Thanks everyone. I have an update and some added questions (didn't want to muck up the boards with a new post):
I ended up upgrading to a 12 gal tank yesterday. I set it up on Thursday, let it run overnight. Tested both small tank and new tank water, both had same parameters and temp, so I cupped the fish over. After a few minutes of buzzing around nervously, they started exploring their new home and seemed happy, but other fish still moving its mouth, sometimes more rapidly than others, but since the move I've noticed it more (links to videos below)
Today after a 40% water change I noticed a few things:
1) the fish with the mouth issue is at it again, back to doing it constantly and fairly rapidly - links to video below. Also I noticed today she's not moving around much, hovering near the top. I have a filter which does move the water pretty good and I bought a larger airstone with the larger tank. The other 3 fish are swimming around some but are acting different than usual: they are schooling more today which usually they swim separately or in a group of 2 more often than not (although they are schooling fish, so, I don't know...) and even they have longer periods where they are hovering around the top and not moving much. [edit: they've stopped doing this for now, not sure what was going on earlier]
2) I have bubbles everywhere: microbubbles which seem to be coming from the filter (the part where the filtered water comes back into the tank) - see pics, larger bubbles attached to the filter and part of the heater (normal?) and bubbles at surface (they tend to pop fairly quickly). Good, bad?
3) Tiny hairs (?) floating in the tank - not many, but I've spotted a few - and some attached to the filter pump (the holed part that sucks up the water; tried to take a pic but my camera is pretty old so it wouldn't pick up the hairs). Also saw what looked like fluffy cottony stuff floating around and attached to some decor; removed with my fingers, hard to see what it is, but gross lol What are these things? is it normal? Should I do another water change? I have a cat, so I'm hoping they aren't cat hairs. The lid is always on and/or closed unless I change the water or feed and the cat has no interest whatsoever in the tank (I know, odd), and I try to make sure I rinse my hands before putting them in the tank, but hairs do cling, so maybe that' 'what they are? Although my cat isn't white. Anyone else have this? Do I need to treat it?
4) when I turned everything back on after the water change I heard a grinding noise coming from the filter. Somehow gravel had gotten in there. I removed it with my fingers, turned it on again, made the noise again, checked it and another piece of gravel in there. I also saw something small and black floating at the top near the pump so I took it out and it looks like a piece of plastic something had broken off, but I can't tell what. I checked the pump and there's no way gravel that large could fit in there....? Anyway, after a couple of tries it stopped but not sure what's happening there.
Additional info: tank hasn't yet cycled, been up for 3 weeks with fish (well, the old tank was up for over 3 weeks, this current one a few days, but parameters test the same). Daily water changes. Ammonia levels constant from 0-0.25, hard to tell with the coloring of the tube and the chart, but definitely nothing over 0.25 yet, no nitrates/nitrites at all, ph between 7.4-7.6 as of this morning. Any advice on this?
Should it be taking this long to get nitrates?
Any advice? I want to help the fish if there's something wrong but I don't know what!
[edit] Did another water change this evening even though not sure if it was required but felt I had to do something. I also turned the light off. After a bit, all fish were swimming around, but the one that moves her mouth still does it (links to video below). Looks like something might be wrong with her mouth, almost like it's too big for her, like her bottom "lip" hangs out too far and i thought I saw a dark spot on the inside of her mouth on one side but hard to tell, could just be shadow, they move fairly quickly. She is getting chased a little (new tank, maybe they have to do the territory thing again) so maybe that's why she's isolating some. I don't know, but her mouth moving is what's bothering me the most. She also tends to hide more when the light is on (larger tank, more powerful light, maybe she doesn't like it? Is that possible?)
Pics attached of the bubbles (this was after the first water change; after the second, I didn't fill it as high so the filter can't be seen from the top of the water now) and one of my tank in general (I'm pretty proud of it lol) and links to the videos of the fish with the mouth issue (takes about 15-25 seconds into each video to get a good shot of her mouth) - sorry for the quality, taken with my old cheap non-smartphone, going to borrow the video cam from work next week, but for now at least you can see the way she moves her mouth:
