, but still moves around (usually when his bigger companion sees no one else around and decides to bask then).
I've checked for signs of RI and the only symptoms I can list for him are:
Somewhat labored breathing occasionally (his neck cranes out and he opens his mouth for air),
He now refuses any food I offer him, although I've got some Anacharis to see if he'll eat that,
Around 3 weeks back, I heard him sneeze/cough when I would clean his tank, but I think that was only because of the tank temperature, which has increased since I installed the lamps. Otherwise, he doesn't cough or sneeze anymore,
No mucus around the mouth or nose, and no swollen eyes either.
I researched around for any home remedies I could try, since Mulan's symptoms seem very minor and I could never get my parents to take him to a vet and there aren't many herp vets, much less herp vets for aquatic turtles in my area. The main medicine I see for treatment of RI is baytril. However, I am not sure where to buy baytril and what dosage I'd need my little guy, especially since he's a baby (1 1/2 inches). I'm not sure whether it would be appropriate, given he's showing only a few of the symptoms.
P.S. Are there alternatives to Baytril? I've heard that once a turtle tries it, they hate it and it's hard to give them another dose. Also, my bigger turtle is 2 inches, and I think he's about to start shedding his skin normally and recently his scutes. Any specific food recommendations to encourage scutes to fall off?
I've also got a video link of the little guy:
