I've been poring over the stickies on diseases and illnesses for a while now, and inspecting Feyd in between pages. I'm not sure if I need to panic, or if I'm making a big deal out of nothing.
Since yesterday, he has been "breathing" heavily through his gills. He has not been lethargic, if anything he's been more inquisitive and active than usual. He has been chucking hissy fits with me and flaring at me when I come up to his tank occasionally, I don't know what that's about either...
I can't figure out if his gills are red or inflamed-looking, because they are black, and always have been, which makes it pretty difficult to tell if there's an issue via looking for discolouration.
Anyway, here's the questionnaire filled out, and I hope that someone has better eyes than mine if there are any visual indicators of what might be wrong, photos are after the questions.

(Note: The "white dots" in the first picture aren't actually on him, they're due to my apparently non-existant glass-cleaning skills.)
If anyone has any ideas as to whether something is wrong, and if so, what it could be, I would be extremely grateful. Thank you.
