Hello! Sophie is my first betta, and she has always been a bit odd, but now I fear she's sick. I bought her back in September at Petco and she was always really active and hyper. A few weeks later, she randomly laid eggs (without a male, which I've read is really rare), and she still appears to have the egg sack on her belly to this day. She seemed completely normal for a while after this strange behavior, but over the course of the past couple weeks she's grown progressively less active and just sort of lays at the surface against her leaf hammock or her water heater. Occasionally she will freak out and dart about the tank alarmingly quickly, and the other day she hit the rocks so hard they moved! Like I said, she has always been hyper so she has always done something similar to this, but now it's getting alarming and she doesn't continue to swim around normally afterward - she just lays at the surface. Her gills seem to have some kind of red inflammation, too, but I change her 1-gallon bowl at least once a week. Is that not enough? Is she ok? Does she need medicine? Her bowl is kept at 78 degrees constantly, if that helps with anything. PLEASE HELP!
If these pictures aren't helpful, I can take more :) Thanks!
