Okay, well; a few days ago, I noticed that one of the Betta fish in my female community tank (her name is Royal, and she's a blue/red/brown Betta fish) was sitting at the top of the tank, in the back left corner, not moving and just breathing a little bit. I had to go to Bible camp, so I left and came back later. I went back into my room and she was still the same way!!!! 
My Mom got a 1-gallon jar out of the basement and we filled it with water and put her in it. The fish in the OTHER tank seem fine -- so I think it was just her.
I set the tank up on July 2nd and the biological filter is still establishing itself, so the pH/ammonia levels are soaring.
I have been monitoring the fish in her little jar and she has clamped fins, she's very lethargic/not moving, and she's NOT EATING. Royal has a bit of a red line on her side and I thought it was bacterial infection. I wanted to buy medication for it, but my Mom's response? "How do we know it's not something else? I'm not about to buy medication for her just to make it WORSE."
I have put Bettafix and Big Al's All-Purpose Water Conditioner in the tank and I think she STILL needs something.
Well, I checked some more this morning.... turns out I was right. (I think.) Royal's red line seems to be growing. The line is just above her bottom fins and it's bigger than last night. Do you think it could be bacterial infection?
The community tank is pretty dirty.... uneaten food and Tropica's POOP laying around (every time I look at Tropica, she is POOPING Well, ALMOST every time) and I didn't have time but I need to clean it soon. 
I can do that once I get home....
Metamorphic Rock, in the other tank, seems to be acting kind of funny, too.... but I can't isolate any more than 2 fish because I only have two jars! If I have to isolate Metamorphic, I'm pretty screwed!
The other fish seem to be fine....
Also, I have been administering a 1/2 tsp of Bettafix every day to the jar. I have to clean the jar tonight, though, because I'm feeding her small portions of food and IT ALL GOES UNEATEN.
Sorry this is so long; I'm trying to rule out all the possibilities!
Also, a side question: Is it normal for a male Betta fish to try to burrow under the rocks in his tank? Because I oftentimes hear Mr. Wimpy Fish moving the rocks in his tank. It looks like he is trying to commit suicide. XD And.... do I need to cover his tank? He hasn't tried to jump out YET.... And during the winter, should I maybe move him to a bigger tank? Like, my extra 5-gallon one that Tropica is not using anymore? (Because she lives in the community tank now?) Because during the winter my house and the fish tanks get really cold, and you can't heat a tank less than five gallons....
