EEEEEeeee!!!
You were right about the bubble nest! He's already started to build one! (I just got out of class, too!)

It's lined along the length of his tank in a single row and there's a few individual spots here and there.
(Almost as if he's laying the foundation for the biggest bubble nest ever....?
) He's even flaring again at my tablet pen and chasing my finger around the tank. Frankly, I can't see any more of that ich on him, period. Looks like the fungus might be hiding, too.
Augh, but his water's all murky-lookin' now.

Gotta go take an exam so I'll have to change it when I get back in about an hour and a half...
(Exams are the bane of my existence.
) I kinda hope I can buy a Whisper filter later today. That'll probably help keep his water just a little cleaner (and make it so the water changes will be less frequent, and thus less stressful).
