Shimmying can be from several things including ammonia or nitrites. I'd suggest just doing big, 50%+, water changes as often as you can, daily is optimal. Go with dechlorinator & maybe the ammonia treatment but aloe can "gunk up" gills IMO. There are no fish that live where aloe vera does (it's a desert plant), so the whole "natural product" thing is moot.
I hear you on seeing tiny white specks, ahem, I'm of a "certain age" & need to take off my glasses to see clearly sometimes. But I can usually see ich "salt grains" on fish...It's stressful to fish to treat for a disease they might not have. I'd go with lots of clean water until you know for sure what you might be treating.
Is there any sign of "flashing" (rubbing or dashing against substrate or rocks)? It's how fish scratch an itch, also a sign of ich, but not definitive.
